British nationality law

British nationality law is the law of the United Kingdom which concerns citizenship and other categories of British nationality. The law is complex due to the United Kingdom's historical status as an imperial power.

History
English law and Scots law have always distinguished between the Monarch's subjects and aliens, but British nationality law was uncodified until the British Nationality and Status of Aliens Act 1914 codified existing common law and statute, with a few minor changes.

Some thought the single Imperial status of British subject as increasingly inadequate to deal with a Commonwealth with independent member states. In 1948, the Commonwealth Heads of Government agreed that each member would adopt a national citizenship (Canada had already done so), but that the existing status of the British subject would continue as a common status held by all Commonwealth citizens.

The British Nationality Act 1948 established the status of Citizen of the United Kingdom and Colonies (CUKC), the national citizenship of the United Kingdom and colonies on 1 January 1949. Until the early 1960s there was little difference, if any, in UK law between the rights of CUKCs and other British subjects, all of whom had the right at any time to enter and live in the UK.

Independence Acts, passed when the remaining colonies were granted independence, contained nationality provisions. In general, these provisions withdrew the status of CUKC from anyone who became citizens of the newly independent country, unless one had a connection with the UK or a remaining colony (e.g. through birth in the UK). Exceptions were sometimes made in cases where the colonies did not become independent. (Notable cases include Penang and Malacca, which were made part of the Federation of Malaya; and Hong Kong, which became part of the People's Republic of China: CUKC status was not withdrawn from CUKCs from Penang and Malacca, and a new British nationality status was created for Hong Kong.)

Between 1962 and 1971, as a result of fears about increasing immigration by Commonwealth citizens from Asia and Africa, the UK gradually tightened controls on immigration by British subjects from other parts of the Commonwealth. The Immigration Act 1971 introduced the concept of patriality, by which only British subjects with sufficiently strong links to the British Islands (i.e. the UK, the Channel Islands and the Isle of Man) had right of abode, the right to live and work in the Islands.

The principal British nationality law now in force is the British Nationality Act 1981, which established the current system of multiple categories of British nationality, viz. British citizens, British Overseas Territories citizens, British Overseas citizens, British Nationals (Overseas), British subjects and British protected persons. Only British citizens and certain Commonwealth citizens have the automatic right of abode in the UK.

The 1981 Act ceased to recognise Commonwealth citizens as British subjects. There remain only two categories of people who are still British subjects: those (formerly known as British subjects without citizenship) who acquired British nationality through a connection with former British India, and those connected with the Republic of Ireland before 1949 who have made a declaration to retain British nationality. British subjects connected with former British India lose British nationality if they acquire any other.

In spite of the fact that the 1981 act repealed most of the provisions of 1948 act and the nationality clauses in subsequent independence acts, the acquisition of new categories of British nationality created by the 1981 act was often dependent on nationality status prior to 1 January 1983, the date the 1981 act came into effect, so many of the provisions of the 1948 act and subsequent independence acts are still relevant. Not taking this into account might lead one to the erroneous conclusion, for example, that the 1981 act's repeal of the nationality clauses in the Kenya Independence Act of 1963 restored British nationality to those who lost their CUKC status as a result of Kenya's independence in 1963. This is one of the reasons for the complexity of British nationality law; in complicated cases, determining British nationality status requires an examination of several nationality acts in their original form.

Classes of British nationality
There are currently six classes of British national.

Active categories

 * British citizen
 * British citizens usually hold this status through a connection with the United Kingdom, Channel Islands and Isle of Man ("United Kingdom and Islands"). Citizens of the United Kingdom and Colonies (CUKCs) who possessed right of abode under the Immigration Act 1971 through a connection with the UK and Islands generally became British citizens on 1 January 1983.


 * British citizenship is the most common type of British nationality, and the only one that automatically carries a right of abode in the UK.


 * Other rights can vary according to how the British citizenship was acquired. In particular there are restrictions for 'British citizens by descent' transmitting British citizenship to children born outside the UK. These restrictions do not apply to 'British citizens otherwise than by descent'.


