UK Ancestry Visa / British National (Overseas) — BN(O)
United Kingdom
The United Kingdom offers two distinct routes relevant to descent and heritage. The UK Ancestry visa allows Commonwealth citizens with a UK-born grandparent to live and work in the UK for 5 years, after which they may apply for Indefinite Leave to Remain and eventually naturalization as a British citizen. This is a temporary-to-permanent route, not immediate citizenship. The British National (Overseas) visa scheme is a separate, purpose-built route created in response to Hong Kong's political situation, allowing BN(O) passport holders and their close family members to live in the UK with a path to settlement and citizenship. Neither route grants immediate citizenship — both require lawful residency in the UK followed by the standard naturalization process. The UK does not have a general citizenship by descent program beyond the first generation born abroad to a British citizen parent.
