If you need to extend your visa to complete your studies, you'll need a CAS to support your Student Visa application

New Student route - Due to major changes in student immigration rules from 5 October 2020 with the introduction of the new Student route, the details on these pages may be subject to change. We are currently reviewing our web content but in the meantime, please refer to the UK government web pages for information on the new Student route.

The information on this page is relevant if you are a current student of the university, and want to extend your Student Visa to continue with an existing programme of study. If you need a visa for a new programme of study, please see our information about CAS for a new programme of study.

To prepare for your Student Visa extension, you should read our guidance on extending your student visa.

Due to the Covid-19 crisis, there are some changes to visa extensions at this point in time.

- Requests for a CAS for a short period of extension, for this academic year only, may not be approved by the university.

Please contact the International Student Advice Service if you have any questions about extending your visa.

What's in your CAS

A CAS (Confirmation of Acceptance of Studies) is an electronic document issued by the university and sent to you by email. In your CAS statement you will find:

  • Your CAS number
  • Information about your programme of study
  • Information about your tuition fees
  • Confirmation of whether you will need an ATAS certificate

How to get your CAS

To get your CAS, you need to complete the following steps:

Firstly, you need to prepare the following documents:

  • Bank statement or other financial document (click here for more information)
  • Birth certificate and consent letter (if you are using your parent's bank statement)
  • ATAS certificate (if applicable)
  • Entry stamp in your passport (if you are applying from outside the UK)

Please refer to our information on the documents you require for your visa application for more detail about these documents.

In order to ensure the new expected end date of your course is correct, first please discuss with your Faculty or Programme Leader before completing this section.

We will need to see your official results letter if you are repeating or deferring for the next academic session, and we cannot issue a CAS based on pending resit results.

If you are a student returning following an interruption of studies, the university will contact you in June/July, asking if you wish to resume your studies in September, and this will include instructions on how to apply for a CAS.

After this, complete our CAS request form, and send it together with your documents by email to t4compliance@greenwich.ac.uk. (Please note that this form works best in Internet Explorer).

If you submit your CAS request form to us without all of the required documents, we will not be able to process your CAS and you will need to resubmit your CAS request form again.

Once we have received your completed CAS request form and documents, we will aim to issue your CAS within four working days.

Check what funds you need

Please check the financial requirements for your Student Visa application. You will also need to know if your outstanding tuition fee balance for the current academic year.

  • You can check your fees by logging in to the student portal and going to 'check accounts, make online payment.'
  • If you are unsure about your tuition fees, you can check this with the Student Fees and Funding team or by visiting the Student Centre. You will need an accurate figure so that we can process your CAS request.

After your CAS is issued

Please check carefully that the information in your CAS statement is correct. It's important that the information you enter into your Student Visa application form matches your CAS statement.

If you need advice about your Student Visa application, please contact the International Student Advice Service who will be able to help you.
