How long does British citizenship take?

Last reviewed 13 August 2026 · Reviewed by the BritainTest editorial team

Once you have met the requirements and applied, most people wait roughly six months for a decision on a naturalisation application, then attend a ceremony within three months. So the stretch from applying to becoming a citizen is often around six to nine months. This guide walks through the steps and the timing. It is general information, not immigration advice, and processing times change, so always check the latest on GOV.UK. For the requirements themselves, see our how to become a British citizen guide.

What happens after you apply

You apply online, then complete a few more steps: you attend an appointment to give your biometrics (fingerprints and a photo), provide your documents, and usually name referees who confirm your identity. The Home Office then reviews your application and carries out its checks before deciding.

How long the decision takes

The Home Office aims to decide most naturalisation applications within about 6 months. Some take longer, for example if more checks are needed or documents are missing. In some cases you may be able to pay for a priority service for a faster decision. Because published times change, confirm the current expectation on GOV.UK rather than relying on a fixed figure.

The citizenship ceremony

If your application is approved, you are invited to a citizenship ceremony and must attend within 3 months of the invitation. You legally become a British citizen at the ceremony, when you make the oath or affirmation of allegiance and the pledge and receive your certificate. Our citizenship ceremony guide explains exactly what happens.

The whole timeline

Putting it together, a typical journey is: apply → give biometrics and documents → about 6 months to a decision → invitation → ceremony within 3 months → British citizen. Plan around it, and do not book things that depend on being a citizen, such as applying for a British passport, until you actually have your certificate.
