CAS number applications

Off

International students (those from outside the UK) coming to study in the UK must be sponsored by an institution, such as the University of Sheffield, which is registered with the UK government's UK Visas and Immigration (UKVI) as an 'approved education provider' (this is not the same as financial sponsorship).

To confirm their sponsorship, anyone who applies for a visa to study in the UK must include with their visa application a unique Confirmation of Acceptance for Studies (CAS) number, linking them to the institution where they intend to study.

Arranging your CAS number

Arranging the CAS number is one of the tasks completed as part of your Pre-Registration at the University of Sheffield. You will be sent an email inviting you to begin Pre-Registration and giving you access to the Pre-Registration system when:

  1. You have accepted an Unconditional offer of a study place at the University; and
  2. It is less than four months before the start of your course.

The CAS Application task will appear in the Pre-Registration system when

  1. It is less than four months before the start of your course;
  2. You have accepted an Unconditional offer of a study place at the University; and
  3. You have paid any fee deposit we have requested (postgraduate taught applicants only).

The following table describes the process. Sections in bold text indicate where you need to do something.

Please be aware that when students are issued with a CAS number, they become subject to UKVI rules on monitoring International students. This means that we will have to report you to UKVI if you do not register at the University, or if you do not attend your course.
