When the school submits the work permit to the labour department on the end of the employment of an alien (teacher), does it automatically cancels the extension (with multiple entry) of the alien staying in the Kingdom of Thailand?
TLDR : Answer Summary
When an employer submits a work permit to the labor department after an employee's contract ends, it does not automatically cancel the employee's visa extension. The individual must visit the immigration office to formally cancel their extension if necessary. Confusion often arises regarding the difference between visa validity and extensions of stay. The individual is responsible for managing their visa status, especially to avoid overstaying penalties.
