A UK Unmarried Partner Visa is a type of visa that allows non-EEA nationals to enter and remain in the UK as the unmarried partner of a British citizen or someone with settled status. To be eligible, applicants must demonstrate that they have been living together in a genuine and subsisting relationship for at least 2 years, meet the financial requirements, and pass an English language test. The application process can be complex and requires careful attention to detail. Successful applicants can stay in the UK for up to 2.5 years, after which they can apply for an extension or settlement. The cost of a UK Unmarried Partner Visa varies depending on the type of application and whether the applicant is applying from inside or outside the UK.