 * British Overseas Territories citizen (formerly British Dependent Territories citizenship) (BOTC)


 * BOTC (formerly BDTC) is the form of British nationality held by connection with an overseas territory. It is possible to hold BOTC and British citizenship simultaneously. Nearly all are now also British citizens as a result of the British Overseas Territories Act 2002.

Residual categories
The four residual categories are expected to become extinct with the passage of time. They can be passed to children only in exceptional circumstances, e.g., if the child would otherwise be stateless. There is consequently little provision for the acquisition of these classes of nationality by people who do not already have them.


 * British Overseas citizen (BOC)


 * BOCs are CUKCs who did not qualify for British citizenship or British Dependent Territories citizenship. Most derived their status as CUKCs from former colonies, such as Malaysia and Kenya, because of quirks and exceptions in the law that resulted in their retaining CUKC status in spite of the independence of their colonies. This is fairly uncommon: most CUKCs (including those from Malaysia and Kenya) lost their CUKC status upon independence.


 * British subject


 * British subjects (as defined in the 1981 Act) are British subjects who were not CUKCs or citizens of any other Commonwealth country. Most derived their status as British subjects from British India or the Republic of Ireland as they existed before 1949.


 * British National (Overseas) (BN(O))


 * The status of BN(O) was created by the Hong Kong Act 1985 and the British Nationality (Hong Kong) Order 1986. BN(O)s are Hong Kong British Dependent Territories citizens who applied for the status of BN(O) before the handover of Hong Kong to the People's Republic of China. Hong Kong BDTCs who did not apply to become BN(O)s and did not gain Chinese nationality after the handover became British Overseas citizens if they did not have any other nationality.


 * British protected person (BPP)


 * BPPs derive from parts of the British Empire that were protectorates or protected states with nominally independent rulers under the "protection" of the British Crown, not officially part of the Crown's dominions. The status of BPP is sui generis – BPPs are not Commonwealth citizens ('British subjects', in the old sense) and were not traditionally considered British nationals, but are not aliens either.

Relationship with right to abode
Only the status of British citizen carries with it the right of abode somewhere (in this case the UK), and all British passports include a note to this effect. In practice BOTCs (except those associated with the Sovereign bases in Cyprus) were granted full British citizenship in 2002, BN(O)s have right of residence in Hong Kong (note: not conferred by the BNO status), BSs and BPPs lose their statuses upon acquisition of another nationality (except BSs connected with the Republic of Ireland) and so should be eligible for registration as British Citizens under the Nationality, Immigration and Asylum Act 2002.

British Overseas Citizens are unique in that their nationality status is not associated with a right of residence.

Acquisition of British citizenship
British Citizenship can be acquired in the following ways:
 * 1) lex soli: By birth in the UK to a parent who is a British citizen at the time of the birth, or to a parent who is settled in the UK
 * 2) lex sanguinis: By birth abroad, which constitutes "by descent" if one of the parents is a British citizen otherwise than by descent (for example by birth, adoption, registration or naturalisation in the UK). British citizenship by descent is only transferable to one generation down from the parent who is a British citizen otherwise than by descent, if the child is born abroad.
 * 3) By naturalisation
 * 4) By registration
 * 5) By adoption

For nationality purposes, the Channel Islands and Isle of Man are generally treated as if they were part of the UK.

Information about British citizenship and other kinds of British nationality is available from Her Majesty's Government. Information is also available on provisions for reducing statelessness.

Persons acquiring citizenship by method (2) are called citizens by descent; those acquiring citizenship by methods (1), (3) or (5) are called citizens otherwise than by descent. British citizens by registration, method (4), may be either, depending on the circumstances. Only citizens otherwise than by descent can pass on their citizenship to their children born outside the UK automatically; citizens by descent can pass on citizenship to their non-UK born children only by meeting certain UK residence requirements and registering them before the age of 18.

