Apply for British Citizenship

What is British Citizenship or Naturalisation as a British Citizen?

British Citizenship is either acquired by descent or through naturalisation. A British citizen by descent is either a person born in the UK, or born outside the UK if they have one British citizen parent. British citizenship, however, can also be acquired through naturalisation. Once you have gained British nationality, you can live and work in the UK legally and free from immigration controls.

The British Nationality Act 1981, which came into effect on 1st January 1983, defines how UK citizenship can be acquired and how an individual becomes a British citizen. It also defines how they give up their own citizenship of the country they belong to.

How to apply for British Citizenship

Becoming a British citizen is known as Naturalisation as a British Citizen. A citizen or a national of another country can apply for a visa for entry in the UK in several ways. If the candidate was issued a British passport on or after 1st January 1983, they are considered to be a British citizen.

You can apply for Naturalisation as a British Citizen after you have lived as a resident in the UK for 5 years. This is reduced to 3 years of residence or if you’re in a civil partnership with or married to a British citizen.

After your Naturalisation as a British Citizen application has been approved, you will receive an invitation to attend a Citizenship ceremony, at which you’ll be given your Certificate of Naturalisation. You can then apply for a British passport. This is usually processed within six weeks, although the Home Office may need to interview you while processing your UK naturalisation application.
