Becoming a British citizen is a significant milestone. For most adults, the route is naturalisation after holding Indefinite Leave to Remain or settled status. Before applying, it is worth checking each requirement carefully, as the application fee is substantial and non-refundable.

Residence and absences

You will usually need to show a qualifying period of residence in the UK and that your absences during that period fall within set limits. Your travel history needs to be accurate and consistent with your previous immigration applications.

Knowledge of English and life in the UK

Most applicants need to show English language ability and pass the Life in the UK test. Some people are exempt because of age or a long-term condition.

Good character

The Home Office considers whether you meet the good character requirement. This can include immigration history, financial matters and other conduct. If anything in your history concerns you, take advice before you apply.

Children and registration

Many children can be registered as British citizens rather than naturalised, and some people are already British without realising it. Find out more about our citizenship service.
