If you're a Bangladeshi student planning to study in the UK, the Confirmation of Acceptance for Studies (CAS) is the most critical document standing between you and your student visa. This guide breaks down everything you need to know for 2026 intakes—updated with the latest rules, timelines, and practical tips for Bangladeshi applicants.
What is a CAS Letter?
A CAS (Confirmation of Acceptance for Studies) is an electronic document issued by a licensed UK university. It contains:
A unique 14-digit reference number
Your course details (title, level, start/end dates)
Tuition fees and any scholarships
Accommodation costs (if applicable)
Your personal information
The UK Visas and Immigration (UKVI) uses this to verify you're a genuine student—not someone using education as a backdoor to immigration. Without a CAS, you cannot apply for a UK student visa.
Why CAS Matters More Than Ever in 2026
Study visas granted to Bangladeshis (year ending June 2025): 11,088
Refusal rate (2025): 18%
Approval rate (top nationalities, Mar 2025): ~80%
Q1 2026 visa issuances: Rose 27% to over 48,000 overall
Bangladeshi applications: Dropped 30% in 2025 due to stricter scrutiny
Growth since 2019: 300% increase in applications
Key takeaway: Stricter rules mean meticulous preparation is non-negotiable. Delays in securing your CAS can cost you your intake slot or force rushed (and expensive) visa processing.
Eligibility Criteria for CAS (2026)
You must meet requirements set by both the university and UKVI:
Unconditional Offer
Meet all academic conditions (minimum GPA in HSC or Bachelor's from a recognized Bangladeshi institution).
Tuition Fee Deposit

Sufficient funds for:
Tuition fees (minus deposit)
Living costs: £1,334/month (London) or £1,023/month (elsewhere) for up to 9 months
