If you’re planning to study in the UK, you’ve probably come across the term CAS Letter during your student visa process. It’s one of the most crucial documents required for your UK Student Visa application — without it, you can’t even apply for a visa.
What Is a CAS Letter?
CAS stands for Confirmation of Acceptance for Studies. It’s an official document issued by your UK university or college after you’ve received an offer and accepted it.
The CAS letter contains a unique reference number and important details about:
- Your personal information
- The course you’re enrolled in
- The university’s sponsor license number
- Your study start and end dates
- The tuition fees and payments made
This letter confirms that your university has officially accepted you as a genuine student, allowing you to apply for your UK Student Visa (Tier 4).
Why Is the CAS Letter Important?
The CAS letter plays a vital role in your visa approval process. Here’s why it’s so important:
- Proof of Acceptance:
It officially verifies that you’ve been accepted into a recognized UK institution. - Visa Application Requirement:
Without a valid CAS number, you cannot apply for a UK Student Visa. - Contains Key Visa Details:
The CAS includes essential details like your course duration, tuition fees, and sponsor details that the visa officer will cross-check. - Shows You’re a Genuine Student:
It proves that your chosen university has reviewed your profile and confirmed your eligibility. - Helps Avoid Visa Refusal:
A clear, accurate CAS letter minimizes errors and strengthens your visa application.
When and How Do You Get a CAS Letter?
You’ll receive your CAS Letter only after accepting your university offer and meeting all conditions, such as:
- Paying the required tuition deposit
- Providing valid academic and English proficiency documents
Once approved, the university issues your CAS number (usually via email).Most UK universities issue CAS 3–6 months before your course start date, giving you enough time to apply for your visa.
Documents You Need for CAS Issuance
To receive your CAS Letter, you typically need to submit:
- Academic certificates and transcripts
- English test results (IELTS, PTE, etc.)
- Passport copy
- Payment receipt (tuition deposit)
- Offer letter acceptance confirmation
Important Tips for Your CAS Letter
- Double-check that your name, date of birth, and passport number are correct.
- Ensure your tuition payment details are updated.
- Keep your CAS number safe and confidential — it’s unique to your application.
- Use your CAS within 6 months of issuance; otherwise, it will expire.
