Most former CI holders were solely People's Republic of China citizens. Many of them were immigrants from mainland China who had acquired the right of abode in Hong Kong. They did not co-hold any type of British nationality. Before the handover, they were not eligible for any kinds of PRC passports. The PRC only issued Home Return Permit for them to enter mainland China only. If they did not choose to acquire British nationality through naturalisation, they could apply for the CI as a travel document from the colonial Hong Kong Government. Travel abroad was very difficult for CI holders, because CI was not a proof of nationality, in contrast with passport, thus rendering CI holders practically "stateless", even when most of them were Chinese nationals.. Most countries and territories required CI holders to obtain visas before travelling. After the handover, all Hong Kong permanent residents with PRC Citizenship are eligible to apply for a Hong Kong SAR passport.
Endorsements on CIs
On 1 July 1987, the concept of "right of abode" was introduced in Hong Kong legislation. A modified Hong Kong Certificate of Identity was introduced to ensure that Certificates of Identity would be acceptable for the purpose of international travel both before and after the handover of Hong Kong. These documents contain an endorsement showing that “the holder has the right of abode in Hong Kong”. To ensure Certificate of Identity will be acceptable for the purpose of international travel and for the return to HK after 30 June 1997, the British and the Chinese Government have agreed that the Certificate of Identity contain the following endorsement:
Acceptance and visa-free access
Countries that allowed Hong Kong Certificate of Identity holders to visit without visas:
After the HKSAR was established, a number of countries have ceased to accept CI's at different times. Those not yet eligible for HKSAR passports would recourse to the Document of Identity. However it is no longer possible to possess a valid CI as a travel document, because all CIs have expired by 30 June 2007.
