Hong Kong Certificate of Identity Hong Kong Certificate of Identity The Hong Kong Certificate of Identity (CI; ) was a formal travel document and passport, issued by the Hong Kong Government's Immigration Department until June 30, 1997 (See transfer of the sovereignty of Hong Kong). It is no longer possible to possess a valid CI as a travel document, as all CIs have expired by 30 June 2007, though most CI holders should be eligible to hold the HKSAR Passport. Certificates of Identity were issued to Hong Kong permanent residents who did not hold and could not obtain any valid travel documents for overseas travel.

The lease consisted of the rest of Kowloon south of the Shenzhen River and 230 islands, which became known as the New Territories. The British formally took possession on 16 April
