If you’re planning to study in the UK, you’ve probably come across the term CAS letter more than once. But what is CAS exactly? Why is it so important? And what does a sample CAS letter even look like?
Don’t worry, we’ll break it all down for you!
What is CAS?
CAS stands for Confirmation of Acceptance for Studies. CAS letter is a unique document issued by your chosen UK university once you’ve accepted an offer and met all the conditions. In short, it’s your ticket to applying for a UK student visa.
Without a CAS letter, you can’t apply for a Student visa to study in the UK. It’s as crucial as your passport and offer letter—seriously.
What’s Inside a CAS Letter UK?
Think of your CAS letter as a digital document that contains all the key details UK Visas and Immigration (UKVI) needs to approve your Student visa. It includes:
- Your CAS number (a unique 14-digit reference code)
- Your personal details (name, date of birth, etc.)
- Details about your course: name, level, start and end dates
- Tuition fees (and any payments you’ve already made)
- Confirmation of your English language ability
- Your university’s sponsor licence number
Even though it’s called a “letter”, you won’t receive a paper copy. Instead, it’ll be emailed to you by your university, usually as a PDF or in the body of an email.
When Do You Receive Your CAS Letter?
Once you’ve:
- Accepted your unconditional offer
- Paid any required tuition deposits
- Passed any required pre-CAS checks (like financial documents or interviews)
Remember, your university will issue your CAS letter UK.
This typically happens within a few weeks before your course starts, depending on your university’s timeline. So, it’s a good idea to keep checking your emails and submit your required documents early.
What is a CAS Number?
Your CAS number is the unique 14-digit reference that links your Student visa application to your university. It’s how the UK Home Office identifies your acceptance by a licensed sponsor. You’ll need to enter this number when filling out your visa application form.
Think of it like a secure reference code that confirms your student status in the UK.

Common Questions About the CAS Letter UK
1. Can I make changes to my CAS once it’s issued?
Only in certain cases. If there’s a mistake or your details change, inform your university immediately. A new CAS might be needed.
2. What if I apply late?
Many universities have a CAS issuance deadline—don’t wait till the last minute.
3. Can I use one CAS letter for multiple visa applications?
No. A CAS number is valid for one application only. If your visa is refused, you’ll need a new CAS to reapply.
