How do I apply for naturalisation as a British citizen?
This section explains how to apply for naturalisation as a British citizen. To apply for naturalisation, you should use application form AN. Before you apply, you should ensure that you have read the section on eligibility. You must be aged 18 or over to apply for naturalisation. If you are under 18, you should read the section on registering a child as a British citizen. Before you make your application, you should read our guidance documents, Booklet AN and Guide AN. These provide full details of the requirements that you must meet, and how to complete the application form. You will need to confirm on the application form that you have read and understood both documents. You can download the documents as a single PDF from the right side of this page.
