CAS Letter for UK Study Visa: Timeline, Documents and Common Delays

CAS Letter for UK Study Visa: Timeline, Documents and Common Delays

If you’re reading this, you’ve probably received an unconditional offer from a UK university and already paid your deposit. The next step to secure a student visa is the CAS letter. You might find it a bit challenging to successfully pass this phase. If the online information is confusing and scattered, and you're struggling to find the real path to deal with the CAS letter, this guide is for you.

Let’s cut to the chase and cover everything you need. We’ll discuss what causes CAS letter UK delays, the CAS number, and required documents.

What Is a CAS Letter?

A CAS letter, short for Confirmation of Acceptance for Studies, is an electronic reference, not a physical letter you’ll receive in the post, issued by your university. The record itself, however, lives on the Home Office’s Sponsor Management System.

You’ll need the unique 14-digit CAS number it contains to apply for your student visa. It's easy to confuse a CAS with an offer letter, but they serve different purposes. An offer letter confirms that a university has offered you a place on a course, whereas a CAS confirms your acceptance for sponsorship purposes when applying for a UK Student visa. Even if you have received a fully unconditional offer, you may still need to wait for your CAS, as the two documents are not necessarily issued at the same time.

The CAS is also more than just an administrative document. Under the UK's points-based Student visa system, a valid CAS contributes 50 of the 70 points required to qualify for a visa. The remaining 20 points are awarded for meeting the financial requirements. This means that your CAS and proof of sufficient funds are two essential elements of your visa application.

Just keep in mind that having a CAS doesn't guarantee your visa will be approved. It confirms your place and sponsorship, but the Home Office still assesses the rest of your application independently.

What Information Is on a CAS?

CAS letter isn't limited to a reference number; it also includes your personal details, CAS number, and the university sponsorship information and license number. In most cases, your course details, fees, and deposits you’ve paid are also documented in the CAS letter. Accommodation details are also included if you’ve arranged it through the university. English test scores and financial evidence you’ve submitted are also mentioned in the CAS letter.

This may come as a surprise, but your CAS won't list every qualification you hold, only the ones your offer was actually based on. It also won't show your grades, with one exception: your English language test grade, which does appear.

When Is a CAS Issued?

CAS timelines can be different from one university to another, so don’t be surprised if your friends receive theirs before you do. For instance, the University of Glasgow generally begins issuing CAS letters around four months before the course starts. However, students who accept their offers later may be able to receive theirs sooner. Kingston University, on the other hand, allows students to access its CAS application portal up to six months before their course begins.

Before your university can issue your CAS, there are a few things to sort out:

• Your offer needs to be unconditional, meaning all academic and English language requirements have been met.
• The required deposit should be paid, unless you're providing evidence of scholarship funding or another approved form of sponsorship.
• Any documents requested by the university must be submitted.
• You may also need to confirm that you're not holding multiple unconditional offers at the same time, as some universities have specific rules about this.

You might also come across a platform called CAS Shield during the process. It's used by universities such as Exeter and Kingston to manage CAS applications and verify student information. Although it may look like an official immigration system, CAS Shield is a university-facing tool, not a UK government service. So, if your university asks you to complete something through this platform, it's simply part of its CAS procedure.

Once you receive your CAS number, you can move on to your UK Student visa application. According to the government’s guidance, you can apply up to six months before your course starts if you're applying from outside the UK, or up to three months in advance if you're applying from within the UK. If you're switching from an existing visa, your new course must also start within 28 days of your current visa expiring.

CAS Letter Processing Time

There isn't one fixed waiting time for a CAS. It depends on your university, whether you've completed all the required steps, and how busy the admissions team is. This is a rough idea of what to expect at different universities:

• Exeter: Usually around 3 working days once all CAS Shield requirements have been completed.
• University of Glasgow: Your CAS number is generally emailed within 3 working days after your draft has been approved.
• Kingston University: Typically, 3 to 5 working days once your application status changes to Ready for CAS.
• Royal College of Art (RCA): The process can take around 2 to 3 weeks on average.
• Other UK universities: Processing times vary, but a wait of 5 to 20 working days is a reasonable general estimate. Many universities aim to complete the process in around 10 working days.

Keep in mind that these are estimates, not guaranteed deadlines. Even if your university processes CAS applications quickly, payment delays can hold things up. If you've paid close to your visa appointment, the payment might not appear on your CAS in time.

The time of year can also affect processing times. Between June and August, universities often handle a much higher volume of international student applications, so the process may take longer than usual.

Submit any outstanding documents, and make sure your deposit has cleared well before you plan to apply for your visa. That way, you're less likely to face an unexpected delay.

Common Reasons CAS Letters Get Delayed

CAS letter delays can happen for several reasons, and not all of them are within your control. Some of the most common issues include:

• Details that don't match: Even small differences in your name, dates, or course information across documents can hold things up.
• Financial documents under review: Bank statements may need further checks, especially if they're outdated, don't meet the requirements, or show large deposits without a clear explanation.
• Something's missing: Your application might be waiting on an English test result, academic transcript, passport copy, or TB test report.
• Still on a conditional offer? If you've not met all the conditions of your offer, the university may not be ready to issue your CAS.
• The summer rush: June to August is a particularly busy period for admissions teams. More applications often mean longer waiting times.
• Payment hasn't cleared yet: Paying your deposit doesn't always mean the university has received and processed it. Bank transfers and payment verification can add extra days.
• University admin delays: Sometimes, the problem is simply an internal backlog. These delays aren't limited to less-established universities, either.

