What is a UK CAS Letter?
A UK CAS Letter is an electronic document issued by a licensed UK university or college after a student accepts an unconditional offer.
CAS stands for Confirmation of Acceptance for Studies.
The CAS is not a physical certificate. Instead, it is a unique reference number generated by the university through the UKVI system.
This CAS number confirms that:
The university has officially accepted you
You meet the admission requirements
The institution is sponsoring your UK student visa
Your course is eligible under UK Student Visa rules
Without a valid CAS letter, you cannot apply for a UK Student Visa.
Why is CAS Letter Important for UK Student Visa?
The CAS letter is one of the most important documents in your UK student visa application.
The UK Home Office uses the CAS to verify:
Your university details
Your course information
Tuition fee information
Course duration
English language eligibility
Financial status
Immigration history
If your CAS contains incorrect information, your visa can be delayed or refused.
That is why students should carefully review every detail before submitting the visa application.
