Thank you so much for all your help. You gave me a fantastic option. I will be with my family very soon. And I will make sure to be more diligent and visit this page more.
If you have the 500 baht to pay the fine, I wouldn't worry too much about it. Just ask where the overstay counter is before you stamp out , or wait in line and immediately inform the officer that you are on overstay and you would like to pay the fine. I know because I have a few, big ones small ones, but now I do try to avoid them , as officers may try to hassle you more than in the past. You should be golden though. Good luck. Sad to see you go :(
