Information you will need for your application

Your Confirmation of Acceptance for Studies (CAS) number is your unique reference number which you will need to include in your visa application. Your CAS will be emailed to you and is not required in paper copy.

The CAS email will include:

• your personal details
• the qualification upon which your offer was based
• details of your course
• our address
• our sponsor licence number: NB0C74WCX

To get your CAS email you must have:

• passed all your exams and sent us copies of your qualifications or transcripts
• accepted an unconditional offer for a course at Cardiff University
• paid your deposit (if applicable)
• checked that all the information on your CAS email is correct.

Before you are sent your CAS, we will email you and ask you to check that all the details on your CAS are correct on the Online Applicant Service. Make sure the following are correct:

• your personal details - for example, that your name is exactly as it appears on your passport
• all the details of the qualifications shown in the evidence section of the CAS
• details of the course that you are coming to study at Cardiff University
• course duration
• any tuition fee payment that you have made to the University is recorded on the CAS.

Your CAS email must not be more than six months old when you apply for your student visa. If you use it after this date, your application will be refused.

If you haven't received your CAS

You will not be emailed your final CAS until you have checked your CAS online. Take time to check your CAS carefully and make the corrections on the Online Applicant Service (SIMS online).

It takes time to change your CAS after it has been issued, and your visa application could be delayed or even rejected if your CAS is wrong. No changes can be made to the CAS once your visa application is submitted.

If you require any changes or have any questions at this stage, please contact the Student Visa Compliance Team via our web form.

This must be completed online. Select 'Student Visa'.

To read the guidance notes and download paper application forms, visit the GOV.UK website.

For your Student visa application, you will need to submit your transcripts, exam certificates, and references showing that you have satisfied the entry requirements for your course at Cardiff University.

Your CAS will list the qualifications you need to submit.

If any of the documents (for example, references, qualifications, transcripts, and bank statements) you are submitting are not in English, then you must also include a fully certified translation by a professional translator.

You need to show that you have a certain amount of money to cover your tuition fees and living costs in order to get a Student visa.
