British National (Overseas), abbreviated BN(O), is a class of British nationality associated with the former colony of Hong Kong. The status was acquired through voluntary registration by individuals with a connection to the territory who had been British Dependent Territories citizens (BDTCs) before the handover to China in 1997. Registration for BN(O) status was limited to the 10-year period preceding the transfer as a transitional arrangement for colonial subjects; current residents cannot newly acquire this nationality.
