Applying to become a British citizen (naturalisation and registration)


Naturalisation is a legal process whereby someone with no automatic claim to British citizenship can become a British citizen and obtain the same rights and privileges as someone who was born a British citizen.

You can normally apply for naturalisation as a British citizen if you have lived in the United Kingdom or Islands for 5 years or more, or are married to a British citizen and have lived in the United Kingdom or Islands for 3 years or more.

Applicants must pass the Citizenship Test and meet the English Language Requirement. Further information: Citizenship Test and English Language Requirements


Registration is a legal process by which someone can gain British citizenship, or other British nationality status.

Registration as a British citizen is available only to people who already have specific connections to the United Kingdom or Islands, the British overseas territories, or Hong Kong.

Naturalisation and registration applications

All naturalisation and registration applications for Jersey residents are dealt with by the Jersey Customs and Immigration Service.

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