UK Citizenship & Naturalisation Translation Requirements
Last updated: March 2026
British citizenship — naturalisation — is the final step for most settled migrants. The application sits on Form AN. The documentation is lighter than spouse or ILR cases. Identity, marital status, and good character are the three main categories. Birth and marriage certificates not in English still need certified translations, even if you've been a UK resident for years and submitted them before.
What documents need translation for UK citizenship?
UK citizenship applications need certified translations of your birth certificate, marriage certificate (if it applies), and any identity documents not in English. Previous visa documents may also need translation if you haven't submitted them before.
Form AN asks three questions. Who you are. Your marital status. Whether you're of good character. Each translates into a small bundle of documents. Identity is usually the birth certificate plus passport. Marital status is the marriage certificate (and divorce decree if it applies). Good character pulls in any criminal-record certificates from countries you've lived in.
If you've been through an earlier UK application — initial visa or ILR — you may already have translations on file. They're still valid. UKVI does not need fresh translations as long as the original document hasn't changed. Including a clean copy with your citizenship application avoids any caseworker confusion.

How much does citizenship translation cost?
UK citizenship translation usually costs £25–£65. That covers a birth certificate, marriage certificate, and any extra identity documents. Each page costs £12.99.
Citizenship applications usually need fewer translations than visa applications. Most applicants need only their birth certificate and marriage certificate translated — usually 2–3 pages in total.
When should I order translations for citizenship?
Order translations before completing your Form AN application. Citizenship processing takes 6+ months. Submitting a complete application with all translations helps avoid further delays.
UK citizenship processing times are currently 6–12 months. Submitting a complete application with all required translations from the start helps your application move through the system without hold-ups.
