Visa 30+ days for American I'll be traveling to Thailand in 2 weeks and did not apply for a visa. I'm American and I plan to be there for about 45 days. I only have a one way flight into Krabi thus far -- this was a bit last minute. From my research, I've gathered that I have 30 days of visa exemption and then I would need to reapply to stay for longer. So, does this mean that upon arrival I need to provide a bus/train ticket as evidence that I'll be leaving the country within 30 days? When I leave and come back, do I need to show proof when I return that I will be leaving the country again within another 30 days? Do the modes of transportation out of the country matter here? 

Any advice would be much appreciated. Sort of concerned because I don't have that much time ...
