A Confirmation of Acceptance for Studies (CAS) is one of the most important documents required for a UK Student visa application. If you’re wondering what is a CAS letter for a UK Student visa, it is an electronic record issued by your university after you meet its admission and enrolment requirements. Without a valid CAS, Indian students cannot apply for a UK Student visa.
What Is a CAS Letter?
A Confirmation of Acceptance for Studies (CAS) is a unique reference number issued by a UK education provider that holds a Student sponsor licence. It confirms that the university has offered you a place on an eligible course and is sponsoring your Student visa application. Although many universities send a “CAS statement” by email, the key requirement for your visa application is the CAS reference number, which you enter in your online visa application.

Why Is a CAS Important?
The CAS allows UK Visas and Immigration (UKVI) to verify that you have an unconditional offer from a licensed student sponsor. A Student visa application cannot be submitted without a valid CAS reference number.
How to Prepare
- Accept your university’s unconditional offer.
- Complete all outstanding admission requirements.
- Check your CAS statement carefully for errors.
- Contact your university immediately if any information is incorrect before applying for your visa.
Common Misconceptions
A CAS is not an admission offer letter or a visa. It is an electronic sponsorship record issued by your university that enables you to apply for a UK Student visa.
Conclusion
Indian students receive a CAS after fulfilling their university’s admission conditions and any required pre-enrolment steps. The CAS reference number is a mandatory part of the UK Student visa application and should be checked carefully before submission.
