This question already has an answer here:
I bought a ticket to Thailand I arrive in Bangkok September 2nd, and leave October second. I essentially fly out on my 31st day in the country. I also have bought a one way ticket to Laos near the end of my trip to spend a few days there then was considering just crossing back over the border by bus.
I am not a little concerned that I may have an issue without having a visa (although I am going to leave the country for a day or two or more). I have just read so many different views on this. I tried to reach the consult, which seems to be quite challenging. I also live about 7 hours away from the nearest one and I am not in a window now to apply by mail. Any advice?
