Ayy guys, so today is the last day for me in Thailand, i'll be leaving tomorrow. The thing is my stay here expires today, so I'll have one day overstay. I came 2nd of Dec and thought OK add 30 and i can stay until the 1st of Jan, but i forgot to add the same day. I was wondering what's the process here? Do i strictly go to airport boarder pass control and tell them that i overstayed one day and they will charge 500 or how does it go?
TLDR : Answer Summary
If you have a one-day overstay in Thailand, proceed to the airport for passport control. They will recognize the overstay and direct you to a special desk where you will receive an overstay stamp in your passport. Typically, if the overstay is less than 24 hours, the fine may be waived at international airports. Ensure you have your flight ticket ready as evidence of your departure, and don't worry too much about potential issues from immigration, as there is no need for excessive concern.
