What documents do I need to apply for British Citizenship?

The following documents should be submitted with all British Citizenship (naturalisation) applications:

  • Proof that you are settled in the UK e.g. biometric residence permit (BRP) or permanent residence card
  • Proof that you meet the knowledge of life and language in the UK requirements
  • Evidence of identity e.g. valid passport, valid travel document or birth certificate. If a document was used as proof of identity for the Life in the UK or English language tests, this must be submitted with the application
  • Proof of residence in the UK for the relevant period (this will be for either 3 or 5 years, depending on whether you are married to a British citizen)

Additional documents may be required if you are applying on the basis of your marriage to a British Citizen or service to the crown.
