What Is a CAS: The Key Document for a UK Student Visa
What a CAS (Confirmation of Acceptance for Studies) is for studying in the UK, when it is issued, what it contains and how it is used in your visa application.

Short answer: A CAS (Confirmation of Acceptance for Studies) is a unique reference number issued to you by your university. You cannot apply for a UK Student visa without it.
When is a CAS issued?
A CAS is usually issued after:
- you have received an unconditional offer or met all the conditions of your offer;
- you have paid any deposit the university requires;
- you have submitted the documents the university needs for the CAS (passport, language certificate, financial information).
Universities usually issue the CAS a few months before the course starts.
What a CAS contains
- your personal details and passport number;
- the course title, level, start and end dates;
- tuition fees and the amount already paid;
- the documents used to assess your admission (degree, language certificate);
- a note if ATAS clearance is required.
Check all the details as soon as you receive your CAS. If there is a mistake, ask the university to correct it before you apply for your visa.
Using your CAS in the visa application
You enter your CAS number in your Student visa application. You usually also need:
- your passport;
- proof of funds (for the remaining tuition and living costs, held for a set period);
- payment of the Immigration Health Surcharge;
- a tuberculosis (TB) test result if required.
Requirements and amounts can change, so check the current rules on gov.uk.
Important notes
- A CAS has a limited validity period, so do not delay your visa application.
- One CAS can be used for only one visa application.
- A pre-sessional course and the main programme may have separate or combined CAS numbers. See: pre-sessional course.