A delay doesn't automatically mean there's a problem with your application. It could be a missing document, a payment issue, or simply a university team struggling to keep up with demand.

What If There's an Error on Your CAS?

A CAS with incorrect information is a different problem from a delayed one. This means the CAS has been issued, but something went wrong. The most common reasons for this include:

• Name or passport mismatch: Your CAS has to match your passport exactly. If the error is caught before issue, it's fixed directly in the application portal; if the CAS has already been issued, you'll need to contact the university's CAS team directly with a copy of your passport.
• Wrong course or a change of plans: If you want to change course or university before your CAS is issued, contact admissions first since no CAS will be issued until that's resolved. After issuing CAS, transfers are generally not permitted and require a formal request process.
• Missing scholarship or funding: It's important to know that this information doesn't automatically appear on your CAS. You'll usually need to confirm or add this yourself through the university's finance process.
• Previous UK study flagged: Universities check this against UKVI's academic progression rules. Generally, a second Student visa requires a higher level of qualification than your previous UK one.

Minor errors are typically fixed with what universities call a sponsor note. Multiple significant errors, on the other hand, can require a full CAS reissue, which resets your processing clock.

Common Mistakes to Avoid

Check your CAS carefully before applying, ensuring your name, passport details, course information, and other details match your documents exactly. Don’t make extra payments without confirming with your university whether they’ll update your CAS accordingly.

Remember, your offer letter cannot replace your CAS for a UK student visa application. Also, avoid booking non-refundable flights or accommodation until your visa is approved to prevent unnecessary financial losses.

CAS Letter Validity and What Happens If It Expires

A CAS is often valid for six months from its issue date. If your visa application is refused, you’ll need a new CAS. The right first step is contacting your university’s admissions team, since they’ll advise on whether a new one can be issued rather than you needing to restart the whole process from scratch.

Another important thing to consider is that your CAS dates might not match your offer letter exactly, and that’s often intentional. Exeter, for instance, sets CAS start dates up to nine days before the official offer date for September intakes, to account for arrivals weekend and Welcome Week. PhD students may see a CAS end date running six months past their offer end date, built in to cover the viva. Neither is an error.

Frequently Asked Questions

1. What should I do if the name on my CAS differs from the name on my passport?

Any discrepancy between your CAS and passport details should be resolved before submitting your visa application. If your CAS has not yet been issued, you can usually update your details through your university's application portal. If it has already been issued, contact the university's CAS team and provide a copy of your passport so they can arrange the necessary correction.

2. Is it possible to apply for a UK student visa without a CAS letter?

No. You must have a valid Confirmation of Acceptance for Studies (CAS) number to apply for a UK Student visa. An offer letter from your university cannot be used as a substitute for a CAS.

3. Why is the course start date on my CAS different from the date on my offer letter?

A difference between these dates does not necessarily indicate a mistake. Some universities include additional time in the CAS to accommodate arrival arrangements and orientation activities, particularly for September intakes. For PhD students, the CAS end date may also be extended to allow sufficient time for the viva examination.

4. What if I want to change my course or university after my CAS has been issued?

Making changes after your CAS has been issued can be more complicated than doing so beforehand. Universities generally find it easier to process such requests before issuing the CAS. Once it has been issued, you may need to submit a formal request, and approval is not guaranteed.

5. Will my CAS include my academic grades and qualifications?

In most cases, your CAS lists the qualifications used to assess your eligibility for the course rather than providing a detailed record of your academic grades. However, information about your English language test result may also be included.

6. What happens to my CAS if my UK student visa application is refused?

If your visa application is rejected, you may need a new CAS before applying again. Your first step should be to contact your university's admissions team, which can explain whether another CAS can be issued and advise you on the appropriate next steps.

7. Can I receive CAS letters from multiple UK universities simultaneously?

You may receive CAS numbers from different universities. However, once you use one CAS to submit a visa application, the other CAS records may become invalid for that purpose. A Combined CAS is a separate arrangement that may be available to students studying multiple courses concurrently at the same university, subject to the relevant requirements.

8. Why is my scholarship or sponsorship funding missing from my CAS?

Scholarships and sponsorships that have not yet been confirmed may not automatically appear on your CAS. If you have received funding or expect an award to be included, contact your university's finance team to confirm the details and ask whether the funding information can be updated.

9. Can I receive a deposit refund if my visa application is refused?

A refund may be possible, depending on your university's refund policy and the circumstances of your refusal. You will generally need to submit a copy of your visa refusal letter. Keep in mind that some universities may deduct an administrative charge, and refunds are not always guaranteed.

10. Does every student have to attend a pre-CAS interview?

No. Pre-CAS interviews are not compulsory for all applicants. Whether you need to attend one depends on your university's procedures and, in some cases, your country of origin or individual circumstances. Your university will inform you if an interview is required as part of its CAS assessment process.

11. When should I expect my CAS, and when can I apply for my visa?

After accepting your offer and paying your deposit, you can usually request your CAS around 4 to 6 months before your course starts. Your university may ask you to confirm your details or attend a pre-CAS interview before issuing it.

Once your CAS is issued, you can use it to apply for your Student visa. If you're applying from outside the UK, you can submit your visa application up to 6 months before your course starts. If you're applying from inside the UK, you can usually apply up to 3 months in advance. Just remember that you'll need your CAS number before you can submit your visa application.
