UK Student Visa Delays: Six-Month BCA Backlog Hits CAS and Extensions
A growing administrative backlog in the Home Office Basic Compliance Assessment is disrupting CAS issuance and visa extensions for international students. Universities face uncertainty while refusal rates continue to climb across key source markets.
BCA Review Backlog Creates Widespread Disruption
A six-month delay in the Home Office Basic Compliance Assessment process is affecting universities ability to issue new CAS numbers and support visa extensions.
Key Caveat
The BCA process reviews sponsor compliance and does not directly decide individual visa applications, yet the backlog indirectly restricts student mobility.
Administrative reviews lodged against refusals are excluded from BCA calculations, contributing to the extended processing times now reported at six months.
Rising Refusal Rates Compound the Issue
- Refusal rates for students from Pakistan have risen nearly six-fold to 41%
- Several other major source countries have seen refusal rates double or triple
- Credibility grounds remain the leading reason for refusals
These trends coincide with the BCA delays, leaving institutions and applicants in a prolonged state of uncertainty.
Impact on Students
Without a valid CAS, new applications and extensions cannot proceed, affecting course start dates and post-study plans.
What the Rules State
According to UKVI guidance, sponsors must maintain acceptable refusal rates to retain their licence. Ongoing administrative reviews are currently excluded from these calculations.
| Period | Immigration Officer Decisions | Social Worker Decisions |
|---|---|---|
| Jul 2025-Mar 2026 | 32% assessed as children | 68% assessed as children |
Does the BCA delay affect all universities equally?
The impact varies depending on each institutions current BCA status and volume of pending administrative reviews.
Can students still apply for visas during the backlog?
Applications may proceed only where a valid CAS has already been issued; new CAS numbers are currently restricted at affected sponsors.
Are refusal rates expected to change?
The Home Office has not published forward projections; current data shows significant increases across multiple markets.
