For Bangladeshi students planning to study in the United Kingdom, the CAS Letter is one of the most important documents in the entire student visa process. Without a CAS, you cannot apply for a UK Student Visa.

This guide explains what a CAS letter is, how the process works, what information it contains, and the key steps students must follow—especially applicants from Bangladesh.

What Is a CAS Letter?

CAS stands for Confirmation of Acceptance for Studies. It is an official electronic document issued by a UK university to confirm that:

• You have been offered a place in a course

• You have accepted that offer

• The university agrees to sponsor your UK Student Visa

The CAS is not a physical letter. It is an electronic record stored in the UK Home Office system. The student receives the details by email or through a university portal.

The most important part of the CAS is the CAS Number — a unique 14-digit code you must enter when submitting your visa application.

Why Is the CAS Letter Important?

You cannot apply for a UK Student Visa without a valid CAS. It serves several purposes:

• Confirms your admission into a licensed UK institution

• Provides all necessary academic, financial, and course details to UKVI

• Ensures your university is officially sponsoring your visa

• Includes your tuition fee payments and academic qualifications

In short, the CAS connects your university and the Home Office during the visa decision process.

Who Issues the CAS Letter?

Only universities and colleges listed on the UKVI Register of Licensed Sponsors can issue CAS letters.

Once you have met all admission conditions and paid the required deposit, the university’s visa or compliance team will generate your CAS.

When Do Students Receive the CAS Letter?

CAS is issued after you:

1. Receive an offer (Conditional/Unconditional)

2. Meet all academic and English requirements

3. Submit required documents

4. Pay the CAS deposit (varies by university)

5. Pass credibility or pre-CAS interview (if required)

After these steps, the university processes your CAS and sends it to you by email or via an online portal like CAS Shield, eVision, or MyHub.

Information Included in the CAS Letter

Your CAS contains all key information needed for your visa application, such as:

✔ Personal Details

• Full name

• Date of birth

• Passport number

• Nationality

✔ Course Information

• Course name and level

• Start and end date

• Course location / campus

• Academic progress justification (APEL/previous study explanation if applicable)

✔ Financial Information

• First-year tuition fee

• Amount already paid

• Scholarship (if any)

• Maintenance requirements

✔ Academic History

• Previous qualifications checked by the university

• English proficiency details (IELTS/WAEC/Medium of Instruction, etc.)

How the CAS Process Works (Step-by-Step Guide)

Step 1: Apply and Receive an Offer

You submit your application and receive either a conditional or unconditional offer.

Step 2: Fulfil Conditions

You provide missing academic documents, English results, or financial documents as requested.

Step 3: Pay the Required Deposit

Most universities require a deposit between £3,000–£8,000 before CAS issuance.

Step 4: Complete CAS Request Form

You will receive a link to update your passport details, previous visa history, address, and academic information.

Step 5: Attend a Pre-CAS Interview (If Required)

Many universities—especially for Bangladesh—conduct a credibility interview to ensure:

• You genuinely want to study

• You have the financial ability

• You understand your chosen course

Failing this interview may delay or prevent CAS issuance.

Step 6: CAS Issued

The university processes your information and issues your CAS Number.

Step 7: Apply for UK Student Visa

You use the CAS to apply for your visa within the valid timeframe.

How Long Is a CAS Valid?

A CAS is valid for 6 months from the date it is assigned.
Once used in a visa application, it cannot be reused.

Can a CAS Be Refused or Delayed?

Yes. Common reasons include:

• Incomplete documents

• Incorrect passport details

• Insufficient bank statements

• Compliance interview failure

• High immigration risk from your region or profile

• Late course enrollment or deadline missed

This is why it’s important to respond quickly and carefully during the CAS process.

Important Tips for Bangladeshi Students

✔ Double-check your passport, spelling, and academic details
✔ Keep your bank balance according to UKVI rules (28 days rule)
✔ Prepare for the pre-CAS interview
✔ Always meet university deadlines
✔ Keep copies of all tuition fee payments
✔ Respond to university emails immediately