British citizenship by birth in the United Kingdom
From 1 January 1983, a child born in the UK to a parent who is a British citizen or 'settled' in the UK is automatically a British citizen by birth.
 * Only one parent needs to meet this requirement.
 * "Settled" status usually means the parent is resident in the UK and has the right of abode, or holds Indefinite Leave to Remain (ILR), or is the citizen of an EU/EEA country and has permanent residence, or otherwise unrestricted by immigration laws to remain in the UK. Irish citizens in the UK are deemed settled for this purpose.
 * Special rules exist for cases where a parent of a child is a citizen of a European Union or European Economic Area member state, or Switzerland. The law in this respect was changed on 2 October 2000 and 30 April 2006. See below for details.
 * For children born before 1 July 2006, if only the father meets this requirement the parents must be married. Marriage subsequent to the birth is normally enough to confer British citizenship from that point.
 * Where the father is not married to the mother, the Home Office usually registers the child as British provided an application is made and the child would have been British otherwise. The child must be under 18 on the date of application.
 * Where a parent subsequently acquires British citizenship or "settled" status, the child can be registered as British provided he or she is aged under 18.
 * If the child lives in the UK until age 10 there is a lifetime entitlement to register as a British citizen. The immigration status of the child and his/her parents is irrelevant.
 * Special provisions may apply for the child to acquire British citizenship if a parent is a British Overseas citizen or British subject, or if the child is stateless.

Even if a child born in the UK on or after 1 January 1983 does not acquire British citizenship, he/she does not require a visa (leave to enter or remain) to live in the UK. However, he/she is subject to immigration control and needs to obtain leave to enter if he/she leaves the UK and seeks re-admission, or leave to remain where permission is sought for the child to be allowed to stay in the UK.

Before 1983, birth in the UK was sufficient in itself to confer British nationality irrespective of the status of parents, with an exception only for children of diplomats and enemy aliens. This exception did not apply to most visiting forces, so, in general, children born in the UK before 1983 to visiting military personnel (e.g. US forces stationed in the UK) are British citizens.

British citizenship by descent
"British citizenship by descent" is the category for the children born outside the UK to a British citizen. Rules for acquiring British citizenship by descent depend on when the person was born.

From 1983
A child born outside the UK on or after 1 January 1983 automatically acquires British citizenship by descent if either parent is a British citizen otherwise than by descent at the time of the birth.
 * At least one parent must be British otherwise than by descent.
 * As a general rule, an unmarried father cannot pass on British citizenship automatically in the case of a child born before 1 July 2006. If the parents marry subsequent to the birth the child normally becomes a British citizen at that point if legitimated by the marriage and the father was eligible to pass on British citizenship. If the unmarried British father was domiciled in a country that treated (at the date of birth of the child born before 1 July 2006) a child born to unmarried parents in the same way as a child born to married parents, then the father passed on British citizenship automatically to his child, even though the child was born before 1 July 2006 to unmarried parents. Such countries are listed in the UK Home Office Immigration and Passport Services publication "Legitimation and Domicile". Failing that, the child can be registered as British if it would have been British if parents were married and application is made before the child is 18.
 * Where the parent is a British citizen by descent additional requirements apply. In the most common scenario, the parent is normally expected to have lived in the UK for three consecutive years and apply to register the child as a British citizen while the child is a minor (clause 43, Borders, Citizenship and Immigration Act 2009, effective from 13 January 2010). Prior to this date, the age limit was 12 months.
 * For British nationality purposes, the Isle of Man and Channel Islands are treated as though they were part of the UK.
 * Before 21 May 2002, British Overseas Territories were treated as 'overseas' for nationality purposes. The exceptions were Gibraltar, British citizens under the British Nationality Act 1981; and the Falkland Islands, granted British citizenship following the Falklands War under the British Nationality (Falkland Islands) Act 1983. Children born on or after 21 May 2002 in a British Overseas Territory (other than the Sovereign Base Areas of Cyprus) are entitled to British citizenship on the same basis as UK-born children.
 * Children born overseas to parents on Crown Service are normally granted British citizenship otherwise than by descent, so their status is the same as it would have been had they been born in the UK.
 * In exceptional cases, the Home Secretary may register a child of parents who are British by descent as a British citizen under discretionary provisions, for example if the child is stateless.

Before 1983
Before 1983, as a general rule "Citizenship of the UK and Colonies" (CUKC) was transmitted automatically only for one generation, with registration in infancy possible for subsequent generations. Transmission was from the father only, and only if the parents were married. (See History of British nationality law.)

