The Confirmation of Acceptance for Studies (CAS) is a reference number issued by Imperial that an applicant needs to submit a Student visa application.
Once an applicant has met the conditions of their offer, the CAS will be issued by the relevant Admissions team.
Current students needing to extend their visa, or students returning from an interruption of studies, will need to request a new CAS number from the International Student Support team.
Please refer to the sections below that provide more detail.
