Colonial era policy Hong Kong was a
British colony from 1842 until its
transfer to China in 1997. Accordingly, regulations on local residence rights were closely tied to
British nationality law during colonial rule. All
British subjects previously had unrestricted access to live and work in any British territory.
Parliament gradually restricted this from 1962 to 1971, when subjects originating from outside of the
British Islands first had immigration controls imposed on them when entering the United Kingdom. Hong Kong followed suit and imposed greater restrictions on subjects from outside the territory. British subjects born in the colony were given
belonger status, to indicate their possession of right of abode in Hong Kong.
Nationality law reform in 1981 reclassified the vast majority of Hong Kong belongers as
British Dependent Territories citizens (BDTCs). The border between Hong Kong and
mainland China was not regulated for over 100 years after establishment of the colony. Border controls did not exist until 1950, after communist victory in the
Chinese Civil War. Although the border was guarded, the Hong Kong government was relatively lax in deporting illegal immigrants due to a shortage of unskilled labour within the territory, allowing large numbers of them to register as residents. Still, colonial authorities held almost unlimited discretionary deportation powers over Chinese migrants until 1971, when those resident in the territory for more than seven years were given the
right to land. This exempted them from immigration control, though they could still be deported for serious crimes. Immigration became more restricted in 1974 at the start of the
Touch Base Policy. Under this system, illegal immigrants captured by law enforcement were immediately deported but those who had managed to reach urban areas of Hong Kong and found housing accommodation were given legal status. This policy ended in 1980, after which all free migration was stopped.
Transitionary arrangements The British and Chinese governments entered negotiations over the future of Hong Kong in the early 1980s and agreed on the
Sino-British Joint Declaration in 1984. The basic principles for the right of abode are set as part of this treaty and further defined in the
Hong Kong Basic Law in Article 24, which encompass the right to land with the added entitlement that a bearer cannot be deported. Belonger status was renamed
permanent resident status in 1987, when landed Chinese residents were given the right of abode along with Hong Kong BDTCs. All BDTCs who did not have a connection with a remaining
British Dependent Territory other than Hong Kong lost BDTC status on 1 July 1997. Former ethnic Chinese BDTCs became
Chinese nationals and could only retain British nationality if they had registered as
British Nationals (Overseas) prior to the transfer of sovereignty. Individuals who were not ethnically Chinese, had not registered as BN(O)s, and would have been stateless at that date automatically became
British Overseas citizens. Holders of CIs were able to replace them with
Hong Kong Special Administrative Region passports after the handover. == Acquisition and loss ==
