Key facts

  • You need to have lived in the UK lawfully for 5 years, or 3 years if married to or in a civil partnership with a British citizen, without excess absences; the 3-year route allows no more than 270 days abroad in the period and 90 in the final year.
  • You must be free from immigration time restrictions on the date of application and for at least 12 months before, unless married to a British citizen; indefinite leave to remain meets this.
  • You must pass the Life in the UK test and show knowledge of English at B1 CEFR or higher via a Home Office approved test or qualifying degree or nationality.
  • You must intend to make the UK your future home (unless married to a British citizen) and be of good character.
  • The 450-day absence limit appears in the registration guidance (Guide B2), not standard naturalisation; check the current naturalisation guide for the 5-year limits.
