Do you need a medical check for a NON-B visa for employment in Thailand?

A medical check is generally not required for obtaining a NON-B visa for employment, especially for positions that are not teaching. However, requirements may vary based on the employer's status; if the work permit is processed through certain channels (like MOL or One-Stop Service Centers not classified under BOI/IEAT), a medical certificate might be needed upon work permit renewal. Many clinics offer medical certificates for affordable prices, typically around 50 to 100 THB.
