When is the best season in Koh Samui?

Do I actually have to study?
Yes. The Ministry of Education inspects language schools several times a year, attendance below roughly 80% causes the visa letter to be withdrawn, and Immigration has interviewed ED applicants in Thai since 2023. Treat the course as a real commitment, not a visa product.
How to choose a school?
Check that the school holds current Ministry of Education accreditation, keep class sizes to about eight students, insist on native Thai teachers and regular progress testing, and expect THB 25,000–45,000 per year. Prices far below that are a warning sign of a shell school selling visa letters.
Can I work on an ED visa?
No. All employment, paid or unpaid, is prohibited without a work permit, and enforcement includes fines, deportation and a re-entry ban. To work legally you must switch to a Non-B with an employer-sponsored work permit, or hold an LTR or SMART visa that includes work rights.
