UK Ancestry Visa / British National (Overseas) — BN(O)
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.

Ancestry Records
General Register Office (GRO) England & Wales, ScotlandsPeople, GRONI (Northern Ireland)
MODERATEThe UK Ancestry visa route requires proof that a grandparent was born in the United Kingdom. Applicants must obtain the grandparent's full birth certificate issued by the GRO (England & Wales), ScotlandsPeople (Scotland), or the General Register Office for Northern Ireland (GRONI). Birth registration in the UK has been comprehensive since 1837 (civil registration). The applicant must also prove their own birth certificate and the connecting lineage (parent's birth certificate linking them to the UK-born grandparent). No apostille is required for UK documents submitted in a UK Home Office application. Foreign documents (e.g., applicant's birth certificate from another country) may need certified translation into English. Note: "born in the UK" includes England, Scotland, Wales, and Northern Ireland; it does not include the Channel Islands, Isle of Man, or British Overseas Territories for the purposes of this visa.
Recent Changes
The UK Ancestry visa application fee increased to £637 per applicant (main applicant and each dependant). The Immigration Health Surcharge (IHS) is also payable: £1,035 per year per person (at 2024 rates). For a 5-year visa, the IHS component is £5,175 per person — a significant additional cost on top of the visa fee.
