British citizenship process
United Kingdom legislation
The British Nationality (Hong Kong) Selection Scheme, usually known in Hong Kong as simply the British Nationality Selection Scheme (BNSS), was a process whereby the Governor of Hong Kong invited certain classes of people, who were permanent residents of Hong Kong with the right of abode, and who were also considered British nationals under the British Nationality Act 1981, but were not British citizens (with the right of abode in the United Kingdom), to apply to be considered and then be selected to become registered as British citizens under the British Nationality (Hong Kong) Act 1990.
The scheme allowed at least 50,000 persons, and their spouses and children, to become British citizens by means of registration under the 1990 Act.
British nationals who were permanent residents of Hong Kong with the right of abode, who also met certain eligibility criteria, could apply to be selected to become registered as British citizens, under Section 1(1) of the 1990 Act, during two three-month periods: 
The Governor and the Government of Hong Kong retained the power to invite, accept, process and approve applications after 31 March 1994. However, no person could be registered by the British Home Secretary as a British citizen under that section of the 1990 Act after 30 June 1997.
Spouses and children of those who were granted British citizenship under section 1(1) could apply for registration under Section 1(4) of the Act. All applications from spouses and children for registration under s. 1(4) were required to be made on or before 31 December 1996.
Eligibility criteria.
To be considered for registration as a British citizen under s. 1(1), a person was required to be settled in Hong Kong and to be one of the following:
There were four classes of eligible s. 1(1) applicants:
Selection of persons in the GOC and DSC classes was primarily based on a "points system".
Applicants who, in addition to British nationality, held, claimed or possessed, voluntarily or involuntarily, nationality or citizenship of another country, other than (and excluding) the nationality of the People's Republic of China (PRC), were penalised in the points test, although it was not a bar to acceptance, selection and registration.
Spouses and children of family heads who registered under s. 1(1) were eligible for registration under s. 1(4) regardless of their nationality. However, a spouse who married the family head after that person was registered under s. 1(1) was required to be settled in Hong Kong on the date of the marriage to be eligible for registration under s. 1(4).
Nationality status.
Under subsection 2(2) of the British Nationality (Hong Kong) Act 1990, a BDTC who was successfully registered as a British citizen under BNSS automatically ceased to be a BDTC.
While the Act did not specify the loss of applicant's British National (Overseas) status, subsection 4(3) of the Hong Kong (British Nationality) Order 1986 specified that BN(O) status would be lost when the applicant ceased to be a BDTC. Hence, those who were registered as British citizens under the BNSS would only hold one class of British nationality.
Under Chinese nationality law and the respective explanations made by the Standing Committee of the National People's Congress, the British Citizenship acquired by Chinese nationals in Hong Kong through BNSS is not recognised. They are not entitled to British consular protection in Hong Kong and other parts of the People's Republic of China.
