CAS number application process

We have recently amended the process for arranging CAS numbers. CAS numbers are now arranged as part of your Pre-Registration with the University, using our Pre-Registration system. The new process is described below.

International students (ie those from outside the EU/EEA) 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 Home Office 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.

Please be aware that when students who have applied to study in the UK are issued with a CAS number, they become subject to Home Office rules on monitoring International students. This means that we will have to report you to the Home Office if you don’t register at the University, or if you don’t attend your course.

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, 1) when it is less than four months before the start of your course, and 2) when you have accepted an Unconditional offer of a study place at the University.

The following table describes the process of arranging a CAS number. Sections in bold text indicate where you need to do something. Please note that the process will only begin when you have activated your CAS Application via the Pre-Registration system. The CAS Application task will appear 1) when it is less than three months before the start of your course, 2) when you have accepted an Unconditional offer of a study place at the University and 3) (for postgraduate taught applicants only) when you have paid any fee deposit we have requested.

Stage What will happen Estimated time
1 The CAS Application task will appear on your Pre-Registration menu. Within 5 working days of you accepting an Unconditional offer of a study place at the University of Sheffield (and paying any associated fee deposit) or three months before the start of your course (whichever is later).
2 When you are ready to begin the process of applying for your CAS number, you should open the CAS Application task within the Pre-Registration system and follow the on-screen instructions to activate your CAS Application.
3 We will prepare the CAS Application Information about you that the Home Office requires before it can assign you a CAS number. When the CAS Application Information is ready for you to check, it will become visible within the CAS Application task. Within 1 working day of you activating your CAS Application.
4 You should check that all the CAS Application Information is present and correct (as it appears on your passport and other documents). If any information is missing or incorrect, you will be able to enter the correct information. When all the information is present and correct, you should confirm this by clicking the "Submit" button.
5 We will submit your CAS Application Information to the Home Office. Within 5 working days of you confirming your CAS Application Information.
6 The Home Office will process your information and, if it is all correct, they will allocate you a CAS number. They will send this number to the University (not to you). Within 1 working day of the Home Office receiving your CAS Application Information.
7 We will email you a CAS Statement confirming that your CAS number has been assigned and telling you what this is. You will also be able to view the CAS number, and the information we used in your application, by logging back in to your record in the Pre-Registration system. Within 2 working days of the Home Office sending your CAS number to the University.
8 After you have received your CAS number, you can find details of how to make your visa application on the Home Office website. Please note that you will only be able to apply for your visa a maximum of three months before the date your course is due to start.