In 1983, the status of CUKC was abolished. CUKCs who held Right of Abode in the UK became British Citizens. This included some people born outside the UK with no UK ancestry.

From 20 July 2009, the Borders, Citizenship and Immigration Act 2009 provides that a person born outside the UK to a British mother may be entitled to register as a British citizen by descent if that person was born before 1 January 1983. Before the 2009 changes, only persons born after 7 February 1961 and before 1 January 1983 were eligible for this provision that came into force in April 2003. However those with permanent resident status in the UK, or who are entitled to the right of abode, may prefer naturalisation as a British citizen, which gives transmissible British citizenship otherwise than by descent. Requirements for successful registration with form UKM are that the applicant be a child of a British mother born before 1983 and be of good character and attend a citizenship ceremony. As of 22 November 2010, there is no longer an application fee (of £540). Applicants do however still have to pay £80 for the citizenship ceremony.

Children born abroad to British mothers before 1983
There are two paths through which children of British mothers and children of British fathers born abroad before 1983 can acquire a passport, and the differences have a bearing on costs. Children of British mothers born before 1983 may require a nationality registration fee, which (as of 22 November 2010) is free (although they must pay £80 for a citizenship ceremony). They also must undergo a background check into their eligibility and be of "good character" and attend the citizenship ceremony.

British citizenship by adoption
A child adopted by a British citizen acquires British citizenship automatically only if:
 * the adoption order is made by a court in the UK, Channel Islands, Isle of Man or Falkland Islands on or after 1 January 1983, or in another British Overseas Territory on or after 21 May 2002; or
 * it is a Convention adoption under the 1993 Hague Convention on Intercountry Adoption effected on or after 1 June 2003 and the adopters are habitually resident in the UK on that date.

In both cases, at least one adoptive parent must be a British citizen on the date of the adoption.

The requirements are different for persons adopted before 1983.

In all other cases, an application for registration of the child as a British citizen must be made before the child is 18. Usually this is granted provided the Secretary of State accepts the adoption is bona fide and the child would have been a British citizen if the natural child of the adopters. Usually the adoption must have taken place under the law of a 'designated country' (most developed nations along with some others are 'designated' for this purpose) and be recognised in the UK. This is the standard method for children adopted by British citizens permanently resident overseas to acquire British citizenship.

The cancellation or annulment of an adoption order does not cause loss of British citizenship acquired by that adoption.

British children adopted by non-British nationals do not lose British nationality, even if they acquire a foreign nationality as a result of the adoption.

Any person who obtains British nationality by this method are British otherwise than by descent, which means they have the same status as those born or naturalised in the UK and can pass on British nationality to their children.

British citizenship by naturalisation
Naturalisation as a British citizen is at the discretion of the Home Secretary, who may grant British citizenship to anyone they "think fit". Although the Home Office sets down official requirements for naturalisation they may waive any of them, or may refuse citizenship to a person even if they meet all of the requirements. However, applications for naturalisation are normally granted if the requirements are met.

The requirements for naturalisation as a British citizen depend on whether or not one is the spouse or civil partner of a British citizen.

For those married to or in a civil partnership with a British citizen, the applicant must:
 * Have held indefinite leave to remain in the UK (or an "equivalent" (for this purpose) such as the right of abode, Irish citizenship, or permanent residency as a citizen of an EU/EEA country or a family member of one) at the time they apply for naturalisation. As of 12 November 2015, EEA nationals are explicitly required to obtain a proof of permanent residency in the UK (in the form of permanent residency certificate) if they are to become a British citizen by naturalisation
 * Have lived legally in the UK for three years
 * Be of "good character", as deemed by the Home Office (in practice the Home Office carries out checks with the police and with other Government departments)
 * show sufficient knowledge of life in the UK, either by passing the Life in the United Kingdom test or by attending combined English language and citizenship classes. Proof of this must be supplied with one's application for naturalisation. Exemption from this and the language requirement (see below) is normally granted for those aged 65 or over, and may be granted to those aged between 60 and 65. Note that this is required for permanent residency, not just for citizenship, and married partners may be deported if they are unable to pass the test. The test has attracted controversy for being "like a bad pub quiz" and the subject of a critical, comprehensive report by Thom Brooks.
 * Meet specified English, Welsh or Scottish Gaelic language competence standards. Those who pass the Life in the UK test are deemed to meet English language requirements

