Form RS1: applying to become a British citizen again after renouncing

The Form RS1 guidance on gov.uk covers people who renounced British citizenship and want to apply to become British citizens again.

Written by ImmigrationGPTPublished 31 October 2026Source (opens in a new tab)

The gov.uk Form RS1 guidance covers people who have renounced British citizenship and now want to apply to become a British citizen again. It is the page to read if you are asking whether that application is open to you.

The guidance is about returning to British citizenship after renouncing it. It does not deal with first-time applications for citizenship.

The page on gov.uk is the place to check the conditions, fees and processing times for this application. Read the Form RS1 guidance on gov.uk (opens in a new tab) for those details.
