8. You have an ongoing application for another type of visa in the UK
9. In some circumstances, where have a debt in relation to your tuition fees

Funds you will need for your visa extension

Please check the financial requirements for your student visa application. To be able to get your CAS you will need to demonstrate the correct funds are in place to the university firstly.

• You can check your tuition fee amounts and status by logging in to the student portal and going to 'check accounts, make online payment.'
• If you are unsure about any aspect of your tuition fees, you can check this with our Student Finance team.

Documents needed as part of your CAS request

You should check if you need to provide any documents with your CAS request. This is particularly important if you are applying for a new CAS to return from interruption of study.

The following is a list of documents that may be needed before the university can issue you with a new CAS:

Financial documents

Please note that not all students are required to provide finance documents with their visa application:

• If you are a national from one of the countries listed under ST22.1 – Differential evidence requirement for a Student, you do not need to provide financial documents as part of your CAS/visa application. Please check this list carefully before submitting your request to us.
• If you are making your Student Visa application in the UK, and have been in the UK for at least 12 months with valid visa  then you do not need to demonstrate your finances as part of your CAS request or visa application.

If you do need to provide finance documents as part of your visa application, then you will need to provide them firstly to the university before a CAS is issued to you. Please see our webpages on Financial Requirements and How to demonstrate your finances, to find  useful guidance and examples of documents that can be used along with your application.

ATAS certificate (if applicable)

ATAS is a requirement that applies only to some programmes or areas of research.  See our guidance on ATAS for more information

Proof of departure from the UK for example, entry/exit stamps in your passport or boarding pass

Proof of departure from the UK will be requested if you have been required to make your new Student Visa application from outside the UK.  Proof of departure could be an entry stamp in your passport to your home country or boarding passes.

Completing and submitting the CAS request form

If you are in the UK and applying to extend your visa

Please complete an online CAS request form. Once you have completed this, the Student Visa Compliance Team will process your request.

If you need to provide additional documents with your CAS request, please send the documents separately to studentvisa@greenwich.ac.uk. Please include your student ID in your email.

Once you have completed the CAS request form, you can expect to receive a response within 10 working days.

What's in your CAS

A CAS (Confirmation of Acceptance of Studies) is an electronic document issued by the university. It contains a copy of information which has already been provided to UKVI from the university.

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

Your CAS will be sent to you by email, usually to your personal email address.

Once your CAS is issued

Please take a moment to check that all the information in your CAS statement is correct. If you spot anything that doesn’t look right, let us know straight away and  before you submit your visa application.  It is your responsibility to check the CAS statement carefully and inform the university of any incorrect information before using the CAS.