For those not married to or in a civil partnership with a British citizen, the requirements are:
 * Five years' legal residence in the UK
 * Indefinite leave to remain or "equivalent" for this purpose (see above) must have been held for 12 months
 * the applicant must intend to continue to live in the UK or work overseas for the UK government or a British corporation or association
 * the same "good character" standards apply as for those married to British citizens
 * the same language and knowledge of life in the UK standards apply as for those married to British citizens

Those applying for British citizenship in the Channel Islands and Isle of Man (where the application is mainly based on residence in the Crown Dependencies rather than the UK) do not have to sit the Life in the UK Test. In the Isle of Man, there is a Life in the Isle of Man Test, consisting of certain questions taken from the Life in the UK Test syllabus and certain questions taken from a separate syllabus relating to matters specific to the Isle of Man. In due course it is expected that Regulations will be introduced to that effect in the Channel Islands. The provisions for proving knowledge of English, Welsh or Scottish Gaelic remain unchanged until that date for applicants in the Crown Dependencies. In the rare cases where an applicant is able to apply for naturalisation from outside the United Kingdom, a paper version of the Life in the UK Test may be available at a British diplomatic mission.

, wait times for naturalisation applications were reportedly up to 6 months. The UK Border Agency stated that this was occurring because of the widespread changes proposed to the immigration laws expected to take effect in late 2009.

Fees for naturalisation (including Citizenship ceremony fee) have been rising steadily at the rate faster than inflation; in 2013 the fee was £874 for single applications, £1,550 for joint application for husband and wife or civil partners living together if applying at the same time. In 2015 the fee for a single applicant increased to £1005.

Citizens of EEA States and Switzerland
The immigration status for citizens of European Economic Area states and Switzerland has changed since 1983. This is important in terms of eligibility for naturalisation, and whether the UK-born child of such a person is a British citizen.

Before 2 October 2000
In general, before 2 October 2000, any EEA citizen exercising Treaty rights in the United Kingdom was deemed "settled" in the United Kingdom. Hence a child born to that person in the United Kingdom would normally be a British citizen by birth.

2 October 2000 to 29 April 2006
The Immigration (European Economic Area) Regulations provided that with only a few exceptions, citizens of EU and European Economic Area states were not generally considered "settled" in the UK unless they applied for and obtained permanent residency. This is relevant in terms of eligibility to apply for naturalisation or obtaining British citizenship for UK born children (born on or after 2 October 2000).

30 April 2006 onwards
On 30 April 2006, the Immigration (European Economic Area) Regulations 2006 came into force, with citizens of EEA states and Switzerland automatically acquiring permanent residence after 5 years' residence in the UK exercising Treaty rights.

Children born in the UK to EEA/Swiss parents are normally British citizens automatically if at least one parent has been exercising Treaty rights for five years. If the parents have lived in the UK for less than five years when the child is born, the child may be registered as British under section 1(3) of the British Nationality Act once the parents complete five years' residence.

Children born between 2 October 2000 and 29 April 2006 may be registered as British citizens as soon as one parent has completed five years' residence exercising Treaty rights in the UK.

Irish citizens
Irish citizens, because of the Common Travel Area between the UK and Ireland, are exempt from these restrictions and are normally treated as "settled" in the UK immediately upon taking up residence.

Swiss citizens
From 1 June 2002, citizens of Switzerland are accorded EEA rights in the UK.

Citizens of Greece, Spain and Portugal
Greek citizens did not acquire full Treaty rights in the UK until 1 January 1988 and citizens of Spain and Portugal did not acquire these rights until 1 January 1992.

Ten years rule
Non-British children with an EEA or Swiss parent may be registered as British once the parent becomes "settled" in the UK under the terms of the Immigration Regulations dealing with EEA citizens.

