The UK Unmarried Partner Visa, also known as the "Unmarried Partner (Family) Visa," allows non-EEA (European Economic Area) nationals to join their unmarried partner who is a UK resident. The applicant must demonstrate that they have been living together in a genuine relationship akin to marriage for at least two years. The visa is initially granted for 30 months and can be extended for an additional 30 months. After five years, applicants can apply for indefinite leave to remain (ILR) and eventually British citizenship.
