CAS stands for Confirmation of Acceptance for Studies.
A CAS is a virtual document, that confirms that your institition is willing to act as your educational sponsor.
You must have an unused CAS for each Tier 4 visa application you make.
When you put your CAS number on your Tier 4 visa application form, this allows a UKVI caseworker to access your information electronically.
Your CAS will provide the UKVI caseworker with your personal details, details about your proposed course of study and any course related fees.
- Are an International Student
- Do not hold an EU, EEA or Swiss passport,
- Are coming to the UK to study for a course which is longer than 6 months
You will need a to make a Tier 4 visa application, if you do not already hold a visa for the UK that confers the Right to Study.
For information on how to request a CAS please see the relevant sections below for who is responsible for assigning your CAS for new students, continuing students and following a visa refusal.
Your Admissions Team will issue your CAS if:
- You are starting a new course at Warwick, after you have accepted an unconditional offer and within 3-4 months of your course start date, including if you are a visiting research student, i.e., you are currently enrolled in your home institution on a research course such as a PhD,
- You are re-starting a course.
- You are an incoming student for a period of
- Study Abroad
- Visiting Student
- Research placement
- Exchange at Warwick for longer than 6 months
- i.e., you are currently enrolled in your home institution on an undergraduate or postgraduate taught course such as a Master's degree.
- You are starting a new course at Warwick and require a 2nd CAS because you received a visa refusal before your 'latest start date'
- You will need to complete a refusal notification form which forms part of the new CAS request.
- You are taking the 10-week or 6-week Pre-sessional English language course.
Student Immigration & Compliance Team will issue your CAS if:
- You are a enrolled current student who needs to make a new visa application because:
- You have been granted a period of Academic Extension
- You are transferring to a longer course, including if you are adding a Study Abroad or Intercalated (Work Placement) Year
- You are downgrading to a lower level course, are resitting or repeating modules, or are switching to Tier 4 from a different visa category
- You started your PhD course at a partner University outside of the UK, for example, Monash University, and now require a Tier 4 visa for your period of study in the UK
- You are joining the Year-round Pre-sessional course, but not the 10-week or 6-week Pre-sessional course (i.e., Phase 4 & 5).
- You are returning to studies after a break from your course, for example, Temporary Withdrawal (TWD) or Resit Without Residence (RWR).
- You have gone through an 'Internal Upgrade' process from a Master's to a PhD course, i.e., you are not required to apply for your PhD separately, and will need a CAS for a new visa to complete the PhD course.
- You wish to apply for the Doctorate Extension Scheme (DES).
The 'Latest Start Date' on a CAS indicates the last day the university will accept your enrolment or re-enrolment onto the course.
This means you must have completed:
- The Online Enrolment
- Attended the In-persion Right to Study Check
This is also the last day you are able to enter the UK if you are travelling from overseas.
You must make every effort to arrive at the University on or before the 'Official Course Start Date' as indicated on your offer letter or your CAS.
If you arrive in the UK or complete enrolment after the 'Latest Start Date', you will not be permitted to join the course.
In very specific circumstances, exceptions to this apply.
You must talk to the team that assigned your CAS if you require further information or require urgent assistance.
It depends on whether you will make a visa application within the UK or outside of the UK.
