If you’re planning to study in the UK from Bangladesh, one of the most important documents you will need is the CAS Letter. Without it, you cannot apply for a UK Student Visa.

Yet many students and parents are still confused about what CAS is, how it works, and when they will receive it. This guide explains the entire process in simple, clear language — tailored specifically for Bangladeshi applicants.

What Is a CAS Letter?

CAS stands for Confirmation of Acceptance for Studies.

It is an electronic document, not a printed letter, issued by your UK university once you have officially fulfilled all requirements.

The CAS includes a unique 14-digit CAS Number that you must enter in your visa application. This number links your university admission with the UK Home Office system.

A CAS confirms:

• You have been accepted to a course

• The university is willing to sponsor your Student Visa

• Your documents and qualifications have been checked

• You have paid the required deposit

• Your English ability meets requirements (IELTS/PTE/MOI etc.)

As seen in the sample CAS letter above, you will find the following details covered in your CAS letter:

• 14-digit CAS reference number
• Course title and duration
• English language proficiency tests scores (like IELTS scores)
• Sponsor License Number (SLN) of your desired university
• First-year tuition fees or the entire course fee including scholarships if any
• Partial tuition fees paid to the university
• Partial accommodation fees paid

Why Is the CAS Letter Important?

You cannot apply for a Student Visa without a CAS.
It helps the UKVI verify:

• Your identity

• Your academic history

• Your course details

• Tuition fees and payments

• Sponsor licence details of the university

• English language qualification

In simple words: CAS is the gateway to your UK student visa.

When Do Students Receive a CAS?

Universities issue CAS only after you meet all conditions:

✔ Step 1 — Receive an offer (Conditional / Unconditional)

✔ Step 2 — Submit academic & English documents

✔ Step 3 — Pay the CAS deposit

✔ Step 4 — Complete CAS request form

✔ Step 5 — Pass the credibility / pre-CAS interview (if required)

✔ Step 6 — University compliance team approves the file

✔ Step 7 — CAS is issued and emailed to you

Bangladeshi students often require an interview due to high-risk classification.

What Information Does a CAS Letter Include?

Your CAS contains:

1. Personal Details

• Full name

• Date of birth

• Passport number

• Nationality

2. Course Details

• Course name

• Course level

• Start and end date

• Campus location

3. Financial Details

• First-year tuition fee

• Amount already paid

• Scholarship amount (if any)

4. Academic Details

• Qualifications verified by university

• English language proficiency

5. Sponsor Details

• University’s UKVI sponsor licence number

• Address of the campus

If anything is incorrect, your visa may be refused — so always double-check carefully.

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

Step 1: Accept the Offer

After receiving your offer letter, accept it formally.

Step 2: Pay the Required Deposit

Most universities require £3,000–£8,000 before issuing CAS.

Step 3: Submit Required Documents

These may include:

• Passport

• Academic certificates

• IELTS/PTE results

• Financial documents (if asked)

Step 4: Complete CAS Request Form

The university may send a link to portals like:

• CAS Shield

• eVision

• MyAccount

• MyHub

Step 5: Credibility Interview (if required)

You must clearly explain:

• Why you chose the UK

• Why this university

• Who is sponsoring you

• How you will afford living expenses

• Your career plans

Failing the interview can stop CAS issuance.

Step 6: CAS Issued

You receive your CAS by email with a 14-digit CAS number.

Common Reasons for CAS Delay or Denial

• Wrong passport information

• Incorrect academic documents

• Insufficient deposit/payment

• Weak interview performance

• Missing deadlines

• Doubts about financial capability

• Too many refusals in past visa history

Bangladeshi students often face stricter scrutiny — so accuracy matters.

Important Tips for Bangladeshi Students

✔ Maintain required bank balance for 28 days
✔ Double-check spelling, passport number, and dates
✔ Respond to university emails immediately
✔ Keep all tuition payment receipts
✔ Take the credibility interview seriously
✔ Follow deadlines strictly

Your CAS Letter Is Your Entry Ticket to the UK

A CAS letter is more than just a document — it is the final approval from your university allowing you to apply for the UK Student Visa.
