There are two ways to apply for British Citizenship – Naturalisation or Registration. The most common route for over 18s is Naturalisation. To apply for British Citizenship through this route, you will need to prove your English Language ability and pass the ‘Life in the UK’ test. You will also have had to live in the UK for at least five years and hold settled status for at least one.

The British Citizenship application is over 100 pages long and you cannot change any details or request a refund once it has been submitted. You will need to provide an extensive report of your immigration history, as well as evidence of your good character in your application.

What does British Citizenship mean?

Individuals with full British Citizenship are free to live, work and study in the UK. They can also travel out of it without being subject to the Immigration Rules. You can also vote and receive public funds once you have been naturalised.

The process for becoming a British Citizen will vary depending on your current status, the country you are from, your age and your situation at the time. For those applying for British Citizenship by marriage, there are also different requirements for British Citizenship applications.

What are the British Citizenship fees?

An adult applying for British Citizenship will need to pay:

  • £1330 for Naturalisation
  • £1206 for Registration

This fee covers both the Home Office fees and the Citizenship ceremony that you will need to attend once your application has been granted.

This payment is non-refundable and may vary depending on other specific circumstances, but it is one of the British Citizenship requirements.

What is Dual Nationality?

Once you have British Citizenship, you will most likely hold Dual Nationality. This will be the case unless your country of origin does not allow you to hold both nationalities. If you are a citizen of the United States, you will be able to hold both American and British nationality.

Your children will also be eligible for British Citizenship by birth and you can apply for a British passport.

Does my child have British Citizenship by descent?

A requirement for British Citizenship by descent if one or both parents is British at the time of the birth. If your child does not have the right of British Citizenship by birth, you may be able to register them as a British citizen. You can do this as long as one or both parents have gained settled status or British Citizenship since the birth.

This application is very extensive and will have its own set of requirements. For more information speak with one of our expert lawyers today.

How do I get British Citizenship by marriage?

There are many similar requirements for British Citizenship by marriage. The one key difference is that the spouse of a British citizen can apply for British Citizenship after three years’ residency. This is two years less than the usual requirements for British Citizenship.

Your application will also be dependent on your continuing relationship with your spouse.
