When Hong Kong was transferred from the United Kingdom to China on 1 July 1997, all British Dependent Territories citizens (BDTCs) connected to Hong Kong lost their British nationality, unless they had applied for the British National (Overseas) (BN(O)) status. Most BDTCs of Chinese descent became Chinese citizens. BDTCs who did not become Chinese citizens and did not apply for BN(O) status while holding no other citizenship became British Overseas citizens (BOCs). As BN(O) and BOC statuses do not provide right of abode in the United Kingdom, BN(O)s and BOCs of non-Chinese descent who do not hold any other citizenship are "de facto" stateless. However, British nationality law allows BN(O)s and BOCs who are otherwise stateless to register for full British citizenship. In addition, the Chinese nationality law as applied in Hong Kong provides the option of naturalisation as a Chinese national.
