What is a CAS and how do I get one?
A Confirmation of Acceptance for Studies is a reference number issued by a licensed sponsor once you have accepted an unconditional offer and met their conditions. It records your course, fees and payments and is required for a Student visa application.

Short answer: A CAS (Confirmation of Acceptance for Studies) is a 14-character reference your university issues after you accept an unconditional offer and pay any deposit. It is valid for six months and goes on your visa application.
What the university needs from you first
- Acceptance of an unconditional offer
- The tuition deposit, if the university requires one before issuing a CAS
- Copies of the qualifications and English evidence in the offer
- Passport details and, for some universities, a short CAS interview
What the CAS records
The course title, start and end dates, the fee for the first year, any amount already paid, how your English was assessed, and any work placement. Check every field: an error on the CAS becomes an error on the visa.
Timing
Universities issue CAS numbers in the months before the intake, typically from June for September starts. It is valid for six months, and you can apply for the visa up to six months before the course starts. Do not book flights until the visa is granted.