A separate entitlement exists for any such UK-born child registered as British if they live in the UK until age 10, regardless of their or their parent's immigration status.

Registration as a British citizen
Registration is a simpler method of acquiring citizenship than naturalisation, but only certain people are eligible.

British nationals (other than British citizens) who have indefinite leave to remain in the UK or right of abode, are eligible for British citizenship by registration after five years' residence in the United Kingdom. This is an entitlement under s4 of the 1981 Act (section 4 registration).

Other cases where persons may be entitled to registration (either as a matter of law or policy) include:
 * Children born in the UK where a parent obtains British citizenship or indefinite leave to remain after the child is born
 * Children born in the UK who live in the UK until age 10.
 * Children born to a British father who is not married to the mother
 * British Overseas citizens, British subjects and British protected persons who have no other nationality
 * Certain British nationals from Hong Kong who meet the requirements of the Hong Kong (War Wives and Widows) Act 1996 or the British Nationality (Hong Kong) Act 1997
 * British Nationals (Overseas) who do not hold any other citizenship or nationality before 19 March 2009 (see Borders, Citizenship and Immigration Act 2009 regarding the extension of Section 4B of the British Nationality Act 1981)
 * Persons born outside the UK to a British born or naturalised mother.
 * Certain children born outside the UK to a British citizen by descent
 * Certain children born in the UK who are stateless
 * Persons who acquire British overseas territories citizenship after 21 May 2002 (except those connected solely with the Sovereign Base Areas of Cyprus)
 * Children under 18 who are adopted outside the UK by British citizens
 * Former British citizens who renounced British citizenship

Acquisition of British Overseas Territories citizenship
The British Nationality Act 1981 contains provisions for acquisition and loss of British Dependent Territories citizenship (BDTC) (renamed British Overseas Territories citizenship (BOTC) in 2002) on a broadly similar basis to those for British citizenship. The Home Secretary has delegated his powers to grant BOTC to the Governors of the Overseas Territories. Only in exceptional cases is a person registered or naturalised as a BOTC by the Home Office in the UK.

On 21 May 2002, any BOTC who did not hold British citizenship (except those from the Sovereign Base Areas) automatically acquired it under the British Overseas Territories Act 2002. Those acquiring BOTC after that date are entitled to register as British citizens under s4A of the 1981 Act.

Acquisition of other categories of British nationality
It is unusual for a person to be able to acquire British Overseas citizenship, British National (Overseas), British subject or British protected person status. They are not generally transmissible by descent, nor are they open to acquisition by registration, except for certain instances to prevent statelessness.

The Nationality, Immigration and Asylum Act 2002 granted British Overseas Citizens, British Subjects and British Protected Persons the right to register as British citizens if they have no other citizenship or nationality and have not after 4 July 2002 renounced, voluntarily relinquished or lost through action or inaction any citizenship or nationality. Previously such persons would have not had the right of abode in any country, and would have thus been de facto stateless. Despite strong resistance from senior officials at the Home Office, the then Home Secretary, David Blunkett, said on 3 July 2002 that this would "right a historic wrong" that left stateless tens of thousands of Asian people who had worked closely with British colonial administrations.

Persons connected with former British colonies
British Overseas citizenship is generally held by persons connected with former British colonies and who did not lose their British Nationality upon the independence of those colonies.

British National (Overseas) and Hong Kong
Most former BDTCs by virtue of a connection with the former dependent territory of Hong Kong are now either British Nationals (Overseas) (with or without citizenship of the People's Republic of China), British Overseas citizens, or solely citizens of the PRC. (The deadline for registering as a British National (Overseas) passed in 1997.) There is no provision to acquire British National (Overseas), although stateless children born to such persons may be entitled to British Overseas citizenship and can apply to register as British citizens.

In some cases former BDTCs from Hong Kong have been able to acquire British citizenship (BC status) under legislation passed in 1990, 1996 and 1997. In other cases, some former Hong Kong BDTCs hold British citizenship as a matter of entitlement or through acquisition under normal rules.

Most of these BCs and BN(O)s have been recognized by the People's Republic of China as its citizens before and after the handover of Hong Kong. These PRC citizens of Hong Kong origin have been categorised differently from PRC nationals from Macao and Mainland China.

