Apply for citizenship if you have a British parent

You were born on or after 1 July 2006

You’re automatically a British citizen if you were born outside the UK and all of the following apply:

  • you were born on or after 1 July 2006
  • your mother or father was a British citizen when you were born
  • your British parent could pass on their citizenship to you

Your British parent could pass on their citizenship to you if they were one of the following:

  • born or adopted in the UK
  • given citizenship after applying for it in their own right (not based on having a British parent)
  • working as a Crown servant when you were born (for example in the diplomatic service, overseas civil service or armed forces)

If you’re automatically a citizen, you can get:

If you’re not automatically a citizen

You may be eligible to apply for citizenship in one of these situations:

  • you’ve lived in the UK with your parents
  • your British parent lived in the UK before you were born
  • you were adopted outside the UK

If you’ve lived in the UK with your parents

You can apply if all of the following are true:

  • you’re under 18
  • your mother or father was a British citizen when you were born
  • you’ve lived in the UK with your parents for the 3 years before the date you apply

You must prove that you and your parents:

  • have not spent more than 270 days outside the UK during those 3 years
  • were in the UK exactly 3 years before the day the Home Office receives your application

If your parents are divorced or legally separated, only one parent needs to live in the UK with you. Both parents must consent to your application.

If your British parent lived in the UK before you were born

You can apply if all of the following are true:

  • you’re under 18
  • your mother or father was a British citizen when you were born
  • your British parent lived in the UK for at least 3 years before you were born
  • your British parent did not spend more than 270 days outside the UK during those 3 years
  • your British parent had a British mother or father who could pass on their citizenship to them

Your British parent’s mother or father could pass on their citizenship if they were one of the following:

  • born or adopted in the UK
  • given citizenship after applying for it in their own right (not based on having a British parent)
  • working as a Crown servant when your parent was born (for example in the diplomatic service, overseas civil service or armed forces)

If you apply this way, your children will not automatically become British if they’re born outside the UK.
