CAS Guidance for Staff

Student visa overview

Since 2010, all students applying for a student visa from both within the UK and overseas require a Confirmation of Acceptance for Studies (CAS). Each CAS is unique and is issued to a student by the University as their Sponsor. The CAS is not a document but a unique reference number and is frequently known as the CAS number. The CAS is transmitted to the student by email in the form of a statement which includes other information that the University has transmitted to the UKVI.  On 5 October 2020, the Student visa replaced the Tier 4 (General) student visa.  The CAS requirement remains unchanged.

As the student’s Sponsor, the University makes a statement to the UK Visas and Immigration Service (UKVI) describing the students’ suitability for their course of study and lists the evidence which they have used to determine this. This information is recorded in Banner and uploaded centrally to the UKVI on a daily basis. The UKVI allocate the CAS which is recorded in Banner and then issued to the student by email.

Students cannot apply for a Student visa without having a valid CAS. In addition to the CAS, students may also need to provide the UKVI with the following evidence: an ATAS certificate (if applicable), a TB certificate (if applicable), and proof of funds (to cover the first year of their tuition fees and maintenance ie monthly living costs). The amount that a student needs to evidence for maintenance is set by the UKVI.  As part of their visa application, students must pay the Immigration Health Charge to access healthcare.

Key notes:

Joint CAS

Usually a CAS can only be issued for one course of study. A Joint CAS however is issued for the study of both a pre-sessional and substantive, or main, programme of degree study. A Joint CAS can only be issued if a student is 'unconditional firm' or 'unconditional accept' on their substantive programme of study.

The CAS Team exchange information with the UKVI each working day through the UKVI online Sponsorship Management System (SMS).
