Nationality checking service

Where the nationality checking service is available in the UK for people applying for British citizenship or naturalisation.


  1. Documents

The nationality checking service is provided by local authorities (for example your county council or city council).

A local authority can accept and forward your application to UK Visas and Immigration.

The local authority will ensure that your form is correctly completed, and they will copy your documents and return them to you. They will not give you nationality advice.

The service is available by appointment only. Local authorities provide details of how much the service costs and the times appointments are available.

Local authorities that provide the nationality checking service must be registered with the Office of the Immigration Services Commissioner to legally provide the service.

Using the nationality checking service does not guarantee the success of your application. It is possible that the Home Office may contact you for further information after your application has been submitted.
