What steps should I follow for a border run in Thailand on a medical visa?

went to nong khai to do border run. have US passport. was on medical visa (correct me if thatz wrong name, please, 30 days length) i use a young lady (this is how i want to do it, has worked every time and i feel comfortable with that, so don't need to know itz easy. i find not much easy in Thailand) crossed border, drove back, got 30 visa day tourist visa exempt and all good until feb 27. i went a day early because being on last day makes me incredibly nervous. this is just informational. please close commenting if you feel necessary. thanks again thai visa advice. i read every day but, like admins say, if in question, go to immigration office in your area to find out the rules and laws they will want you to do. is only way to be sure, or should say, best way to be sure because always can want something else. keep calm, don't yell or get excited, this is thailand and is their country. we are here at their pleasure. shalom cheers aloha, jb
