Colonial nationality arc (CUKC to BDTC to BN(O) to 1997 handover)
Citizenship in Hong Kong SAR
- Eligibility
- HISTORICAL (repealed/lapsed): Before the British Nationality Act 1981, HK residents were Citizens of the United Kingdom and Colonies (CUKC). The BNA 1981 (in force 1983-01-01) restructured CUKC status into British Citizen / British Dependent Territories Citizen (BDTC) / British Overseas Citizen; HK CUKCs became BDTCs by connection with the territory. BDTC-by-HK-connection lapsed on 1997-07-01 at handover. Cross-reference only (UK nationality law), allowlisted per HK scoping §7. HISTORICAL (closed): British National (Overseas) (BN(O)) was a UK nationality class created for HK BDTCs; the registration window opened 1987-07-01 and CLOSED 1997-12-31 (last date for those born in 1997 pre-handover); ~3.4 million BDTCs registered as BN(O) by 1997-06-30. BN(O) is a UK nationality class (BNA 1981), NOT an HK route, and is positively disconfirmed as an HK citizenship pathway.

Example scenarios
The person would have moved through the colonial nationality arc — originally a Citizen of the United Kingdom and Colonies (CUKC), reclassified as a British Dependent Territories Citizen under the British Nationality Act 1981, and then, at the 1997-07-01 handover, ethnic-Chinese Hong Kong residents became Chinese nationals under the PRC Nationality Law as applied via the NPCSC 1996 Explanations (Instrument 13).