In February 2006, in response to extensive representations made by Lord Avebury and Tameem Ebrahim, British authorities announced that 600 British citizenship applications of ethnic minority children of Indian descent from Hong Kong were wrongly refused. The applications dated from the period July 1997 onwards. Where applicants in such cases confirm that they still wish to receive British citizenship, the decision is reconsidered on request. No additional fee is required in such cases. A template to request reconsideration is available for those who want a prior application reconsidered.

Persons born in the Republic of Ireland
Approximately 800,000 persons born before 1949 and connected with the Republic of Ireland remain entitled to claim British subject status under section 31 of the 1981 Act.

Descendants of the Electress Sophia of Hanover
Eligible descendants from the Electress Sophia of Hanover may hold British Overseas citizenship based on their status as British subjects before 1949. Where such a person acquired a right of abode in the UK before 1983, it is possible for British citizenship to have been acquired. See also History of British nationality law and Sophia Naturalization Act 1705.

Renunciation and resumption of British nationality
All categories of British nationality can be renounced by a declaration made to the Home Secretary. A person ceases to be a British national on the date the Home Secretary registers the declaration of renunciation. If a declaration is registered in the expectation of acquiring another citizenship but one is not acquired within six months of the registration, it does not take effect and the person remains a British national.

Renunciations made to other authorities (such as the general renunciation made as part of the US naturalization ceremony) are not recognized by the UK. The forms must be sent through the UK Border Agency's citizenship renunciation process. There are provisions for the resumption of British citizenship or British overseas territories citizenship renounced for the purpose of gaining or retaining another citizenship. This can generally only be done once as a matter of entitlement. Further opportunities to resume British citizenship are discretionary.

British subjects, British Overseas citizens and British Nationals (Overseas) cannot resume their British nationality after renunciation.

Automatic loss of British nationality
British subjects (other than British subjects by virtue of a connection with the Republic of Ireland) and British protected persons lose British nationality upon acquiring any other form of nationality.
 * These provisions do not apply to British citizens.
 * British Overseas Territories citizens (BOTCs) who acquire another nationality do not lose their BOTC status but they may be liable to lose belonger status in their home territory under its immigration laws. Such persons are advised to contact the governor of that territory for information.
 * British Overseas citizens (BOCs) do not lose their BOC status upon acquisition of another citizenship but any entitlement to registration as a British citizen on the grounds of having no other nationality no longer exist after acquiring another citizenship.

Revocation of British nationality
Under the Immigration, Asylum and Nationality Act 2006, people with dual nationality who are British nationals can be deprived of their British citizenship if the Secretary of State is satisfied that "deprivation is conducive to the public good"; there is a right of appeal. This provision has been in force since 16 June 2006 when the Immigration, Nationality and Asylum Act 2006 (Commencement No 1) Order 2006 came into force. Loss of British nationality in this way applies to people born in the UK as British citizens and who also hold another nationality. As the provision applies only to dual nationals, its application cannot render a person stateless.

The Home Office does not issue information on these cases and is resistant to answering questions, for example under the Freedom of Information Act 2000. at least 17 people had been deprived of their British citizenship, in most cases on the recommendation of MI5. It appears that the government usually waits until the person has left Britain, then sends a warning notice to their British home and signs a deprivation order a day or two later. Appeals are heard at the highly secretive Special Immigration Appeals Commission (SIAC), where the government can submit evidence that cannot be seen or challenged by the appellant.

Previously since 2003 under the Nationality, Immigration and Asylum Act 2002, British nationals could be deprived of their citizenship only if the Secretary of State was satisfied they were responsible for acts seriously prejudicial to the vital interests of the United Kingdom or an Overseas Territory.

British nationals who are naturalised or registered may lose British nationality if it was obtained by fraud or concealment of a material fact. The nationality laws of the US, Canada and Australia have similar provisions to revoke local nationality from citizens who gained such citizenship via naturalisation.

