What is the Nationality Checking Service?
The Nationality Checking Service (NCS) was set up to help ensure that your citizenship application is properly completed and submitted with all the relevant supporting documents. Our advisers are trained and registered to check and forward your application. They will photocopy and certify your passport and other valuable documents so they remain in your safekeeping and send your application and correct fee to the Home Office by special delivery post.
Using the NCS is entirely optional and just gives you greater freedom of choice. You can apply directly to the Home Office yourself or use a solicitor or other agent.
