Give up (renounce) British citizenship or nationality

Resume your British nationality

In some cases it’s possible to resume your British nationality after renouncing it.

Apply using form RS1. Read the guidance before you apply.


Pay the current fee for registration.

Your fee won’t be refunded if your application is refused.

Supporting documents

You’ll need to send:

  • your copy of your declaration of renunciation (either form RN1 or R6)
  • your passport, or certificate of naturalisation or registration for your current citizenship or nationality
  • an official letter or statement from the country you’re currently a citizen or national of saying that if you hadn’t given up your British citizenship you’d have lost or failed to get your current citizenship or nationality

If you gave up United Kingdom and Colonies citizenship you’ll also need to send:

  • the birth, naturalisation or registration certificate of the person you have the connection to the UK with, and evidence of your relationship to that person, eg a birth, marriage or civil partnership certificate
  • evidence that you gave up citizenship because you believed you’d be deprived of your citizenship of a Commonwealth country unless you did so - this should be a separate letter explaining this plus any supporting documents

You may have to provide different documents if you originally gave up citizenship for a reason other than you’d have lost or failed to get citizenship of another country - read the guidance for details.

Biometric information

You must also provide biometric information (fingerprints and a photo). This costs £19.20.

The Home Office will tell you when you need to provide your biometrics. Your biometric information is only held until you’ve attended a citizenship ceremony.
