A bno passport is a British National (Overseas) passport. British National(Overseas)Passport (English: BritishNational(Overseas)Passport, abbreviation: BN(O)), that is, the British National(Overseas) passport issued by the United Kingdom to Hong Kong residents. In response to the transfer of sovereignty over Hong Kong, the United Kingdom began issuing passports to Hong Kong residents with British national (overseas) status on July 1, 1987.
In the late 1970s, as the New Territories lease term was due to expire in about 20 years, the British government began negotiations on the future of Hong Kong. On December 19,1984, China and the UK signed a joint statement in Beijing. On the day of the signing, China and the UK exchanged memoranda on the nationality of Hong Kong residents respectively in the name of the Ministry of Foreign Affairs of the People’s Republic of China and the British Embassy in China. British National (Overseas) passport issued by the United Kingdom to Hong Kong residents after the handover of sovereignty on 1 July 1987.
British National (Overseas) Status is designed for those who have been granted British Dependent Territory citizenship by virtue of their links with Hong Kong. British National (Overseas) status has a transitional meaning compared to British Citizenship. The UK government does not grant the right of abode in the UK to BN(O) passport holders.
Heard a little better, BNO passports are just like the jade buildings in the air, look good, but in reality can not touch, since ancient times, the UK seems to have a rather strong resistance to immigrants, it is willing to welcome tourists from all over the world, but not willing to welcome “want to become British” tourists. So BNO passports don’t seem to be so popular.
