Details

If you do not live in the Channel Islands, Isle of Man or a British Overseas Territory, you can apply online.

You can get help with your online application if you are in the UK and you do not have the appropriate access, skills or confidence to complete an online immigration application form.

Use this form if you now live in the Channel Islands, Isle of Man or a British Overseas Territory on or after 1 January 1983 and lived in the UK until you were 10 years old.

You can also use this paper form if you live elsewhere and want to apply by post. You will need to submit your documents with your application.

Most people who live in the UK and apply online are able to keep their documents while their application is processed.

You should read:

• the T guidance to check if you can apply
• the nationality forms guide to help you fill in the form

Send the form and payment slip (including the fee) and your documents to:

• the Lieutenant Governor if you are in the Channel Islands or Isle of Man
