The Nationality checking service is available in the UK for people applying for British citizenship, or British citizenship and a British passport at the same time.
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. Some local authorities can also accept and forward your British passport application to Her Majesty’s Passport Office (HMPO) at the same time you submit your application for citizenship.
They will ensure that your nationality or passport application form is correctly completed including supporting documents. They will not give you nationality or passport 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 the application. A passport will only be issued if you become a British Citizen. It is possible that that the Home Office may contact you for further information after your application has been submitted.
