- Confirm visa-and-school sequencing — student visas are issued through the school, but enrolment fees often run concurrently.
- Ask about CAS and IB Diploma performance — schools differ widely in average IB scores and university destinations.
- Visit at school start time — Bangkok traffic can double a 20-minute trip in monsoon season.
- Negotiate transport and uniform inclusions if your employer is paying tuition directly.
