Yes, you heard it right!

It is the most essential document that can be the turning point of your UK study visa application process. If you need complete information on the Confirmation of Acceptance for Studies (CAS) letter from the UK, read ahead. 

In this blog, we’ll discuss the importance of the CAS letter and guide you through the necessary steps to acquire it.


What is a CAS Letter UK?

The Confirmation of Acceptance Letter is a personalized letter from the educational institution you have applied to. It is one of the most important pieces of evidence needed to obtain a UK visa. It confirms that the university has accepted your application and that you are now eligible for a UK study visa.


Requirements for CAS 

To apply for your UK CAS letter, you need to fulfill certain requirements. For this, you’ll have to submit the following documents:

  • Original documents and credentials 
  • Mark sheets and other academic transcripts
  • Updated passport 
  • Financial evidence

UK institutions send CAS letters and numbers to international students who have accepted the offer and paid the deposit payment for the program. After the CAS acceptance letter is sent, the students can initiate the UK study visa application process.

Before the issuance of CAS, the university sends an offer letter. The next steps for each university in the UK can be different. However, when students accept the offer letter, the university tells UK Visas & Immigration (UKVI) regarding the student’s acceptance to the university. In addition, it also asks for the CAS number on the student’s behalf. UKVI gives the CAS number to the university, which then the university sends to the accepted student.


Steps to Apply for a CAS Letter UK

Here are the easy steps through which you can apply for a CAS letter UK:

1. Accept the Offer Letter and Pay Your Fees

The first step in applying for a CAS letter in the UK is to accept your offer letter. This letter can either be conditional or unconditional. To receive this, students must pay the acceptance fee, which can be around £6,000.

In addition, international students must provide evidence of their academic qualifications and English language ability (if required). These documents are essential to obtaining the offer letter.

Once you have submitted all these documents, paid your acceptance fee, and accepted an unconditional offer, you are good to go. 

2. Wait for Your CAS Issuance

After you have provided all the required information and documents, you’ll have to wait for your institution to issue your CAS. This may take some time, so you should apply well ahead of time than the expected start date of your study program in UK.

3. Receive CAS

After your CAS is provided to you, you will be notified electronically from your institution. Be sure to examine all the details of your CAS to make sure they are right.

4. Apply for the UK Study Visa

When you receive your CAS letter, you will be able to apply for your student visa (usually a Tier 4 visa for full-time students). To submit the study visa application, you’ll need to fill out the online application form, submit the application fee, and make an appointment for biometrics at the visa application center.

Besides, you will have to submit various other documents among which your CAS, passport, financial evidence, and any other necessary documents will be included.
