United Kingdom - Passport & Nationality - British National Overseas (BNO) - Upgrade to British Citizenship
Holders of a British National Overseas Passport (known as a BNO) who have no other citizenship or nationality, can be registered as a British Citizen. The BNO was created in response to the transfer of sovereignty of Hong Kong in 1997.
A British National Overseas citizen should NOT assume that simply because they hold nationality of another country, that they cannot upgrade their BNO status to full British Citizenship - this is because their other nationality MAY have been granted incorrectly and could be voided or cancelled.
A person will not qualify under this section if they have done anything AFTER 19 March 2009 that resulted in the loss of another nationality.
Other British nationality solutions involving Hong Kong include the following:
British Overseas Citizen (BOC) - Hong Kong (After 1 July 1997)
British Overseas Citizen (BOC) - Hong Kong (Before 1 July 1997)
British Citizenship by Descent (Hong Kong)
