Completing the application form
This page provides details on how to fill in the naturalisation application form AN. Before you fill in the application form you should read the information on eligibility to make sure you meet the requirements. If your application is rejected because you do not meet the requirements your fee will not be refunded.
You should fill in the form in block capitals using a black or dark-blue pen. Please enter all dates as dd-mm-yyyy, for example 29-04-2000.
If you would like help completing the application form you may use the services of a solicitor or other advisor. You should make sure the advisor you use is registered with the Office of the Immigration Services Commissioner (OISC).
If you would like to make sure you have completed your form correctly, many local authorities in the United Kingdom run a nationality checking service. For a small fee the authority will check your completed form, supporting documents and application fee before sending your application on to us for consideration.
The application form AN is split into six sections. Some sections of the form must be completed by everyone applying for naturalisation. Other sections should only be completed if they are relevant to your application. The information below highlights the most important parts of each section. A full guide on what is required in each section is provided in the leaflet naturalisation as a British citizen - a guide for applicants.
Section 1 - personal information
You should complete this section as fully as possible. If you are applying for registration at the same time as your husband, wife or civil partner you will need to complete separate application forms.
The information you provide in this section will be used on your certificate of naturalisation. You should make sure your name, place and date of birth are entered correctly and match the details shown in your passport or identification documents. You must note any discrepancies on page 13 of the application form. We are only able to change your certificate in exceptional circumstances.
If you are successful in your application you will need to attend a citizenship ceremony to be presented with your certificate. Ceremonies will normally be within a local authority near where you live. If you would like your ceremony in another area you should enter the name and address (including the postcode) of that local authority in part 1.19.

Convictions for criminal offences may become 'spent' after specified periods of time from the date of conviction if there are no further convictions during that time. Spent convictions will be disregarded for certain purposes. They will not normally be taken into account when assessing whether someone is of good character. Convictions that are not yet spent are known as unspent convictions and will be taken into account when assessing good character.
