What Is a CAS Letter?

CAS short for Confirmation of Acceptance for Studies. When you receive a Confirmation of Acceptance for Studies from a UK university, it is an official confirmation issued after you accept the offer and complete all the required steps.

The CAS letter is not a physical document that you receive by post. Instead, it is a unique reference number created by the university and shared with the student. This reference number confirms that:

  • You have been accepted to study at a university in the United Kingdom that is approved by the UK government
  • Your course details have been checked and approved
  • The university agrees to support your UK student visa application

This CAS reference number is very important because it connects your admission with your visa application.

Why Do UK Universities Issue a Confirmation of Acceptance for Studies Letter?

UK universities issue a Confirmation of Acceptance for Studies letter also known as a CAS letter to students who have been offered admission. This letter is required so that international students can apply for a UK student visa.

The main reason UK universities issue a CAS letter is to confirm that a student has secured a place to study in the UK. UK universities issue the CAS letter only after the student has accepted the offer and met all admission conditions. This process is required under the rules of UK Visas and Immigration (UKVI).

The CAS letter shows that:

  • The student is enrolled at a recognized UK institution
  • Course details, fees, and duration are approved
  • Immigration requirements are being followed

The CAS letter is very important for UK authorities because it provides them with all the details needed to assess a student visa application.

If a student does not have a CAS letter, the visa application will be rejected.

When Do Universities Issue the CAS Letter?

The CAS letter is usually issued after a student completes certain steps, such as:

  • Accepting the university’s offer
  • Paying the required tuition deposit
  • Submitting documents like passport, academic certificates, and test scores

Universities generally issue the CAS letter three to six weeks before the course start date. This allows students enough time to prepare and apply for their UK student visa.

Students should wait for the CAS letter before starting the visa application process to avoid any problems or delays.

How the CAS Letter Is Used for Visa Application

The CAS letter plays a very important role in the UK student visa application process. When applying for the visa, students must enter the CAS reference number exactly as it appears.

UK immigration authorities use the CAS letter to:

  • Verify student admission details
  • Check course and fee information
  • Ensure the student meets visa requirements

If any information in the visa application does not match the CAS details, the application may be delayed or even refused. This is why students must carefully check all details before submitting their visa application.

Taking guidance from a trusted UK Study visa consultant in Mumbai can help students avoid mistakes and complete the process correctly.
