For many Pakistani students, the UK Student visa process starts to feel real only when you get your CAS letter. Studylead Consultants eases the burden on a family by making this step transparent and worry free. When you know what the CAS is, what is in it and what should be checked, you can avoid most of the last minute problems.
What is a CAS letter?
A Confirmation of Acceptance for Studies (CAS) is an electronic record created through the UK Home Office system by your university. It confirms you have been accepted on a course and gives you a CAS reference number you must enter in your visa application.
Many students call it a “letter,” but it is mainly the reference number and a CAS statement sent to you by email. You usually do not need a printed copy because the CAS is electronic.
Why the CAS is your “ticket”
You cannot apply for a UK Student visa without a CAS. The UK government lists the CAS as a required document for the Student visa application.
Your CAS also locks key details for the visa form, like your course, start date, and fee information. Universities describe it as a secure record shared with UK Visas and Immigration (UKVI).
When you get the CAS
Most universities issue the CAS after you meet all conditions of your offer. This commonly includes an unconditional offer, fee deposit (if required), and full document checks.
A practical warning: universities can face CAS limits and delays in busy periods, so do not leave it for the last week. A recent case reported that students faced uncertainty when a university exceeded its CAS allocation and had to work with the Home Office for more CAS numbers.
The 6-month rule you must know
The UK guidance says you must apply for your visa within 6 months of receiving your CAS. That means the CAS is not something you should “hold” for too long.
Once you receive it, most universities advise applying for the visa as soon as possible to reduce risk from processing delays.
What information is inside the CAS
A CAS usually includes details about you, your course, and your fees. Universities explain that it contains course and fee information and personal details, and you will need the reference number for the visa form.
It can also list the qualifications you used to get admission. Older UKVI guidance notes you must provide the originals of certificates or transcripts listed on your CAS.
One-table checklist: What to verify before you apply
What to check on the CAS | Why it matters | What to do if wrong |
Course title and level | Must match your offer and visa plan | Confirm with admissions before applying |
Course start date and end date | Impacts your visa timing and travel planning | Request correction if dates are incorrect |
Tuition fee and any fee paid | Affects the financial requirement you must show | Share payment proof and request an update |
Qualifications listed | You may need to submit exact documents listed | Prepare originals and translations if needed |
CAS reference number | Required in the visa application form | Enter carefully, exactly as provided |
Common reasons CAS gets delayed
Delays usually happen because something is incomplete or unclear. The easiest trick to evade delays is to clean your documents and payments as well as to be able to verify them..
- You still have offer conditions pending, so the offer is not unconditional yet
- The university is waiting for your passport copy or final transcript
- Your tuition deposit is not received or not matched to your student record
- Your course start date is close and the university is checking late arrival rules
- Peak season workload slows down CAS processing
Mistakes Pakistani students should avoid
Many visa problems come from small errors, not big ones. Treat the CAS like a final checklist, not a simple email to file away.
- Applying before you receive the CAS, or using an old CAS number
- Entering the CAS reference number incorrectly on the form
- Ignoring the 6-month window after CAS issuance
- Assuming the CAS “proves funds,” and under-preparing the bank evidence
- Not updating the university if your passport changes (some universities require CAS amendments in that case)
Final Thoughts
A CAS letter is not just a formality. It is your main gateway to the UK Student visa, and it must be accurate, timely, and matched to your documents.