Visa requirements


Visa requirements for British citizens are administrative entry restrictions by the authorities of other states placed on citizens of the United Kingdom. In 2014, British citizens had visa-free or visa-on-arrival access to 175 countries and territories, the same as for American, Finnish, German and Swedish citizens and more than for any other citizens.

Visa requirements for other classes of British nationals such as British Nationals (Overseas), British Overseas Citizens, British Overseas Territories Citizens, British Protected Persons or British Subjects are different.

Dual nationality and dual citizenship
Since the British Nationality Act of 1948, there is in general no restriction in UK law on a British national being a citizen of another country.

Different rules apply to British protected persons and certain British subjects. A person who is a British subject other than by connection with the Republic of Ireland loses that status on acquiring any other nationality or citizenship, and a British protected person ceases to be such on acquiring any other nationality or citizenship. Although British Overseas citizens are not subject to loss of citizenship, British Overseas citizens may lose an entitlement to register as a British citizen under s4B of the 1981 Act if they acquire any other citizenship.

Many other countries do not allow dual nationality. If a person has British nationality and is also a national of a country that does not allow dual nationality, the authorities of that country may regard the person as having lost that nationality or may refuse to recognize the British nationality. British nationals who acquire the nationality of a country that does not allow dual nationality may be required by the other country to renounce British nationality to retain the other citizenship. None of this affects a person's national status under UK law.

Under the international Master Nationality Rule a state may not give diplomatic protection to one of its nationals with dual nationality in a country where the person also holds citizenship.

A British person who acquired foreign citizenship by naturalisation before 1949 may have lost British nationality at the time. No specific provisions were made in the 1948 legislation for such former British subjects to acquire or otherwise resume British nationality, and hence such a person would not be a British citizen today. However, women who lost British nationality on marriage to a foreign man before 1949 were deemed to have reacquired British subject status immediately before the coming into force of the 1948 act.

The UK is a signatory to the Convention on the Reduction of Cases of Multiple Nationality and on Military Obligations in Cases of Multiple Nationality (1963 Strasbourg Convention). Chapter 1 requires that persons naturalised by another European member country automatically forfeit their original nationality but the UK ratified only Chapter 2, so the convention does not limit the ability of British citizens to become dual citizens of other European countries.

British citizenship ceremonies
From 1 January 2004, all new applicants for British citizenship by naturalisation or registration aged 18 or over if their application is successful must attend a citizenship ceremony and either make an affirmation or take an oath of allegiance to the monarch, and make a pledge to the UK.

Citizenship ceremonies are normally organised by:
 * local councils in England, Scotland, and Wales
 * the Northern Ireland Office
 * the governments of the Isle of Man, Jersey and Guernsey
 * the Governors of British Overseas Territories
 * British consular offices outside the United Kingdom and territories.

Persons from the Republic of Ireland born before 1949 reclaiming British subject status under section 31 of the 1981 Act do not need to attend a citizenship ceremony. If such a person subsequently applies for British citizenship by registration or naturalisation, attendance at a ceremony is required.

For those who applied for British citizenship before 2004:
 * the oath of allegiance was administered privately through signing a witnessed form in front of a solicitor or other accredited person
 * those who already held British nationality (other than British protected persons) were exempt, as were those citizens of countries with the Queen as Head of State (such as Australia and Canada).

Citizenship of the European Union
British nationals who are "United Kingdom nationals for European Union purposes" are also citizens of the European Union and enjoy rights of free movement and the right to vote in elections for the European Parliament.

British nationals who are "United Kingdom nationals for European Union purposes", namely:
 * British citizens;
 * British subjects with the right of abode; and
 * British Overseas Territories citizens connected to Gibraltar

are European Union citizens under European Union law.

By virtue of a special provision in the UK Accession Treaty, British citizens who are connected with the Channel Islands and Isle of Man (i.e. "Channel Islanders and Manxmen") do not have the right to live in other European Union countries (except the Republic of Ireland through the long-established Common Travel Area) unless they have connections through descent or residence in the United Kingdom.

Statistics on British Citizenship: 1998 to 2009
The Home Office Research and Statistics Division publishes an annual report with statistics on grants of British citizenship broken down by type and former nationality. Since 2003, the report has also included research on take-up rates for British citizenship.
