Ok quick question actually I have read this here but cannot remember the answer. Few hours to half day overstay no 500 Bhat fine correct? and any funny stamp on passport while taking a flight out? overstay/understay etc?
TLDR : Answer Summary
In Thailand, if you overstay your visa for a few hours to half a day, there is no fine. However, there will be an overstay stamp placed in your passport when you exit the country.
