Extending Your UK Visa: When and How to Apply

If you're in the UK on a valid visa and your circumstances have changed—or you simply need more time—extending your visa may be possible. But the process isn’t automatic, and timing is critical. Submit too late, and you risk overstaying. Apply incorrectly, and your extension may be denied. In this guide, we’ll explain who is eligible to extend a UK visa, when to apply, and how to prepare a successful extension application. Whether you’re a student, skilled worker, partner, or visitor, Outbound Visa can help you manage the complexities of extending your stay in the UK. Can You Extend Any UK Visa? Not all UK visas can be extended from inside the country. Here’s a general breakdown of who can and cannot apply for a visa extension: Visas commonly eligible for extension: • Student visa (if continuing studies or switching course) • Skilled Worker visa (if you’re extending employment) • Spouse/Partner visa (renewal toward Indefinite Leave to Remain) • Temporary Work visa (specific categories) • Innovator Founder visa • Parent of a child in the UK Visas typically not eligible for extension: • Standard Visitor visa (you must leave the UK and reapply from abroad) • Short-term study visa • Transit visas • Graduate Route visa (non-extendable, but may switch to other routes) 🟠 Disclaimer: Always check the conditions specific to your visa category. Extension rules vary, and UKVI policies can change. When Should You Apply to Extend Your UK Visa? Timing matters. You must apply before your current visa expires, and ideally: • No earlier than 28 days before the expiry date • No later than the day your visa ends (but don't leave it until the last minute) Once you apply, you can stay in the UK under the same conditions while your extension is being processed—even if your visa expires during that period. This is known as Section 3C leave. Avoid overstaying even by one day. It can impact future visa applications or cause a ban from re-entering the UK. For more on timelines, see our guide on UK visa processing times. What Are the Requirements to Extend a UK Visa? Requirements differ based on your visa type. But in most cases, you’ll need to provide: • A valid reason to stay longer (e.g. ongoing studies, employment, or family ties) • Proof of continued eligibility (like sponsorship, relationship, or course enrollment) • Updated supporting documents (bank statements, proof of address, biometric info) • Proof of lawful status in the UK (your current visa and BRP) 🟠 Every case is unique, and embassies may occasionally request documents not listed above. To avoid surprises, review the UK visa required documents checklist before applying. If you're unsure whether your case qualifies for an extension, it's best to consult a visa advisor—Outbound Visa can help assess your eligibility. How to Apply for a UK Visa Extension 1. Check If You’re Eligible Start by confirming that your visa type allows for extension and that your current status is still valid. 2. Gather Required Documents Prepare all updated and required documents, including: • Passport and BRP (if applicable) • Updated financial evidence • Proof of address in the UK • Evidence of continued sponsorship or family ties • Letter of explanation or cover letter For student and worker visas, your sponsor (university or employer) must also confirm that they are continuing your sponsorship. Learn more about sponsor obligations in our UK visa sponsorship overview. 3. Apply Online Most visa extensions are submitted through the UKVI website. You’ll fill in your application form online and pay the appropriate fees. 💷 Fees typically include: • Application fee (varies by visa type) • Immigration Health Surcharge (IHS) For an overview of costs, see our guide to UK visa fees. 4. Attend a Biometric Appointment You may be asked to attend a UKVCAS (UK Visa and Citizenship Application Services) appointment to provide fingerprints and a photograph. Some applicants may be allowed to reuse existing biometrics. 5. Wait for the Decision UKVI processing times vary. You may receive a decision within: • 8 weeks for most in-country applications • 5 working days or 1 working day with priority services (extra fees apply) Can You Work While Your Extension is Being Processed? If your previous visa allowed you to work, and you applied before it expired, you can continue working under the same conditions while waiting for a decision. However, if your visa did not permit work, you cannot begin employment just because you submitted an extension. What If Your Extension Is Refused? If your extension is refused, you may be required to leave the UK immediately or risk being classified as an overstayer. In some cases, you may be able to: • Request an administrative review (if applicable) • Reapply with stronger documentation • Switch to another visa route (if eligible) It’s essential to act quickly. Outbound Visa can help you evaluate your refusal letter and plan your next steps accordingly.
