Visa requirements for British Nationals (Overseas)

Visa requirements for British Nationals (Overseas) are administrative entry restrictions by the authorities of other states and territories placed on British National (Overseas) passport holders. Several million people, the vast majority with a Hong Kong connection, hold this passport.
Holders of this nationality are British nationals and Commonwealth citizens, but not British citizens. This nationality, by itself, does not grant the right of abode anywhere in the world, including the United Kingdom or Hong Kong, but all BN(O)s possess either right of abode or right to land in Hong Kong due to holding right of abode before 1997. BN(O)s are subject to British immigration controls and do not have the automatic right to live or work in the United Kingdom. However, from January 2021, they will be eligible to apply for a five-year visa to work and study in the UK providing a path to citizenship, following the aftermath of the Chinese national security law imposed on Hong Kong, which the UK accused as a violation of the Sino-British Joint Declaration of 1984.
The British National (Overseas) status was created in 1985 in anticipation of the transfer of sovereignty of Hong Kong on 1 July 1997. This nationality was "tailor-made" for British Hong Kong residents with British Dependent Territories Citizen (BDTC) status by virtue of their connection with Hong Kong; it allowed the people of British Hong Kong to retain a relationship with the United Kingdom after the transfer of sovereignty of Hong Kong to China. BN(O)s enjoy consular protection as British nationals would when travelling outside Hong Kong. However, since most BN(O)s also hold Chinese nationality, they do not enjoy consular protection in China, Hong Kong and Macau, owing to the master nationality rule. From 1 July 1987 to 30 June 1997, nearly 3.4 million of British Dependent Territories Citizens in Hong Kong successfully registered as a British National (Overseas). All BDTCs relate only to Hong Kong lost their BDTC status on 1 July 1997, and any BDTC who did not register as a BN(O) and without other nationality automatically acquired British Overseas Citizenship.
Visa requirements for other classes of British nationals such as British citizens, British Overseas Citizens, British Overseas Territories Citizens, British Protected Persons or British Subjects are different.
Starting from 31 January 2021, China and the Hong Kong SAR governments no longer recognize the British National (Overseas) passport as a valid travel document.
