• you made a declaration to give up citizenship of the United Kingdom and Colonies before 1 January 1983.
  • born, naturalised or registered in the United Kingdom; or

You have a right, only once, to register as a British citizen if you gave up your citizenship to keep or gain another citizenship.

• because you had reasonable cause to believe that your citizenship of a Commonwealth country would be taken away if you did not give up your citizenship of the United Kingdom and Colonies.

If you gave up your citizenship for any other reason, or have already given up and resumed British citizenship as a right, the Home Secretary may allow you to resume it, depending on the circumstances. You should contact us for advice before you make an application.
