CAS Issuance (Confirmation of Acceptance for Studies)
A step-by-step guide for international students to obtain their Confirmation of Acceptance for Studies (CAS) from a UK university. The CAS is a mandatory electronic record containing a unique 14-digit reference number required to apply for a UK Student visa. The process begins with holding an unconditional offer and paying the required tuition fee deposit. You then submit supporting documents (passport, academic transcripts, English language test results, deposit receipt) through the university portal. The university immigration compliance team reviews your eligibility under its UKVI sponsor licence and, once approved, assigns the CAS electronically. The CAS number is valid for 6 months and can only be used once. Universities typically issue CAS documents 3 to 6 months before the course start date. The entire process from deposit payment to CAS issuance typically takes 2 to 6 weeks.
Step-by-step guide
Accept Your Unconditional Offer
Before a university can issue a CAS, you must hold an unconditional offer. If your offer is conditional, you will need to provide evidence that you have met all academic conditions (such as final transcripts and degree certificates) and English language requirements (such as IELTS or TOEFL results) through the university applicant portal. The university will update your offer status to unconditional once all conditions are satisfied. Only after holding an unconditional offer can the CAS process begin.
Pay the Tuition Fee Deposit
Most UK universities require international students to pay a tuition fee deposit before they will issue a CAS. Deposit amounts vary by institution, typically ranging from 2,000 GBP to 8,000 GBP. The deposit is deducted from your total tuition fees. The amount paid can be recorded on your CAS, which reduces the financial evidence you need to show in your visa application. Check your university finance pages for the exact deposit amount and accepted payment methods.
Submit CAS Request and Supporting Documents
Complete the CAS request form provided by your university, usually available through the applicant or student portal. You will typically need to provide: a copy of your passport (the same passport you will use for your visa application); your academic transcripts and certificates; English language test results; and proof of deposit payment. Ensure all personal details match your passport exactly, as any discrepancies between your CAS and visa application documents can cause delays or refusal. Some universities may also require a credibility interview before issuing the CAS.
