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.

Support and advice

As well as having a CAS number you must meet all the other requirements for a Tier 4 student visa.
