Following its transfer to Chinese sovereignty on 1 July 1997, Hong Kong was deleted from the list of British Overseas Territories. As a result, former residents of Hong Kong are not automatically qualifying Commonwealth citizens.
Only those previous residents of Hong Kong who hold a British Overseas Territories, British Nationals (Overseas) or British Overseas passport meet the nationality criterion for all elections in the UK. Any previous resident of Hong Kong who only has a Chinese Special Administrative Region passport is Chinese and may not register as a qualifying Commonwealth citizen. They may, however, be eligible to register as a qualifying foreign national.
