Confirmation of Acceptance for Studies (CAS)
for Continuing Students



If you are a current student at the University of Birmingham and you need more time to complete your course, you will need to apply for a Confirmation of Acceptance for Studies (CAS) number and use this for a Student Route visa application.

You must apply for your online CAS request up to three months before your visa is due to expire by completing the steps below.

Before a CAS can be assigned, the International Student Team (IST) will need to check that you have all the necessary documents to submit a Student Route visa application. 


New Students: You must contact the Admissions Team directly for your CAS. This webpage and CAS Request Form should not be used by new students who are due to commence a course. It is for continuing students only. 

An Expired Student Route Visa Vignette: Students outside UK who have been granted under the Student Route visa but whose 90 day visa vignette (sticker in passport) has now expired, must check if they can make an application to UKVI for a replacement visa vignette only. Further details about replacement visa vignette are explained here on UKCISA.

Study Time Limit Cap

There are no UKVI time limits on study at postgraduate level (RQF Level 7) and above e.g. Masters student, PhD student. These types of students do not need to complete this form as the UKVI time limit cap does not apply to your level of study. 

However, there are time limits ('caps') on how long you can study with a Student visa (this includes older versions e.g. Tier 4 visa) in the UK at either:

  • Study at degree level (e.g. Bachelors, RQF Level 6) = 5 year limit
  • Study at below degree level (e.g. RQF Level 5) = 2 year limit

For any time spent studying on a visa in the UK, while under the age of 18 is not to be counted in calculation. Time previously spent studying on the Student route (includes previously named Tier 4 visas) will be included in the calculation by the (UKVI) Home Office. Please note, there are only a few exceptions to the 5 year limit at degree level.

Please complete the form below if this applies to you.

Important Information - UKVI Differentiation Arrangements (Low Risk National)

Nationals of some countries do not need to provide evidence of their their money when they apply for a Student route visa. UKVI has named this as the "differentiation agreement" for " ‘low risk’ nationalities under the Student Route visa. You will need to refer to the UKVI list of nationals subject to different documentary requirements to see if your nationality is classed as ‘low risk'. If your country is on this list and you are applying from your home country or from the UK, then you will be classed as a low risk national. This means you will not be required to submit your financial evidence to UKVI (exceptions may apply if you are/have been in receipt of a official financial sponsorship).

If you have dual nationality and one of these nationalities is 'low risk', you can only be classed as low risk applicant, if you apply from that country and use this passport of that nationality for application. If you are a dual national, in this situation and you apply from a non-low risk country - you need to include your financial documents in your Student Route visa application.

However, you will still need to sign a declaration in your online CAS Request Form to confirm to the IST that you hold the necessary financial evidence. You must hold this evidence in the accepted format as the UKVI may request this evidence as part of their decision process later. UKVI will refuse your application later, if you are unable to provide it within a specified time frame.

For further details on the listed nationalities, you can also check the UK Immigration Rules that apply to the Student Route visa in ST 22.1 of the Immigration Rules ('Eligibility Requirements for a Student' - Scroll down to the last section for the list).



Continuing student with EU nationality - First CAS

Some EU nationals may need to request their first CAS from the IST, where they are a continuing student with no other visa permission to study in the UK. EU nationals who are classed as international students may need to apply for the Student Route visa, which will require a CAS. 

Please note, if you think you may be eligible for the EU Settlement Scheme or have been granted leave under this other visa route, then you should not require a CAS for Student visa purposes. Please read the UKCISA EU Settlement advice webpage for further advice. You will need to check if you need a UK visa if you’re planning to study in the UK from 1 January 2021 as normally you will not be eligible to apply for the EU Settlement Scheme unless you were living in the UK before 31 December 2020.




Step 2 - Submit your online CAS Request Form

Only one CAS Request Form submission is required, please do not submit duplicate requests.

When you complete your online form below, you will need to have your prepared visa documents for uploading in each required section that may apply to you. Upon assessment, the IST will contact you to request for further documents if you do not include all the required documentation which will cause further delays to the request processing time.

If you have submitted your request with all of the required visa documents in the correct format, the assessment of your CAS Request may be completed within 10 working days. If the IST requires any further documents or information, please allow for further processing time for IST to be able to complete our assessment. The IST has to prioritise CAS Requests based on urgency (if your visa is due to expire within the UK) as well the submission date.

Once you have submitted your CAS Request, you should receive an email from the IST confirming receipt of your CAS Request. The IST will then assess your documents and let you know if we require any further information. Please await our response.

Please do not send multiple chasing emails or CAS requests as this will delay the process.

What happens if my visa documents are not approved?

It is University Policy that you will not be assigned a CAS, if your visa documents do not meet the UK Visa and Immigration (UKVI) Student Route criteria.  If this happens your IST designated adviser will send you an email advising on your next steps.
