The UK De Facto Visa allows unmarried partners of British citizens or settled persons to live in the UK. To qualify, couples must prove they have been in a genuine relationship for at least two years and meet financial, accommodation, and English language requirements. This visa leads to Indefinite Leave to Remain (ILR) after five years. Applicants must provide strong evidence of cohabitation and commitment. The process involves submitting documents and attending a visa interview if required.
