3. How to apply

There are 3 ways to apply for British citizenship by naturalisation:

  • make an individual application
  • use the Nationality Checking Service (NCS)
  • use an agent or representative

Make an individual application

You must fill in Form AN - application for naturalisation as a British citizen

Read the guidance notes and the requirements booklet, which tell you how to fill in the form and what other documents you need to provide.

Apply using the NCS

The NCS is run by local councils and they can help you make your application. Check if your local council has an NCS.

Apply through an agent or representative

An agent or representative is a private company or individual that can help you with your application and give you advice.

Check if an agent or representative is registered with the Office of the Immigration Services Commissioner (OISC).

You can also use some solicitors or barristers that aren’t registered with the OISC. These include:

  • General Council of the Bar
  • Law Society of England and Wales
  • Chartered Institute of Legal Executives
  • Faculty of Advocates
  • Law Society of Scotland
  • General Council of the Bar of Northern Ireland
  • Law Society of Northern Ireland

The Home Office will tell you when you need to provide your biometric information. Your biometric information is only held until you’ve attended a citizenship ceremony.
