Switching to a Spouse Visa Inside the UK: Who Can Apply and How

If you are already in the UK on one type of visa and you marry or are in a qualifying relationship with a British citizen or settled person, you may not need to leave the UK to apply for the spouse/partner route. This is called switching — submitting a leave to remain application (FLR(M)) from within the UK rather than going abroad for an entry clearance application. But not every visa category allows switching, and the process has specific requirements.

Who Can Switch Inside the UK

The general rule is that if you are in the UK on a visa granted for more than six months, you are eligible to switch to the partner route. This includes:

• Work visas (Skilled Worker, Health and Care Worker, ICT, etc.)
• Student visas
• Graduate visas
• Family visas (switching from a dependant visa to the main applicant partner route)
• Tier 2 and Tier 1 visas (legacy routes)

Who cannot switch: If you entered on a Standard Visitor visa or a Short-Term Student visa (six months or less), you cannot switch in-country to the partner route. You must leave the UK and apply for entry clearance as a spouse/partner from abroad. This catches people out — particularly those who entered as a visitor intending to marry and then stay. The rules are explicit on this, and attempts to switch from a visitor visa will be refused.

If your leave has already expired or is about to expire without a valid application pending, you are in a more complex position that generally requires leaving the UK to apply.

How FLR(M) Differs from Entry Clearance

The FLR(M) application (Further Leave to Remain — Family) is submitted online via Gov.uk, and the core eligibility requirements are identical to an entry clearance application:

• £29,000 income threshold (or transitional £18,600)
• English language at A1 SELT
• Accommodation meeting Housing Act standards
• Genuine and subsisting relationship evidence

What changes in an FLR(M) application:

You can use joint income. Unlike an out-of-country entry clearance application where only the UK sponsor's income counts, an in-country FLR(M) applicant can combine their own income with the sponsor's, provided the applicant has permission to work in the UK. This can make a significant difference if the sponsor alone does not meet the threshold.

Cohabitation evidence matters more. If you are already living together in the UK before applying, the Home Office expects evidence of that cohabitation — joint tenancy agreement, council tax, utility bills in both names. The relationship evidence standard is the same, but you now have documentary proof of shared life in the UK to include.

Processing time is shorter. In-country applications take approximately 8 weeks on standard processing, versus 12 weeks for out-of-country applications. Priority (5 working days) and Super Priority (next working day) services are also available in-country via UKVCAS — Super Priority in particular is primarily an in-country feature not generally available for out-of-country applications.

Visa duration is 30 months, not 33 months (which applies to out-of-country entry clearance grants).

Fees are slightly lower. The in-country application fee is £1,407, versus £2,064 for out-of-country. The IHS for a 30-month visa is £2,587.50 for an adult.

The Biometric Appointment Process In-Country

After submitting the FLR(M) form online and paying the fees, you book an appointment at a UK Visa and Citizenship Application Services (UKVCAS) centre. Most supporting documents are uploaded digitally before the appointment, but you may need to present originals in person. UKVCAS charges a service fee that is separate from the Home Office application fee.

You must not travel outside the UK while your FLR(M) application is pending, unless you have taken specific advice about the implications for your status. Leaving with a pending FLR(M) can be treated as withdrawal of the application.

Maintaining Status While Switching

If your current visa expires while your FLR(M) application is pending, your status is protected by section 3C leave — a statutory provision that extends your existing conditions of stay until a decision is made on the application. This means your right to remain, and any work permissions you had, continue during the processing period. You do not become unlawful simply because your underlying visa expired after a valid in-time application.

The key is that the FLR(M) application must be submitted before your current leave expires. Do not wait until the expiry date to apply — processing delays can create complications if the application is late.

Common Questions About Switching

Can I switch if my employer is sponsoring my current visa? Yes. Applying for FLR(M) does not immediately invalidate a sponsored work visa — but once leave is granted on the partner route, your employer's sponsorship of your Skilled Worker or similar visa falls away. You will no longer need employer sponsorship to work, as the partner visa route has no employer restriction.

Does time on a different visa count toward the five years for ILR? No. The five-year clock for ILR on the partner route starts from when you are first granted leave on the partner route — whether that is entry clearance or in-country FLR(M). Time on a work visa, student visa, or other category does not count.

Can I switch from inside the UK if my partner is pre-settled? Yes. A pre-settled status holder qualifies as a sponsor under Appendix FM, provided their EU/EEA residence in the UK began before 1 January 2021.
