You may be eligible for a UK Dependent Visa if you are the spouse, civil partner, unmarried partner, or child of someone legally residing in the UK. The sponsor must hold a valid visa (e.g., Skilled Worker, Student) or have settled status. You must demonstrate a genuine relationship, intend to live together in the UK, and meet financial and accommodation requirements. Children must be under 18 and financially dependent. Each visa route has specific criteria, so always refer to the gov.uk website for detailed guidance.
