1. What is a CAS?

The CAS (Confirmation of Acceptance for Studies) is an electronic document issued by your UK university or college to confirm that you have been accepted onto a specific course of study. It’s not a paper document but a unique reference number that is uploaded to the UK Home Office system.

Essentially, it’s your official proof of admission and serves as the foundation for your UK Student Visa application. Without a valid CAS, you cannot apply for your visa.

The CAS also ensures that your chosen institution is a licensed sponsor authorized by the UK Visas and Immigration (UKVI) to enrol international students.

2. Why is the CAS Important for UK Student Visa Applications?

The CAS is a critical requirement for the UK Student Visa (formerly Tier 4 Visa). It plays several vital roles:

• Confirms Your Admission: It verifies that you’ve been offered a place at a recognized UK institution.

•  Supports Your Visa Application: Your CAS number is mandatory when filling out your UK Student Visa form.

• Contains Key Course Details: It includes information about your course, tuition fees, and financial requirements.

• Validates Your Sponsor: It proves your university or college is an approved sponsor under the UKVI system.

Without a CAS, your visa application will be automatically refused — making it one of the most essential steps in your study abroad journey.

3. Who Issues the CAS?

The university or college where you have accepted an offer of admission is responsible for issuing your CAS. Only institutions listed on the UKVI register of licensed sponsors can provide this document.

Typically, once you have accepted your unconditional offer and paid any required deposit or tuition fee, your institution will begin processing your CAS.

Each CAS is unique and assigned only once, meaning you cannot reuse an old CAS or transfer it from one institution to another.

4. When Do You Receive the CAS?

Most universities issue the CAS around 3 months before your course starts, giving you enough time to apply for your visa.

The timeline may vary depending on:

• When you accept your offer

• Whether you’ve met all academic and financial conditions

• Your university’s internal procedures

Usually, universities issue a CAS statement via email, containing your unique CAS number and detailed course information.

5. Information Included in the CAS Letter

Your CAS letter includes a variety of important details that the UKVI uses to assess your visa application. These details must match your visa application exactly.

Here’s what the CAS letter typically contains:

• Your CAS number

• Your personal details (name, date of birth, nationality)

• Your course title and level

• Your course start and end dates

• The institution’s sponsor licence number

• Your tuition fees and any fees already paid

• Details of your English language proficiency

• Your previous education qualifications

• Information about scholarships or financial aid (if applicable)

Always check the information carefully to ensure there are no errors or inconsistencies, as mistakes could delay or affect your visa decision.

6. Documents Required to Get a CAS

Before your university issues your CAS, you’ll need to provide several documents to verify your eligibility and meet compliance requirements. These may include:

• A copy of your passport

• Academic transcripts and certificates

• Proof of English proficiency (IELTS, TOEFL, PTE, etc.)

• Proof of financial ability (bank statements or sponsor letters)

• Tuition fee payment receipt or deposit confirmation

• Offer acceptance confirmation

• Previous UK visa details (if applicable)

Some universities may also conduct a pre-CAS interview to confirm your genuine intent to study in the UK.

7. Step-by-Step Process to Obtain Your CAS

Let’s break down the CAS process step-by-step for clarity:

Step 1: Receive Your Conditional Offer

After applying to a UK university, you may receive a conditional offer requiring you to meet certain conditions such as exam results or English proficiency.

Step 2: Fulfil All Conditions

Submit all required documents and meet the academic or financial conditions outlined in your offer letter.

Step 3: Receive an Unconditional Offer

Once all conditions are met, the university issues an unconditional offer confirming your admission.

Step 4: Pay the Deposit

Many universities ask you to pay a tuition fee deposit before generating your CAS.

Step 5: Submit CAS Request Form

You’ll typically complete a CAS request form or provide additional information as instructed by your university.

Step 6: Verification by the University

The university verifies your details, including your academic history, financial proof, and compliance with UKVI requirements.

Step 7: Receive Your CAS Number

After successful verification, your university emails you the CAS statement containing your unique CAS number. You can now proceed to apply for your UK Student Visa.

8. Common Reasons for CAS Delays or Rejections

Unfortunately, not every CAS request is approved immediately. Here are common reasons for delays or rejections:

• Missing or incorrect documents

• Incomplete financial evidence

• Outstanding tuition payments

• Academic or compliance discrepancies

• Previous UK visa refusal or overstay

• Late submission of CAS request form

• Failing the pre-CAS credibility interview

If your CAS is delayed or refused, contact your university’s international admissions office immediately for clarification and next steps.

9. Tips to Avoid CAS-Related Problems

To make your CAS process smooth, keep the following tips in mind:

• Apply early to avoid last-minute delays.

• Double-check your documents for accuracy.

• Meet financial requirements before requesting CAS.

• Pay tuition deposits on time.

• Communicate regularly with your university’s admissions or visa team.

• Avoid providing false information — honesty is key for UKVI compliance.

• Keep copies of all submitted documents and your CAS letter.

10. Using CAS for Your UK Student Visa Application

When applying for your UK Student Visa, you must enter your CAS number on the online visa application form.

The UKVI will then use your CAS to verify:

• Your admission status

• Your university’s sponsorship

• Your course details

• Your tuition payments

• Your eligibility to study in the UK

A valid CAS can only be used once and expires six months after being issued. Therefore, apply for your visa within the validity period to avoid issues.

11. What Happens After Receiving the CAS?

Once you receive your CAS, the next steps are straightforward:

1. Check all information carefully for any mistakes.

2. Prepare financial documents for your visa application.

3. Book your visa appointment at the nearest VFS Global center.

4. Submit your biometrics and documents.

5. Wait for your visa decision from UKVI.

Once your visa is approved, you can start planning your travel, accommodation, and arrival in the UK!
