Studying in the UK is a popular dream among Bangladeshi students, but the application process can seem complex.
Overview
Studying in the UK is a popular dream among Bangladeshi students, but the application process can seem complex. This blog post will explain everything students need to know about the CAS letter and the steps they need to take to get one.
What Is a CAS?

A Confirmation of Acceptance for Studies, also known as the CAS, is a unique 14-digit reference number from a UK university that confirms the student's admission and allows them to apply for visas.
The university issues this number after students have met all the conditions of an offer, like providing final grades and paying a deposit. A CAS number is also linked to a digital record held by the UK Visas and Immigration (UKVI), which contains a student's personal and course information.
What Is Included in The CAS?
The CAS letter for the UK is not just a number; it is a statement with all the important details the UKVI needs to know about the student. Bangladeshi students will also use this information to complete their visa application form.
A typical CAS statement includes:
- Personal Details: Student's full name, date of birth, nationality, and passport number.
- Course Information: The title and level of the course students will be taking, along with the start and end dates.
- Sponsor Information: The university's name and its UKVI sponsor license number.
- Course Fees: The total tuition fees for the student's first year, and any other fees that have already been paid.
- Academic Qualifications: The qualifications the university used in assessing the student's eligibility for the course, including the English language test scores.
How to Get a CAS Number?
The process of obtaining a CAS number is entirely at the discretion of the student's chosen UK university, as students cannot apply for one directly.
Here are the steps involved:
- Receive and Accept an Unconditional Offer: Students must first have a confirmed, unconditional offer from a university with a UKVI sponsor license. This means they have met all academic, English language, and other conditions.
- Pay the Deposit: Many universities require a tuition fee deposit to secure the student's place before issuing a CAS letter. This deposit amount is usually reflected on the CAS statement.
- The University Assigns Your CAS: Once students meet all the requirements, the university will create and assign a CAS number through UKVI's system and send the CAS statement to the students for verification and error correction.
CAS and Student Visa Application
A UK CAS letter and number are essential for the student visa application, and Bangladeshi students should take note of the following:
- Validity: A CAS number is only valid for six months from the date it is issued; therefore, students must submit their visa application within this timeframe.
- Application Form: When filling out the online Student Visa application, students should enter their CAS number for the UKVI system to pull up their digital CAS record.
- Matching Information: The information on the student's visa application must exactly match the details on the CAS statement to avoid visa refusal.
- Supporting Documents: The documents students provide to support the visa application must correspond with the qualifications and funds listed on their CAS.
Advantages of a CAS Letter
- A valid CAS number allows students to apply for and process a UK student visa.
- It serves as a student's official and verifiable confirmation of an unconditional offer at a UK university.
- The CAS letter is a comprehensive summary of all the information the UKVI needs to know about the students, the course, and their financial situation.
- The CAS is a digital document that the UKVI can access directly to speed up the verification process.
- A valid CAS number is worth 50 points and is the single largest component of the 70 points students need for a visa.

Frequently Asked Questions
- Can I apply for a CAS from more than one university?
No, a university can only issue you a CAS if they are confident you intend to study there, so you can only have one active CAS at a time.
- How long does it take to get a CAS?
The time it takes can vary, but once you have met all the conditions and paid any required deposit, it usually takes a few weeks. This process can be longer during peak application periods.
- Is a CAS number the same as an unconditional offer letter?
No, an unconditional offer letter is the formal document from the university stating that you have met all the requirements and have been accepted. A CAS number is a unique reference number issued by the university after you have accepted that unconditional offer and paid a deposit.
- What happens if my CAS expires?
A CAS is valid for six months from its issue date. If it expires before you submit your visa application, you will need to contact your university and ask them to issue a new one.
- What should I do if the information on my CAS is wrong?
You must contact your university's admissions or international office immediately. Do not submit your visa application with incorrect information.
