What is a CAS?

International students applying for a Tier 4 Student Visa will need a Confirmation of Acceptance for Studies (CAS) number. This number confirms to UK Visas and Immigration (UKVI) that you have been accepted to study at a valid UK university. We generate a CAS by inputting all the necessary information into the UK Government Sponsor Management System. It is important that the information we input about you and your course is correct as we cannot change it once your CAS number has been generated by the UKVI (though we can add a Sponsor’s Note in exceptional circumstances). 

Once you have met a number of conditions, including accepting an unconditional offer, we will have the information we need to generate a CAS number for you. You will be sent a CAS statement that will confirm your CAS number as well as further details about your course, fees and the evidence we have used to assess your suitability for the course.

Please note: you do not need to have received your CAS statement before you start preparing for your Tier 4 visa application. The University’s International@CampusLife team have put together a comprehensive guide to Applying for a visa from outside the UK to help and support you with this.

Obtaining your CAS

Frequently Asked Questions

When will I receive my CAS?

The quicker that you complete the actions and provide the documents above, the quicker we will get your CAS to you. CAS statements can take up to 10 working days to be issued at busy times. However, provided that we have all the information we need from you to accurately complete the UKVI SMS system and generate a CAS, you can usually expect this to be significantly quicker.

Remember: you do not need your CAS to start preparing for your Tier 4 visa application.

Will I receive joint CAS?

Students can be sent a joint CAS covering a single pre-sessional English course and degree course. However, only students studying on the Level 2 or Level 3 pre-sessional courses are eligible. The criteria are as follows:

10 Week Level 2 Programme

  • Applicants cannot have an individual IELTS component score below 5.5; and
  • Applicants must be no more than 0.5 below the IELTS overall requirement and no more than 0.5 below in any two of the component requirements. Where 6.0 is required in each component applicants must also have achieved 6.0 in at least two of the components.

8 Week Level 3 Programme

  • Applicants cannot have an individual IELTS component score below 5.5; and
  • Applicants must meet the IELTS overall requirement, meet the Writing component requirement and be no more than 0.5 below any other component requirements; or
  • Applicants must meet each IELTS component requirement and be no more than 0.5 below the overall requirement


In addition to the above requirements, applicants must also have met the academic requirements for their chosen programme.

What is the deadline?

There is no specific cut-off date for issuing CAS statements. The deadline for submitting documents will depend on the latest enrolment date of your course, as well as the visa processing times in the country in which you are applying for your visa. Visa processing times for some countries can be located on the Home Office website.

However, we do strongly encourage you to send the required documents as soon as possible. This is to avoid any delays and give us sufficient time to process your application. Please note that CAS statement can take up to 10 working days from the date that all required documents have been submitted.

How do I apply for my visa?

The University’s International@CampusLife team has trained immigration advisors to help our students.

Do I need a Secure English Language Test (IELTS for UKVI)?
