In the first post in this series, I examined the route to naturalisation as a British Citizen for people who have obtained Indefinite Leave to Remain (ILR) or Settled Status in the UK. There are, however, other routes to becoming a British Citizen for people who meet very specific criteria. These routes are important because if one of them applies to you, you will be able to become a British Citizen much sooner than after the five-to-six-year wait that you would usually have to go through. Further or alternatively, you will have to satisfy far fewer overall requirements than those on the regular route to naturalisation.



You may be eligible for British Citizenship if you have another type of British nationality, you were born in the UK to parents without ILR, you were born abroad to a British parent, you are stateless or you are not already a British Citizen due to a historical unfairness.



Other Types of British Nationality


Due in large part to its colonial past, British nationality law is extremely complex, with a large number of different categories of British nationality in existence. In this regard, the UK is rather unique in having different types of nationality other than citizenship. These British nationals can usually become British Citizens one way or another, but crucially are not automatically British Citizens and must meet at least some of the naturalisation requirements in order to become one. Until they become full citizens, they are still subject to immigration controls despite being British nationals.



These other types of British nationality include:


  • British Overseas Territories Citizen (BOTC)
  • British Overseas Citizen (BOC)
  • British National (Overseas) (BN(O))
  • British Subject (BS)
  • British Protected Person (BPP)

Before the British Nationality Act of 1981 came into force on 1 January 1983, the status of “British Citizen” at all. Historically, people within the territory of the UK were referred to as “British Subjects”, while those born in British protectorates (i.e. nominally independent territories that were under the control but not formally part of the British Empire) had the status of “British Protected Persons”. On 1 January 1949, The British Nationality Act of 1948 turned people into “Citizens of the United Kingdom and Colonies” (CUKC), which included everyone born in the UK and its overseas colonies (and therefore based on the principle of Jus Solis). British Subjects born in former colonies that had already achieved independence retained that status if they did not become citizens of those newly independent colonies.



Not all CUKCs were treated equally, however, and for the next 30 years the British government, through a series of new immigration acts, limited the right to live and work in the UK to citizens either born in the UK itself or those with a parental link to the UK. The British Nationality Act 1981 formalised this by introducing “British Citizenship” for those born in the UK to parents with either British Citizenship or ILR and those born abroad to British Citizen parents, and every CUKC who did not meet those criteria became either a BOTC, a BOC or a BN(O), while BPPs and BSs retained their status.



Very simply put, BOTCs were former CUKCs living in the remaining colonies (now referred to as overseas territories), BOCs were people who, for a variety of reasons, retained their CUKC status after the colony they were based in achieved independence, while BN(O) status was created specifically for BOTCs in Hong Kong so that they could retain their British nationality after the sovereignty of Hong Kong was transferred to China in 1997 (those who did not register as BN(O)s before the transfer and who did not automatically become Chinese citizens became BOCs). Except for BOTC status, none of these can be acquired or transferred through descent, with some very rare exceptions for children of BOCs, BSs and BPPs where those children would otherwise be stateless. BOTC status can be transferred by birth if you were born in an overseas territory to parents who are either BOTCs or live there permanently. It can also be acquired by naturalisation.



Although the process of becoming a British Citizen is called “registration” for most of these British nationals and not “naturalisation”, in practice they are mostly the same but for a few differences. It has the same length of residence requirements, the same requirement to have Indefinite Leave to Remain (ILR), the same physical presence requirement and the same good character requirement. Since 21 May 2002, people who are BOTCs at birth are automatically British Citizens, so the only BOTCs who have to go through the registration/naturalisation route are those who obtained it through naturalisation.



Born in the UK


As was discussed above, since 1 January 1983 not everyone who is born in the UK becomes a British Citizen. There, however, are scenarios where people born in the UK can submit applications to become British Citizens if they are not already.


The first is if you are under 18 and your parents, who at the time of your birth were still on time-limited visas, have since obtained ILR and/or naturalised. The other is if you lived the first ten years of your life in the UK (you can apply for this at any age and any point after those ten years are over).



