How to Get a CAS Letter from a UK University: A Complete Guide
If you are planning to study in the United Kingdom, receiving your Confirmation of Acceptance for Studies (CAS) is an important step in preparing your Student visa application. A CAS confirms that a licensed student sponsor has accepted you for a particular course and assigned you a reference number for your visa application.
However, receiving a university offer does not automatically mean that your CAS will be issued immediately. You may need to meet offer conditions, provide supporting documents, pay a required tuition deposit, or complete additional checks before the university can assign your CAS.
This guide explains what a CAS is, who needs one, how to obtain it, and what to check before applying for a UK Student visa.
What Is a CAS Letter?
CAS stands for Confirmation of Acceptance for Studies. It is an electronic record assigned by a UK university or other eligible student sponsor for a student visa application.
Students commonly refer to it as a CAS letter, although the CAS itself is an electronic record rather than a traditional paper letter.
The CAS contains a unique reference number and information about your course and sponsorship. The university provides the relevant CAS details so that you can use them when completing your Student visa application.
A CAS is not a visa and does not guarantee visa approval. You must still meet the applicable immigration requirements.
Who Needs a CAS to Study in the UK?
Most international students applying for a UK Student visa to study an eligible course need a CAS from an appropriately licensed student sponsor.
The university must be eligible to sponsor the relevant student, and the course must meet the applicable requirements.
If you are applying from Bangladesh, Pakistan, Ghana, or another country outside the UK, check your immigration route and course eligibility before beginning the process.
Students applying under other immigration routes may have different requirements, so a CAS is not necessary for every person studying in the UK.
When Can a UK University Issue a CAS?
A university usually considers issuing a CAS after you have received an offer and met the relevant conditions. The exact process varies by institution, course, and applicant.
Depending on your circumstances, you may need to complete the following steps:
Accept your university offer.
Meet academic and English language conditions.
Submit the required documents.
Pay the tuition deposit or other amount required by the university.
Complete any required pre-CAS checks or assessments.
Provide financial or other supporting information requested by the university.
Confirm that your passport and personal details are accurate.
Not every university requires the same steps. Follow the instructions provided by your admissions team and respond to requests before the relevant deadlines.
Step-by-Step Process to Get a CAS from a UK University
Step 1: Apply to a Suitable University
Start by choosing a university and course that match your academic qualifications, English language ability, budget, and career goals.
Check the entry requirements before submitting your application. This can help you avoid delays caused by missing qualifications or unsuitable course choices.
Step 2: Receive and Accept Your Offer
After assessing your application, the university may issue a conditional or unconditional offer.
A conditional offer means you still need to satisfy one or more requirements. These could include submitting final academic results, meeting English language conditions, or providing additional documents.
Read the offer carefully and follow the instructions for accepting your place.
Step 3: Meet All Offer Conditions
Before assigning a CAS, the university may require evidence that you have met the conditions of your offer.
Depending on the course and institution, this may include:
Final academic certificates and transcripts
English language test results or accepted alternative evidence
A valid passport
Additional academic or professional documents
Evidence requested during the university's assessment process
Submit clear, accurate documents and make sure your personal information matches your passport.
Step 4: Pay the Required Tuition Deposit
Some universities require an initial tuition payment before issuing a CAS. The amount and payment deadline depend on the university and programme.
Before paying, confirm the deposit amount, payment method, refund policy, and any conditions that apply if your visa application is refused.
Keep your payment receipt because the university may ask for evidence of the transaction.
Step 5: Complete the Pre-CAS Process
Some universities conduct additional checks before assigning a CAS. These may include a document review, financial assessment, or pre-CAS interview.
A pre-CAS interview is not a universal requirement. The process depends on the university and your individual circumstances.
If an interview is required, be prepared to explain:
Why you chose the UK
Why you selected the university
Why the course matches your academic background
How the course supports your career plans
How you intend to pay for your studies
Where you plan to live during your studies
Answer honestly and make sure your responses are consistent with your application documents.
