Overview

UKVI has updated its Form MN1 guidance for registering children under 18 as British citizens. The guidance now reflects that applicants applying from within the UK can use the citizenship Priority Service, which became available from 20 July 2026. It also includes updated information on digital status, explains when a child becomes British, and updates the section on citizenship-related queries. The update does not change the legal routes or eligibility requirements for registering a child as a British citizen.

What changed in the latest version

These changes directly affect people who apply to register a child under 18 as a British citizen. They provide new information and make parts of the application process clearer. The guide now confirms that a priority service is available. This means applicants might now be able to get a faster decision, if they meet the conditions. This was not clearly stated before. The new part that explains 'when will the child become British?' gives important information. This can help families plan and manage what they expect. The updated guide on destroying Biometric Residence Permits (BRPs) ensures that people follow the correct steps after citizenship is approved.

Explained simply

Imagine you're trying to get a special club membership for your younger sibling who's under 18. This update is like the club changing its rulebook. Now, there's a 'fast pass' option if you want to get their membership quicker, which wasn't clearly stated before. The club also added a new page that clearly says exactly when your sibling gets their membership card. Plus, they're explaining how you'll get a digital membership instead of a physical one, and what to do with the old temporary ID card once they're official members. It just makes everything clearer and potentially faster for you and your sibling.
