How Long Does It Take to Get a CAS Letter in the UK?

For international students planning to study in the United Kingdom, receiving the Confirmation of Acceptance for Studies (CAS) letter is one of the most important steps in securing a UK student visa. The CAS letter serves as official confirmation from a UK university that you have been accepted onto a course and that the institution is sponsoring your visa application.

But how long does it take to get a CAS letter once you’ve accepted an offer? What factors affect the CAS issuance timeline? And how can students speed up the process? In this blog, we’ll break it all down.

What is a CAS Letter?

A CAS letter is an electronic document issued by a UK Visas and Immigration (UKVI)-licensed university that confirms:

• You have an unconditional offer of admission.

• Your course details and duration.

• Tuition fees and payment status.

• Your unique CAS number (used in your visa application).

It is not a physical letter but a digital reference number that must be submitted when applying for your Student visa (formerly Tier 4 visa).

When Is a CAS Letter Issued?

The CAS letter is issued after:

1. You accept the unconditional offer from the university.

2. You pay the required deposit toward your tuition fees (typically between £2,000–£5,000).

3. You submit necessary documents such as:

   • Academic transcripts

   • Passport

   • English proficiency test results (like IELTS or PTE)

   • Financial evidence (to meet visa requirements)

4. You successfully complete a credibility interview (if required).

5. You pass the university’s internal pre-CAS checks.

Only after all these steps are verified will the university process and issue your CAS.

How Long Does It Take to Get a CAS Letter?

Typically, the CAS letter is issued within 7 to 20 working days after all required conditions are met. However, the time frame may vary based on several factors:

1. University Processing Time

Each university has its own timeline. For example:

• University of Birmingham: 10–15 working days.

• Coventry University: Usually 7–10 working days.

• Manchester Metropolitan University: Around 10 days after completing pre-CAS steps.

• Ravensbourne University London: Around 7–14 working days after fee payment and document submission.

2. Peak Admission Periods

During busy intake periods (especially June–August for the September intake), CAS processing may take longer due to high application volumes.

3. Incomplete or Incorrect Documents

If your financial documents or academic transcripts are incomplete or contain errors, the university may pause CAS issuance until you resubmit correctly.

4. Verification or Additional Checks

Some universities conduct additional credibility interviews, especially for applicants from high-risk countries. This can delay CAS issuance.

CAS Timeline: Step-by-Step Example

Let’s look at a sample timeline for a September intake student:

Tips to Receive Your CAS Letter Quickly

To ensure a smooth and timely CAS process, follow these tips:

✅ Accept Your Offer Promptly

Once you receive your unconditional offer, respond without delay.

✅ Submit All Documents Early

Prepare and submit academic certificates, passport, English test results, and proof of finances early in the process.

✅ Pay Tuition Deposit on Time

Your CAS will not be processed until you’ve paid the minimum deposit required by the university.

✅ Double-Check Financial Documents

Ensure your bank statements or loan letters meet UKVI financial guidelines:

• Must be in your name or a parent's name.

• Must show funds maintained for 28 consecutive days.

• Must be recent (dated within 31 days of visa application).

✅ Attend University Pre-CAS Interview (if required)

Prepare well for any credibility interview to avoid delays or rejections.

What is a CAS Deadline?

Most UK universities have a CAS deadline, usually 6–8 weeks before the course start date, to allow sufficient time for visa application and travel.

Failing to meet this deadline may result in:

• Delay to your visa process.

• Deferral to the next intake.

• In some cases, cancellation of your admission.

Pro Tip: Always confirm the CAS deadline for your chosen university.

Can the CAS Letter Be Reissued?

Yes, but only under certain conditions. A CAS may be reissued if:

• Your personal details were incorrect (e.g., spelling of name or passport number).

• Your course start date was deferred.

• You need to switch universities or intake.

However, universities usually limit the number of times they will reissue a CAS. Misuse or repeated changes can be flagged by UKVI.

CAS Letter vs. Visa Application

Once you receive your CAS letter, you can use it to apply for a UK Student visa, typically no earlier than 6 months before your course start date.

Key items needed for your visa application:

• CAS number and university sponsor details.

• Valid passport.

• Financial documents.

• ATAS certificate (if applicable).

• Tuberculosis test (for certain countries).

The CAS letter is your gateway to securing a UK Student visa, and understanding the timelines and process can help you plan better. On average, it takes about 7 to 20 working days after meeting all pre-CAS requirements, but delays can occur due to incomplete documents, peak processing seasons, or university-specific checks.

To avoid unnecessary delays:

• Be prompt in submitting documents.

• Prepare financials as per UKVI standards.

• Communicate clearly with your university or agent.

With proactive planning, you’ll receive your CAS well in time to start your academic journey in the UK.
