Are you planning your UK study visa 2026? The CAS letter UK is a crucial university-issued proof that is necessary for your student visa application. As of the year ending March 2025, the Home Office UK granted about 403,497 sponsored study visas, highlighting how essential a timely CAS is.
Since the standard outside UK student visa decisions typically take around three weeks, getting your CAS letter early helps you hit the deadlines without worry. In this article, we will explore in detail the CAS letter UK for international students, what the requirements are, the processing, and further details.
What is the CAS Letter UK for International Students?
The Confirmation of Acceptance for Studies (CAS) letter is an essential electronic document that is issued by a UK university or institution to support your student visa application. It is mandatory for every international student to obtain a CAS letter from a licensed UK institution before applying for a student visa.
This is a mandatory requirement because a UK student visa is granted only after you accept your admission offer letter and pay the required deposit.
Typically, your CAS letter will mention the following:
- A 14-digit CAS reference number
- Your course title and duration
- English proficiency test scores like IELTS
- University's Sponsor Licence Number (SLN)
- Program tuition fee details (be it first year or full course fee, including scholarship, if applicable)
- Tuition fee payment confirmation (partial or full)
- Accommodation fee payment if applicable

What is the Importance of the CAS Number?
The 14-digit CAS number is unique for every international student individually and acts as a reference for UK Visas and Immigration (UKVI) to verify your enrollment at a UK academic institution.
All the details of the applicant are stored in a secure database which is accessible by both the university and UKVI, and during the visa application process, UKVI uses this number to cross-check applicant's information and ensure that you are a genuine international student.
