Confirmation of Acceptance for Studies (CAS) number and visa information
You need a CAS number to apply for a Tier 4 student visa. It is an electronic reference number and document that contains information about your course and your personal details. Your number is unique to you.
It is not a paper document.
You will be sent a CAS number once you have:
- received an unconditional offer
- paid your £1,000 online deposit.
