1. Executive Summary & Path to British Passport
Applying for British citizenship by naturalisation using Form AN is a separate nationality process for eligible adults who meet the statutory residence, immigration-status, language, Life in the UK and good-character requirements. For the standard route, applicants normally need to be free from immigration time restrictions for 12 months; that 12-month requirement does not apply to spouses or civil partners of British citizens.
2. Naturalization (Form AN) Requirement Matrix
The table below outlines statutory requirements for Form AN citizenship applicants:
| Requirement | Standard Naturalization (5-Yr Route) | Married to British Citizen (3-Yr Route) |
|---|---|---|
| UK Residence Duration | 5 years before application | 3 years before application |

4. Form AN Referees, Fees & Citizenship Ceremony
The current 2026 naturalisation fee is £1,709, with a £130 citizenship ceremony fee added, making the normal total £1,839. Once Form AN is approved, attend a citizenship ceremony and make the required oath of allegiance and pledge. You then receive your naturalisation certificate. A British passport is a separate application after citizenship has been granted; the naturalisation certificate itself cannot be used as a travel document.
