If you need more time to complete your course, you may be eligible to extend your Student visa from within the UK. To qualify, you must be actively attending and engaging with your course.
Repeating with Attendance
As a taught student, you can apply for a visa extension if you're repeating modules that require on-campus attendance. This depends on when the repeated modules (including placements) take place. If there’s a gap of more than 60 days between your visa expiry and your next required attendance, you may need to leave the UK in the interim.
A CAS (Confirmation of Acceptance for Studies) will only be issued after we assess your academic engagement and progression. You cannot extend your visa if you're:
- Repeating without attendance,
- Only sitting exams or submitting coursework with no on-campus sessions.
Start the process by requesting a CAS Request Form from the Immigration & Compliance Team.
As a research student, if you've been granted extra time to complete your research, you may be able to extend your visa. Request a CAS at least three months before your current visa expires. We’ll review your attendance (e.g. campus swipes) and academic progress before issuing a CAS.
Please note, multiple extensions for the same course are unlikely to be approved unless clear academic progression is shown.
How to Apply to Extend Your Visa
- Continuing on the same course: Download and complete the CAS Request for visa extension (MS Word), then email it to your course admin team for initial approval.
- Starting a new course: You must make a formal online application. Your CAS will be issued by the International Admissions Team.
Our advisers can help you through your visa extension process, including completing the online application and responding to Home Office queries.
You can use our downloadable Guide to completing the student visa extension online form (Adobe PDF).
ATAS Clearance
If your course requires ATAS clearance, you’ll need a new ATAS certificate before your CAS can be issued. Apply at least 3–4 months before your visa expires, as processing times can be lengthy.
When You Cannot Extend Your Visa
You cannot extend your Student visa if:
- You have outstanding University debts.
- You're waiting for results to apply for a Graduate visa.
- You’re attending graduation (apply for a visit visa instead). See Graduation webpages.
- You’ve completed one course and are waiting to start another (with over 28 days between courses).
- You don’t meet the Home Office’s academic progression requirements.
- The extension would exceed your study time limit set by the Home Office.
Academic Progression
You must show academic progression to extend your visa in the UK. For example, if you have completed a master’s degree in the UK, you will not be permitted to study an undergraduate degree. Similarly, if you were unable to successfully complete the course for which your last student visa was granted, you cannot study another course on a new visa and must leave the UK to apply from overseas. The University will assess your eligibility before issuing a CAS.
Study Time Limits
The Home Office sets limits on how long you can study in the UK:
- Below degree level: max 2 years (age 18+).
- Degree level: max 5 years (with some exceptions, e.g. medicine, architecture).
- Postgraduate level and above: no time limit, but academic progression rules still apply.
For full details, see the UKCISA website.