British Parent


All British Citizens will pass on British Citizenship to their children that are born in the UK, but it is a little more complicated for those born outside the UK.



Currently, a British Citizen born in the UK or a naturalised British Citizen will pass on British Citizenship to all their children that are born outside the UK. If any of those children, however, then have children who are also born outside the UK, that second generation will not automatically be born British Citizens. They register for British Citizenship, however, if they apply before they turn 18 and if their British Citizen parent has completed a three-year period of residence with fewer than 270 days of absences at some point before the child is born. If you do not have at least one grandparent born in the UK, then you will not be eligible for British Citizenship even if all your parents and grandparents are British Citizens, if they were all born outside the UK.





It may be possible to become a British Citizen if you do not have citizenship or nationality of any country and are, therefore, “stateless”. Whether you can do this depends on your personal circumstances, as well as being able to prove not only that you are not a citizen of any country and are genuinely stateless, but that you were born that way and have always been stateless. Similar to those with other forms of British nationality, the process is called “registration” but is very similar in many ways to naturalisation.



If you are stateless and born on or after 1 January 1983, the requirements depend on your place of birth or your parentage. If you were born in the UK or in an overseas territory, you will have to meet the same residency requirements as unmarried people with ILR have to meet for naturalisation and if you are under 18, you must also show that you are unable to acquire citizenship of any other country. This means you are expected to pursue every reasonable avenue to obtain another citizenship that you may be entitled to (in practice, you will need to show you are unable to obtain the citizenship that your parents and/or grandparents have if they are/were not also stateless). If you were born outside the UK, you will have to show you have at least one parent who is/was a British national (Citizen, BOTC, BOC or BS) and meet the same residency requirements as married people with ILR have to meet for naturalisation.



For those stateless people born before 1 January 1983, your eligibility for British Citizenship depends on whether your mother was a pre-January 1949 British Subject or a CUKC (depending on which side of 1 January 1949 you were born), or whether either of your parents was a post-January 1949 British Subject without formal citizenship of any country, at the time of your birth. Alternatively, you are eligible if you were born in a place which is within the UK or an overseas territory (or was at the point you submitted an application for British Citizenship).



Historical Unfairness


In recent years, there have been various changes to the law to allow people to become British Citizens if their reason for not being so at birth was due to some kind of historical unfairness, namely the unequal treatment of women and the children of unmarried couples.



Historically, a person born outside the UK or its overseas territories could only inherit British nationality if his or her father was British and his or her parents were married to each other. In order to correct these historical inequalities, there are a number of scenarios where you can register to become a British Citizen:



  • You were born before January 1983 outside the UK and you would have been a British Citizen, had your mother been able to pass on her British nationality in the same way as a man;
  • You were born before January 1983 outside the UK and would have been, or could have become, a British Citizen had your natural father been married to your mother at the time of their birth;
  • You were born before June 2006 outside the UK to a British father who was not married to your non-British mother.

In all three of these scenarios, we are assuming the British parents were born in the UK or were naturalised. Nowadays, people born in these three scenarios would be automatically British Citizens from birth.

Furthermore, it is possible that under the recent Nationality and Borders Act 2022, the correction of these historical inequalities may stretch back a further generation (I say “may” because the Home Office guidance on the subject is vague) and you may now be able to register as a British Citizen in the following scenarios:


  • You and your parents were born outside the UK, and at least one of your grandmothers is/was British but the relevant parent is/was not a British Citizen because women could not pass on British Citizenship to their children;
  • You and your parents were born outside the UK, and at least one of your grandfathers is/was British but the relevant parent is/was not a British Citizen because he was not married to your grandmother and unmarried couples could not pass on British Citizenship to their children.

People born in these scenarios would not be automatically British Citizens but for historical unfairness, but they would have the right to register. It remains to be seen if this will be the reality.
