Hello! I'm headed to Hanoi to visit and get a SETV after my METV runs out. My plan to enter Thailand is actually by bus (possibly taxi) from Thakhek, Laos to Nakhon Phanom. I don't think I can prebook this bus trip so my question is, do I have to show the thai embassy in hanoi proof of entry or will my proof of departure be enough. Yes, I am allowed one more land entry.
thanks!