Step 6: Complete the CAS Request
Once you have met the relevant conditions, the university may ask you to complete a CAS request form or provide additional information through its student portal.
Review every detail carefully, including your name, passport number, course title, course dates, tuition fee, and any payments recorded by the university.
If you notice an error, contact the university before using the CAS details in your visa application.
Step 7: Receive Your CAS Details
If the university is satisfied that you meet its requirements and can be sponsored under the applicable rules, it may assign your CAS.
The university will provide the CAS reference number and relevant information according to its process. Keep these details safe and check that the information is accurate.
You can then use the CAS details when preparing your UK Student visa application.
Documents Required for a CAS
There is no single document checklist that applies to every UK university. Requirements depend on your course, qualifications, circumstances, and the university's procedures.
Commonly requested documents may include:
Valid passport
Academic certificates and transcripts
English language test results, where required
Evidence of meeting offer conditions
Tuition deposit payment receipt, if applicable
Additional documents requested by the university
Financial evidence, where requested as part of its checks
Previous immigration or visa documents, where relevant
Some universities may request additional evidence even after issuing an offer. Submit only genuine documents and contact the admissions team if you are unsure what is required.
How Long Does It Take to Receive a CAS?
There is no fixed processing time for every university. The time required depends on how quickly you meet the offer conditions, submit the required documents, complete any checks, and satisfy the university's CAS procedures.
Delays may occur if:
Documents are missing or unclear.
Final academic results have not been received.
English language requirements remain outstanding.
The university is waiting for a deposit.
Additional verification or an interview is required.
Personal details need to be corrected.
To reduce delays, submit complete documents as early as possible and respond promptly to university requests. If your course start date is approaching, contact the university to ask about your application status.
What Is the Difference Between a University Offer and a CAS?
A university offer confirms that the institution is willing to admit you, subject to any conditions stated in the offer.
A CAS is a separate sponsorship record used for an eligible Student visa application.
Receiving an offer does not automatically mean that you have a CAS. You may still need to meet outstanding conditions and complete the university's required checks before the CAS can be assigned.
Likewise, receiving a CAS does not guarantee that your Student visa will be approved. The immigration authority assesses your visa application under the rules that apply to your circumstances.
What Should You Do After Receiving Your CAS?
Once you receive your CAS details, review them carefully before applying for your Student visa.
Check Your Personal Information
Make sure your name and passport details are correct. Contact your university promptly if you notice any errors.
Review Your Course Details
Check the course title, start date, end date, tuition fee, and any payments recorded in the CAS information.
Prepare Your Financial Evidence
Determine which financial documents you need to provide under the current Student visa rules. The requirements may depend on your circumstances and any applicable exemptions.
For applications subject to the standard maintenance requirement, the amounts applicable in October 2026 are £1,529 per month for study in London and £1,171 per month outside London, for up to nine months. This equals £13,761 and £10,539 respectively.
These amounts are immigration financial requirements, not a guarantee that the money will cover all your actual living expenses. You may also need to demonstrate that any required unpaid tuition fees are covered.
Prepare Your Student Visa Application
Complete the relevant application form, provide the CAS reference number, and prepare the supporting documents required for your circumstances.
Check the current application fee, Immigration Health Surcharge where applicable, biometric or identity-verification requirements, and any additional instructions.
Plan Your Travel Carefully
Do not assume that a CAS alone allows you to travel to the UK for study. Make sure you understand the applicable visa process and have the necessary permission before travelling.
Common Reasons for CAS Delays
Students can often avoid unnecessary delays by preparing carefully.
Incomplete documents: Check the university's checklist before submitting files.
Unmet offer conditions: Confirm that all academic and English language requirements have been satisfied.
Incorrect personal details: Ensure your name, date of birth, and passport information are consistent.
Outstanding payments: Check whether a deposit or another payment is required before CAS assignment.
Unclear financial information: Provide the evidence requested by the university and explain any issues honestly.
Missed communication: Monitor your email and student portal for updates or additional requests.
Last-minute applications: Start early enough to complete the university and visa processes without unnecessary pressure.
