FAQs
A Confirmation of Acceptance for Studies (CAS) is a unique reference
number
issued by a UK educational institution. It confirms that you have been offered
an unconditional place on a course and is required to apply for a Student visa.
You will receive your CAS after accepting your offer, meeting all
conditions
(academic and financial), and providing any required documents. Most
universities issue CAS letters around 3 months before your course start date.
Your CAS is valid for 6 months from the date it is issued, but you must use it to apply for your Student visa within 6 months of issue and no more than 6 months before your course starts.
Your CAS is valid for 6 months from the date it is issued, but you must use
it to apply for your Student visa within 6 months of issue and no more than
6 months before your course starts.
Only limited changes can be made. If there's a mistake (e.g. spelling of your
name, course title, or fee information), you must contact the university
immediately. Once a visa application is submitted using that CAS, it cannot
be changed.
If your visa is refused, you may request a new CAS, but you'll usually need
to provide a copy of the refusal notice and meet any additional requirements
set by the university. The institution reserves the right to issue a new CAS
based on the circumstances of the refusal.
