Understanding Your CAS (Confirmation of Acceptance for Studies)

A CAS number is one of the most important pieces of paper in your entire journey to the UK — and one of the least understood by first-time applicants. This page explains what it is, when you get one, and how our admissions support helps make sure yours is issued correctly and on time. It is not immigration advice, and we’ll say clearly where our role ends and where you need an official or regulated source instead.

What a CAS Actually Is

A CAS (Confirmation of Acceptance for Studies) is a unique reference number issued by your UK university, confirming that they’ve accepted you onto a specific course and that you meet the “genuine student” requirement — it is not a physical document, but the number and the details behind it are required to complete a UK Student visa application. Without a valid CAS, a Student visa application cannot proceed.

When a CAS Is Issued

Universities issue a CAS only after you have:

• Accepted your offer unconditionally — meaning every academic and English-language condition has been met and verified.
• Paid any required tuition fee deposit, where the university requires one.
• Confirmed your course, start date, and level of study with the university.

This is exactly why the sequence matters: Offer Acceptance Support → Document Review → CAS. Rushing or skipping a step earlier in the process is one of the most common reasons a CAS gets delayed.

What Information Your CAS Contains — and Why Accuracy Matters

Your CAS records specific details — your course, level, dates, tuition fee, and the qualifications you used in your application — and these details are checked directly against your visa application. A mismatch between your CAS details and your visa application is a genuine, well-documented cause of visa complications. This is precisely why document accuracy earlier in the process (Document Review) isn’t a formality — it’s the reason your CAS, when issued, is correct the first time.

CAS Validity

A CAS has a defined validity period and is generally tied to a specific visa application window — it isn’t indefinite, and using it against the wrong intake or after it expires causes real problems. We’ll make sure you understand your specific CAS’s timeline, not a generic one.

What We Help With

• Making sure every condition attached to your offer is genuinely met before your university is asked to issue a CAS, so there’s no back-and-forth at the last stage.
• Explaining what your specific CAS says, in plain terms, once it’s issued.
• Checking that your CAS details are internally consistent with your application and documents — catching a mismatch before it becomes a visa-application problem, not after.

What We Do Not Do

We do not provide immigration or visa advice. Advising on visa applications is a regulated activity in the UK under OISC (the Office of the Immigration Services Commissioner), and only OISC-registered advisers (or equivalent qualified professionals) are permitted to do this. Our role is admissions coordination — making sure your CAS is issued correctly and on time from the university’s side. For anything specific to your visa application itself, we will always direct you to the official UK government guidance (gov.uk) or a qualified, regulated immigration adviser — never guess or improvise on your behalf.
