All Tier 4 applicants require a valid Confirmation of Acceptance for Studies (CAS) number to make an application. A CAS is a virtual document which confirms that an institution is willing to act as your educational sponsor. It provides the UKVI with your personal details and details of your course of study and can include details of any fees you have paid to the University. If you have received and accepted an unconditional offer from the Postgraduate Admissions Service, the admissions service will normally be responsible for assigning your CAS. For further information please refer to www.warwick.ac.uk/immigration/tier4/cas/
When will I receive my CAS?
You will receive an email regarding your CAS once you have an unconditional offer which you have firmly accepted. The email will be sent approximately three months before the start date of your course. It is important that you respond to this email as it asks you to confirm your personal details. We can not issue you with a CAS until you have responded to us.
How will I receive my CAS?
Once you have an unconditional offer that you have accepted and have responded to the email mentioned above, you will receive your CAS via email. You do not need a hard copy of this for your visa application. Occasionally, the visa application centre in your home country may ask for a hard copy of your CAS. In this case, please present a print-out of the email containing your CAS number.
