You can extend a Student visa in the UK if you are already in the UK with eligible Student or Tier 4 permission, you have a valid Confirmation of Acceptance for Studies, and you meet the Student route requirements. The key point is timing: you must apply before your current visa expires, and your new course must normally start within 28 days of your existing permission ending.
A Student visa extension is not just a formality. UK Visas and Immigration will look at your course, sponsor, academic progress, finances, English language position and documents. A small error, such as using an old CAS or applying with incomplete bank evidence, can cause avoidable problems.
If you are unsure whether your new course, resit, placement or further study qualifies, Immigration UK can help you understand the requirements and prepare a stronger, better organised application.
What Does Extending a Student Visa Mean?
Extending a Student visa means applying from inside the UK for further permission to stay under the Student route. This is usually because you are starting a new course, continuing your current course, repeating part of your studies, completing a work placement, or needing extra time for a doctorate or other eligible study.
This is different from switching into the Student route from another immigration category. Some people use the words 'extend' and 'switch' as if they mean the same thing, but the Immigration Rules treat them differently. For example, Visitors and Short-term Students generally cannot switch into the Student route from inside the UK.
It is also different from applying for the Graduate route. If you have successfully completed an eligible UK course and do not need further Student permission, the Graduate route may be more suitable. If your long-term plan is employment in the UK, you may also want to compare study options with routes such as the UK work visa route.
Who Can Extend a Student Visa in the UK?
To extend your Student visa, you normally need to be in the UK and hold current Student or former Tier 4 (General) permission. You must have an unconditional offer from a licensed student sponsor and receive a valid CAS before you apply.
The CAS is not simply an offer letter. It is an electronic record issued by your university, college or other licensed sponsor. It confirms important details such as your course, start and end dates, fees, academic level, English language assessment and sponsor information. Your CAS must usually have been issued no more than six months before your application.
If you are applying for a Student visa for the first time, or want a broader overview of the route, Immigration UK's study visa guidance explains the main eligibility requirements and application stages.
The Academic Progress Requirement
Academic progress is one of the most common areas of confusion in a Student visa extension. In simple terms, UKVI wants to see that your further study is genuine academic progression, not simply a way to remain in the UK without a proper study reason.
In many cases, academic progress means moving to a higher academic level, such as from an undergraduate degree to a master's degree. In some circumstances, a course at the same level may still be acceptable, but your sponsor will usually need to confirm that the new course is related to your previous study or supports your genuine career plans.
There are also situations where an exception may apply. These can include resitting examinations, repeating modules, completing a PhD or doctorate, taking an approved work placement, studying abroad as part of the course, or returning after a Student Union Sabbatical Officer period. Sponsor licence problems and certain medical or dental intercalated courses can also raise specific issues.
Your sponsor should reflect the relevant academic progress position on the CAS. If the CAS is unclear, do not assume UKVI will work it out for you. Ask your sponsor to correct or clarify the position before you apply.
When Should You Apply?
You should plan your Student visa extension around three dates: your current visa expiry date, your new course start date and your CAS issue date. Getting these dates wrong can make an otherwise good application invalid or risky.
You can usually apply no earlier than three months before your new course starts. You must apply before your current permission expires. Your new course must normally begin within 28 days of your current visa expiring. Your CAS must also usually be no more than six months old when you use it.
For example, if your current visa expires on 30 September and your new course starts on 20 October, the 28-day timing rule may be satisfied. If your new course starts in December, you may need to discuss options with your sponsor because the gap may be too long for an in-country extension.
If you submit a valid, in-time application, you can generally remain in the UK while UKVI decides it. However, your existing conditions still matter. Do not assume that applying gives you unlimited work rights or permission to start any course outside the Student route rules.
Financial Requirements for a Student Visa Extension
Not every student extending in the UK needs to submit bank statements. If you have lived in the UK with valid permission for at least 12 months on the date of your application, you will generally meet the financial requirement without having to provide funds evidence.
If the 12-month exemption does not apply, you may need to show money for outstanding course fees and living costs. The current maintenance figures in the Student route are £1,529 per month for study in London and £1,171 per month outside London, usually for up to nine months. Course fees paid to your sponsor may reduce the amount you need to evidence if they are correctly recorded or supported.
Where financial evidence is required, the 28-day rule is important. Funds normally need to be held for a continuous 28-day period, and the final day of that period must usually be within 31 days of the application date. One day below the required balance can be enough to cause trouble, which is the immigration equivalent of losing your umbrella just as it starts raining.
Some applicants benefit from differential evidence arrangements, meaning they may not need to submit financial documents automatically. Even then, UKVI can ask for evidence later, so it is sensible to have it ready before applying.
