When you have successfully applied to become a British citizen you may not need to give up your present nationality to become a British citizen.

 

However, many countries do not allow dual nationality. If you become a British citizen and are a national of a country which does not allow dual nationality, the authorities of your country may view you as having lost your previous nationality or they may refuse to recognise your new nationality. Before you apply for British citizenship you should check your home country’s laws regarding dual nationality.

If you are in the UK and want to speak to someone about dual nationality you can contact the Home Office Nationality Quality and Enquiry Team.
