What is a CAS and how does the CAS process work?
A CAS is the electronic reference your university issues that lets you apply for a Student visa. Each university runs its own pre-CAS process, so the steps are not identical everywhere. This guide explains the common pattern and flags what to check with your specific university.
What is a CAS?
CAS stands for Confirmation of Acceptance for Studies. It is a unique reference number, tied to your course and university, that you enter in your Student visa application. It confirms the university (a licensed sponsor) has offered you a place and is sponsoring your study.
How is a CAS issued?
Typically after you accept an unconditional offer, meet the university’s pre-CAS conditions and complete any required steps. Universities differ in exactly what they ask for before issuing CAS, so follow your university’s instructions precisely.
Are deposits or pre-CAS interviews involved?
Many universities ask for a tuition deposit before issuing CAS, and some run a pre-CAS interview or credibility check to confirm you are a genuine student and understand your course and funding. Whether these apply, and their form, depends on the university.
What errors and delays should I watch for?
Check every detail on your CAS — name spelling, passport number, course title, fees and any deductions — because errors can cause visa problems and take time to correct. Delays often come from outstanding documents or unpaid deposits; respond quickly to the university’s requests.
What happens after CAS?
Once you have a correct CAS you can submit your Student visa application with your financial and other evidence. The CAS is one required piece of the visa application, not the visa itself.