Documents You Should Check Before Applying
Your online application will generate a personalised document checklist. You should follow that checklist carefully, but most Student visa extension applications involve a similar set of core and conditional documents.
- Current passport or other valid travel document.
- CAS reference number from your licensed student sponsor.
- Financial evidence, if you are not exempt from showing funds.
- English language evidence, unless your sponsor has assessed this in an accepted way.
- ATAS certificate, where your course requires one.
- Written consent from an official financial sponsor, if required.
- Parental consent and relationship evidence if you are under 18.
- Evidence relating to qualifications used to obtain your offer, if requested.
Check that your CAS includes the correct personal details, course title, course level, start and end dates, tuition fees, payments made, study location and academic progress statement. If anything is wrong, ask your sponsor to amend it before you submit the application.
How to Apply for a Student Visa Extension
The application is made online from inside the UK. You should use the official Student visa extension process and answer every question consistently with your CAS and supporting documents.
- Confirm that your sponsor is licensed and your course qualifies.
- Request your CAS and check every detail carefully.
- Confirm whether you meet academic progress or an exception applies.
- Check whether financial evidence is needed and prepare it early.
- Complete the online application before your current visa expires.
- Pay the application fee and Immigration Health Surcharge.
- Prove your identity using the app if invited, or attend a biometric appointment.
- Wait for the decision and do not travel outside the permitted area.
You will need to pay the inside-UK Student visa application fee and the Immigration Health Surcharge. Students and Student dependants are charged the student IHS rate, but the exact total depends on the length of permission granted. Fees can change, so always check the amount shown during the live application before paying.
Student applications made inside the UK usually take around eight weeks, although complex cases can take longer. If timing is important, see Immigration UK's guide to UK visa processing times for practical context on delays and service standards.
Can You Travel While Your Extension Is Pending?
You should not travel outside the UK, Ireland, the Channel Islands or the Isle of Man while your Student visa extension is pending. If you leave this area before a decision is made, your application may be treated as withdrawn.
This can be frustrating, especially if you have family plans or a holiday booked. However, the safest approach is to avoid international travel until you receive your decision and can access your new eVisa. The official GOV.UK guidance on extending a Student visa confirms the application timing, fee, processing and travel position.
Dependants and Student Visa Extensions
Dependants are not automatically allowed with every Student visa extension. Current rules are more restrictive than they used to be, especially for courses starting on or after 1 January 2024. New dependants are generally limited to certain government-sponsored students and students on qualifying postgraduate research courses, such as PhD, doctorate or research-based higher degrees.
Existing dependants may have continuation options in specific circumstances, but each dependant must apply separately and before their current permission expires. They will also pay separate visa fees and Immigration Health Surcharge amounts. If your partner or child is applying with you, check their eligibility independently rather than assuming your extension automatically covers them.
Common Mistakes to Avoid
Many Student visa extension problems are preventable. The most common mistakes are usually practical rather than dramatic, but they can still lead to refusal or delay.
- Applying after the current visa has expired.
- Using a CAS that is too old, inaccurate or not yet issued.
- Ignoring the 28-day course start rule.
- Assuming an offer letter is enough without a CAS.
- Failing to meet the academic progress requirement.
- Providing bank statements that do not cover the full 28-day period.
- Missing ATAS, sponsor consent or English language evidence.
- Travelling abroad while the application is pending.
- Assuming dependants qualify under old rules.
If your application is refused, you may be able to request administrative review where you believe UKVI made a caseworking error. The refusal notice should explain whether this is available, the deadline and how to apply. Administrative review is not a fresh application and it does not guarantee a different outcome, so it is worth getting advice quickly if the decision affects your studies or immigration status.
Frequently Asked Questions
Can I extend my Student visa after it expires?
You should apply before your current visa expires. A late application can create serious immigration status problems and may affect your ability to continue studying in the UK.
How early can I apply for a Student visa extension?
You can usually apply up to three months before your new course starts. You must also make sure your CAS is valid and your new course normally begins within 28 days of your current permission expiring.
Do I need bank statements if I have been in the UK for more than 12 months?
If you have lived in the UK with valid permission for at least 12 months on the date of application, you will generally meet the financial requirement without submitting bank statements. UKVI can still ask for evidence in some circumstances, so keep documents available.
Can my partner or children extend with me?
They may be able to extend if they meet the dependant rules, but eligibility is restricted and each dependant must apply separately. The rules are particularly limited for many taught master's courses under the current dependant policy.
What happens after my Student visa extension is approved?
You will usually receive digital immigration status through an eVisa. Check your decision carefully, including the expiry date, course details and work conditions, and keep copies of your CAS and decision records.
