naturalisation as british citizen process

There are three main ways of becoming a British citizen:

  1. Automatic acquisition at birth
  2. Registration (usually for children) and
  3. Naturalisation (usually for adults)

Naturalisation is the legal process by which a person changes their nationality. For hundreds of years, foreign nationals living in the UK, and sometimes living abroad, have been able to attain British citizenship through naturalisation.

The criteria and process have changed over the years but for successful applicants the end result has been the same: that person is granted the same legal rights and status of a natural-born British citizen.

Married to British Citizen:

As settled status is a simpler and faster process, an application for settled status followed by an immediate application for citizenship is the best course of action for anyone who is married to a British citizen and has lived in the UK for over five years.

Not married to British Citizen:

If you are not married to a British citizen but you needs to show that you are free from any immigration restrictions for at least one year before applying for naturalization as a British Citizenship.
