I got told that you are require to show a ticket proving that you are leaving thailand within 45 days if you enter the country on with exempt but do you also have to provide a ticket that proves you are flying out if you have a visa (in my case, a single entry tourist visa)? some folks told me that there's no need while other told me that's mandatory. What is your experience with it? My main concern it about spending money on a ticket which I won't use (because I have to leave the country within 60days while I'd do a visa extension and leave in 90days). Besides of those websites giving you "prenotations" for 15us$, do you have any other solution?
