British Citizenship by Registration FAQS

January 1, 2026

British nationals can reside outside of the UK and still be considered British nationals. If you are a British national, you can register for citizenship. However, you cannot be a national or a citizen of another country to gain British citizenship through this route. 

There are different ways to apply, depending on how you acquired your British nationality:

  • If you have lived in the UK for 5 or more years
  • If you have worked as a Crown servant (diplomatic service, overseas civil service, armed services)
  • You have a connection with Gibraltar
  • Or you have lived in Hong Kong

More information can be found under the FAQs below. 

If you have lived in the UK or worked as a crown servant: 

  • You need to have lived in the UK for at least 5 years, spent no more than 450 days abroad during this time, and no more than 90 days in the last year. 
  • You must have worked as a Crown servant at any time.

You will need to provide supporting evidence as stipulated during your application. 

You have a connection with Gibraltar: 

If you were registered as a British overseas territories citizen in Gibraltar before 21 May 2002, you would have automatically become a British citizen. 

If you have a connection in Gibraltar, such as a grandparent or your parents were born/naturalised there, you can apply to register as a British citizen if either of these apply:

  • You were naturalised in Gibraltar after 21 May 2002 as a British Overseas Territories citizen
  • You were registered as a minor after 21 May 2002

You will need to get an application form from the Civil Status and Registration Office. 

You lived in Hong Kong:

You can register if you are a resident in Hong Kong at the date of application and:

  • You were ordinarily resident there on 3 February 1997
  • If you were born after 3 February 1997 and your parents were ordinarily residents in Hong Kong

Ordinarily resident means: you live in Hong Kong full-time, you are not breaking immigration laws, and you moved to Hong Kong voluntarily with the aim of settling there. 

You must be of good character to go this route.
