Nationality checking service

The Nationality Checking Service allows you to apply for British citizenship in person at one of our designated offices in Lancashire.

We will help you get your application right first time. Our Nationality Checking advisors have been trained and registered with the Office of the Immigration Service Commissioner.

Applying for British citizenship can be a difficult and lengthy process. The Home Office will return any application that is not completed properly or does not have the correct supporting documentation. Nine out of ten applicants that use the nationality checking service do not need to be contacted for any further information.

What we will do:

  • Check that your application is completed correctly
  • Certify all supporting documents and ensure they are correct
  • Ensure all required supporting documents are attached to your application
  • Return all original documentation back to the applicant
  • Send your application safely and securely to the Home Office using Royal Mail next day special delivery

What happens during the nationality checking service?

When you book an appointment we will send you more information on what to bring.  But in general you must:

  • Attend in person, if you are married or in a civil partnership and want to make a joint application, then both of you must attend in person.

Ensure you bring the following documents with you:

  • Completed up to date citizenship application form (AN) (MN1 for minors)
  • Original copy of your ‘Life in the UK’ test certificate
  • Original ESOL at entry level 3 or higher, or an equivalent level speaking and listening in English qualification, also include your college or test centre letter
  • All the listed documents in the application form guidance notes
  • The citizenship application fee.  Home Office fees may be paid by credit/debit card, postal order or cheque (made payable to ‘The Accounting Officer, Home Office').  We cannot send cash to the Home Office

Passport application service

We are now able to offer customers who go through the Nationality Checking Service a supplementary service that allows them to apply for a British passport at the same time as making the citizenship application.

At present the citizenship application and the subsequent passport application are completely separate processes. An application for a British passport can only be made once the nationality application has been decided and a citizenship ceremony has been attended. This two stage application process does mean a time delay between obtaining British citizenship and getting a passport.

Our new service, which has been developed in partnership with the Home Office, enables both applications to be submitted together. The passport application is held until the citizenship application has been decided and a ceremony attended. The passport is then released by HM Passport Office and is dispatched to the applicant’s home address shortly after the ceremony thereby making the whole process more efficient and easier for the customer.

The cost of this new service is an additional £10. Please contact us for an appointment on 0300 123 6705
