I'm not sure how to ask my own question. If not, you can delete this message. I then try find out how to do it the right way Question:border bounce Nong Khai: you stamp out Thailand. Can you get into Thailand immediately? Or do you buy a Laos visa, stamp in and out then come back Thailand?
TLDR : Answer Summary
To perform a border bounce from Thailand to Laos, one must stamp out of Thailand, purchase a visa on arrival for Laos, stamp in and out of Laos, and then re-enter Thailand by stamping back in. There is no mandatory duration for staying out of Thailand; many people simply stamp in and out quickly. An e-visa for Laos may be a convenient option to avoid long lines.
