Are there any issues or penalties for leaving Thailand on an education visa?

A person on a Thai education visa (ED visa) can generally leave the country. However, if they leave while the visa is still valid, it is important to check any specific rules that may apply regarding re-entry. Typically, there should be no penalties for leaving or returning, even if the duration outside of Thailand is less than three months. Nonetheless, it is recommended to confirm with the immigration authorities or the institution that issued the visa to avoid any potential issues during re-entry.
