British Naturalisation is the most common way by which a person with foreign citizenship can apply for British citizenship. If you are naturalised as a British citizen, you will be able to live and work in the UK without being subject to immigration control.

Unless you have a claim to British citizenship based on your ancestry (British citzenship by descent), you will need to apply for British Naturalisation on the basis that you have either spent 5 years in the UK lawfully, or 3 years in the UK as the spouse of a British citizen.


Step 1:Have lived legally in the UK for 5 years – you must not have been away from the UK for more than 450 days during that time, or 90 days during the last year

Step 2:Have held Indefinite Leave to Remain in the UK for at least 1 year at the time you make the application

Step 3: Be 18 years of age or over, pass the Life in the UK test, and Intend to have the UK as your main home.

Multiple Nationalities

UK nationality law allows you to have more than one nationality. However, you should check with the authorities of your original country before you apply for naturalisation, as some countries do not allow you to be a citizen of that country if you are a British citizen.
