What should I do if I am on an overstay in Thailand?

If you are on an overstay in Thailand, your best options are to either exit the country and pay the overstay fine at the airport or visit your local immigration office to explain your situation and pay the fine there. Some expats consider applying for an extension at the immigration office, but this is often refused, likely granting you a short grace period to leave the country. It's important to handle the situation promptly to avoid penalties or possible detention.
