Naturalisation As A Spouse Of A British Citizen

You can apply to naturalise as a British citizen if you are married to a British Citizen and you have Indefinite Leave to Remain (ILR) in the UK. An application for naturalisation as a spouse of a British Citizen is made using application form AN.

Eligibility Requirements For Naturalisation As A Spouse Of A British Citizen

If you’re married to, or the civil partner of, a British citizen, you can apply for naturalisation as British Citizen under section 6(2) of the British Nationality Act 1981 if:

  • you’re 18 or over
  • you’re of sound mind, you’re able to think and make decisions for yourself
  • you’re of good character, for example you don’t have a serious or recent criminal record
  • you’ve met the knowledge of English and life in the UK requirements
  • you’ve been granted indefinite leave to stay in the UK (this means there’s no specific date that you have to leave) or permanent residence if you’re an EEA national (and you have a permanent residence card or document that shows you have permanent residence)
  • you meet the residency requirement

Unless your spouse or civil partner works abroad either for the UK government or for an organisation closely linked to government, you must usually also have:

  • lived in the UK for at least the 3 years before your application is received
  • spent no more than 270 days outside the UK in those 3 years
  • spent no more than 90 days outside the UK in the last 12 months
  • not broken any immigration laws while in the UK

When applying under section 6(2) of the British Nationality Act 1981, the applicant is not required to wait 12 months after the grant of ILR before applying for British Citizenship. An application for British Citizenship can be made soon after the grant of ILR if your spouse is British Citizen.

Good Character Requirement For Naturalisation As A British Citizen

An applicant for naturalisation as a British Citizen must satisfy the good character requirement to succeed in his application. The British Nationality Act 1981 does not define good character. However, the Home Office UKVI guidance sets out the types of conduct which must be taken into account when assessing whether a person has satisfied the requirement to be of good character. Consideration should be given by the Home Office caseworker to all aspects of a person’s character, including both negative factors, for example criminality, immigration law breaches and deception, and positive facto

Two Referees For Naturalisation As A British Citizen

The naturalisation application Form (AN) requires an applicant to be supported by two referees. One referee must be a person of professional standing and the other must be the holder of a British citizen passport and either a professional person or over the age of 25.
