After students get the CAS, please check whether all the information on the CAS is correct, such as visa type or nationality, date of birth, surname, etc. If the information is wrong, it must be raised to the school so that the school can issue a new CAS. The information is correct and confirm the receipt with the school.

CAS replaced the original paper visa letter, and students only need to provide a CAS number to complete the UK study visa. Universities usually send CAS numbers to students by e-mail, so CAS is also called E-CAS. The validity period of CAS reference number is 6 months, and the number of CAS numbers issued by each British university is limited, so it is not easy to issue them to students.
