If you are already in the UK on a valid visa, you may be able to apply to switch to or extend a UK Spouse Visa using Form FLR(M). This allows eligible partners of British citizens or settled residents to remain in the UK for 2 years and 6 months. This guide explains how to apply, what documents to prepare, and what to expect after submission — updated for October 2025.
Who Can Apply Inside the UK?
You may apply from within the UK if you currently hold a visa type that allows switching to the Spouse Visa route. Eligible applicants include those who:
- Hold a valid visa of more than six months’ duration (e.g., Skilled Worker, Student, or Graduate visa).
- Are married or in a civil partnership with a British citizen or a person with Indefinite Leave to Remain (ILR).
- Have not overstayed their current visa.
If you are outside the UK, refer to Applying for a Spouse Visa Outside the UK (2025).
Eligibility Criteria
All applicants must meet the core requirements under Appendix FM of the Immigration Rules:
- Relationship: Genuine and subsisting marriage or partnership.
- Financial: Minimum income threshold of £29,000 per year or sufficient savings.
- Accommodation: Adequate housing available without public funds.
- English Language: CEFR level A2 or above for in-country applications.
For details, see Eligibility Criteria (2025).
