What you need to know...

The aim of this service is to help reduce unnecessary delays in the process of applying for British Citizenship by ensuring that your application meets the guidelines set by the Home Office.

The benefits of using this service:

  • application forms will be checked for completeness and accuracy
  • most important documents can be kept by the applicant
  • all applications are sent to the Home Office by secure registered post

Please note, this is not a fast track service - however, applications that are accurate and complete tend to be handled quickly and without further enquiry.

The Home Office Immigration and Nationality Directorate deals with each application on its own merit and it cannot be guaranteed that the Home Office will approve an application that has been checked using this service.

The Home Office reserves the right to request further documentation/proof at any time during the course of the application. Failure to disclose information will affect your application and may result in it being rejected.

Next steps

Please bring the following to your Nationality Checking Service appointment:

  • a completed application form for British nationality. Forms can be downloaded from the Home Office website - citizenship documents
  • all relevant documents that you are required to produce (as indicated in the application form)
  • the correct fee for the Home Office (as indicated in the application form). The fee for the Home Office is compulsory and must be paid by either credit card, debit card or a cheque.

You will also need to bring:

  • your Life in the UK Test Certificate
    AND
  • an English for Speakers of Other Languages (ESOL) certificate meeting Home Office standards and a covering letter from the college you attended, confirming that the course was conducted using citizenship materials and that you progressed from one level to the next. The college you attended must be accredited.

Please check that your ESOL course fully meets the requirements by visiting the Home Office website - ESOL with citizenship.

Approval of your application

If the Home Office approves your application for British Citizenship they will write to you and send you an invitation letter, which will inform you who you need to contact to book your Citizenship Ceremony.

Your details will also be sent to us. Once we have been notified that your application has been approved, we will automatically contact you with the next available group ceremony date.
