The UK unmarried partner visa allows non-married couples to reside in the UK if they meet eligibility criteria. Couples must prove a genuine, lasting relationship akin to marriage, including cohabitation proof for at least two years. The application process requires both financial evidence and intent to live together in the UK. Successful applicants can enjoy living with their partner and may later qualify for indefinite leave to remain. This visa category supports long-term relationships by providing a pathway for couples to build their life in the UK.
