IRL you CAN'T go out of Thailand. There are a lot of people stopped by Immigration in both of Bkk airports by a reason - you are not a real student. Just for fun, to show a power. Nothing helps. IDC and deportation. I don't recommend you to go out of Thailand. You have a big Chance to be refused on arrival
Steve Greir Yes. Aranyaprathet Boarding Pass can do it surely. Trat 1 border can do, 1 border can't do (Pong Nam Ron can't do surely). Really for topicstarter will be better, if he will make a reentry permit by his immigration before. 1 photo and 1000 thb for single, 3900thb for multi reentry. This price is equal everywhere, it's a government tax.
Multiple entry is better if he wants to visit another countries as often as he wants, this type of Reentry is valid till the end of his visa extension
If your visa has 1 year extension (not multi), you have to make a Reentry. Or in your immigration office on in airport or on the land border (but this service somewhere isn't available). Enjoy your travel!
