Introduction
For many international students, finishing one course is not the end of their time in the United Kingdom. You may be moving from a bachelor’s degree to a master’s, continuing with a PhD, repeating part of your course, or completing a course that has been extended because of a work placement or study abroad period. In these situations, you may be able to stay in the UK through a UK student visa extension.
However, the important part is knowing whether your circumstances qualify, when you need to apply, and which documents you need before starting the application. For students considering an international student visa extension in the UK, these details can determine which requirements apply to their situation.
Can You Extend a UK Student Visa?
Yes, in certain circumstances, a student visa can be extended if you want to continue your existing course or move on to another course in the UK. This is the basis of an UK student visa extension for students whose studies continue beyond their current visa.
For this, you must already be in the UK on a Student or Tier 4 (General) visa and have an unconditional offer from a licensed student sponsor, confirmed through a Confirmation of Acceptance for Studies (CAS). For most students, the new course must show academic progression, meaning it is at a higher academic level than the previous course. At times, there are several exceptions, including resits or repeats, certain course changes following sponsor licence issues, PhD or doctoral study already begun under the previous visa, and some work placement or study-abroad situations. If your current visa was issued for less than 12 months, you may also need to prove that you have enough money for your studies and living costs.
Requirements for Student Visa Extension in UK
Before you apply for student visa extension UK, check that your new course and your circumstances meet the relevant requirements. These are the key requirements for student visa extension UK applicants need to consider before applying.
The main requirements include:
- You are currently in the UK on a Student or Tier 4 (General) visa.
- You have an unconditional offer from a licensed student sponsor.
- You have a valid CAS for the new course.
- You normally demonstrate academic progression.
- Evidence of sufficient funds.
- You meet any additional requirements that apply to your course or personal circumstances.
The new course must normally be at a higher level; however, a same-level course may also qualify if it is related to your previous course or career aspirations and is being studied at degree level or above at a higher education provider. Besides this, certain intercalated courses in medicine, dentistry or medical science are also covered by an exception.
The earliest you can apply is three months before the new course starts. Your application must be made before your current visa expires, and the new course must normally begin within 28 days of that expiry date. Your CAS must also still be valid, as it can only be used within six months of being issued. Meeting these requirements for student visa extension in the UK can help ensure the application is submitted within the permitted timeframe.
UK Student Visa Documents Checklist
The core checklist for an international student visa extension in the UK includes:
- Current passport or valid travel document: You will need to provide proof of your identity and a valid document for travel.
- CAS: Your Confirmation of Acceptance for Studies confirms your place on the new course and is issued by your institution.
- Evidence of finance, if needed: This might be required to demonstrate that you have enough money to cover your course fees and living expenses.
- ATAS certificate, wherever applicable: This depends on your nationality and your course.
- TB test results: Some applicants from some countries will need to submit results of a tuberculosis test as part of their application.
- Parental or legal guardian consent: This applies only to applicants under the age of 18.
- Proof of relationship, where required: Applicants under 18 may need to provide a birth certificate or other official document confirming their parents’ names.
- Written financial sponsor consent: This may be required if you had an official sponsor paying your fees or living costs in the past 12 months.
As part of an international student visa extension UK application, you may also be required to submit additional documents, depending on your individual circumstances.
Apply for Student Visa Extension in the UK
Once you have confirmed your eligibility and gathered the required documents, you can apply for a student visa extension in the UK online.
The application process requires you to prove your identity. Depending on your nationality, passport and circumstances, you may either use the UK Immigration: ID Check app with a UKVI account or attend a UKVCAS appointment to provide your fingerprints and photograph.
The application fee is £558 per person, in addition to the healthcare surcharge. There is no separate fee for providing your biometric information. You must ensure submitting the application before your existing visa expires. If you apply in time, you can remain in the UK while waiting for the decision.
UK Student Visa Extension Processing Time
The standard UK student visa extension processing time is usually 8 weeks. For anyone planning a UK student visa extension, this gives a useful indication of how long the decision may take. A faster decision may be available if UKVI tells you that you can use a faster service. However, an application can take longer if supporting documents need to be verified, an interview is required, or there are personal circumstances such as a criminal conviction.
During processing, avoid travelling outside the Common Travel Area because leaving can cancel your application. But if your application is successful, you will receive an eVisa and information explaining how to access it through your UKVI account.
Common Student Scenarios
- Moving from a bachelor’s degree to a master’s: This can demonstrate academic progression because the new course is at a higher level.
- Starting another related course at the same level: This may be possible where the course is related to your previous studies or career aspirations and meets the relevant higher education requirements.
- Continuing a PhD: Students who began a PhD or other doctorate under their previous visa may be able to extend without meeting the usual higher-level progression requirement.
- Resitting or repeating: The higher-level requirement does not apply in certain resit or repeat situations.
- Work placement or study abroad: An extension may be possible where studies have been extended because of a work placement or period of study abroad.
- Student Union Sabbatical Officer: Certain students completing their qualification after serving as a Student Union Sabbatical Officer may also fall under an exception.
Mistakes That Cause Refusals or Delays
A few avoidable errors can create serious problems with an application:
- Applying after your visa expires: This can make you an overstayer and lead to an automatic refusal.
- Missing the 28-day financial requirement: Where financial evidence is required, the funds must have been held for 28 consecutive days before applying.
- Using an expired CAS: A CAS is valid for six months from the date it is issued.
- Not fulfilling the academic progression requirements: If you are pursuing a new course, then you must meet the relevant progression rules unless it is exempted.
- Travelling when the application is still pending: Leaving the Common Travel Area cancels the application.
So, always check your eVisa for the exact expiry date before submitting your application and make sure your CAS and supporting evidence are valid.
