Applying to become a British citizen

​​​​Naturalisation and registration applications

Jersey Customs and Immigration Service deal with all naturalisation and registration applications for Jersey residents.

The British Government is responsible for the laws covering British citizenship through the British Nationality Act 1981 (BNA) which applies to Jersey.

You need to meet certain rules before you can apply. These are available on the GOV.UK website. This guidance also applies to applications made in Jersey.

Becoming a British citizen by naturalisation or registration on the GOV.UK website.

Apply for naturalisation

You can apply for naturalisation if you:

  • have lived in the UK or Islands (Jersey, Guernsey or Isle of Man) for 5 years or more
  • hold indefinite leave to remain or settled status granted under the EU settlement scheme
  • hold indefinite leave to remain (ILR) and you must have lived in the UK or Islands for a period of 12 months or more after being granted ILR
  • meet the requirements of Knowledge of Language and Life

You may also be eligible to apply for naturalisation if you're married to a British citizen and:

  • have lived in the UK or Islands for 3 years or more
  • hold indefinite leave to remain or settled status granted under the EU settlement scheme
  • meet the requirements of Knowledge of Language and Life

You'll be naturalised in the same name and gender as it appears in your non-British passport. If you wish to naturalise using a different name and gender you must first change these details in your non-British passport. It is the same policy when applying for a British passport.
