stop talking nonsense. I get 5.5% in Australia interest. Look it up, ING savings maximiser, Now tell me how much interest Thai banks pay for a standard account? Then you will have the answer. And as you should know we in Australia do not pay anything for ATM cards and I don't pay for cash deposits either. So how is it that we have zero fees and Thailand has many fees? Just asking for a friend.
Sydney Thai Consulate did not ask for my flight tickets. My arrival and departure is 4 months apart with nothing inbetween. Where it asks for arrival date I put my flight number and date, then I added 60 days and on the departure I put "bus" and date. It was approved no problem. When I arrived at Suvarnabhumi I was stamped in for 60 days and no questions were asked.
Think of it practically. A tourist arrives on a 60 day visa. The whole idea of the long visa is to see the country and stay in many different hotels. Nothing ever happens if you just leave and go home after the 60 days, no one cares. It only comes to light when you need to go to immigration say for an extension, then you might need to pay the fine if your last place didn't register you. The way around the fine is to do a border run or do as I do and go to a neighbouring country and get a new tourist visa. So in general if you arrive on a 30 day visa exempt or a 60 day tourist visa and you leave the country when that visa expires the TM30 doesn't affect you, no one questions that at the airport. I have been doing this way for 3 decades and I have never had a problem but then again I never go to immigration for an extension of stay either.
I was asked for my accommodation booking in May last year, first time in 32 years. I have never been asked for the return flight. The Immigration Officer appeared to be new at his job and was nervous and took a long time to process me. I had a 60 day tourist visa. On my second visit back last year, nothing was asked, stamped in a thumbs up and off I went.
The problem is more the airline than Thai Immigration. I always get the 60 day tourist visa so it wouldn't worry me in this case. But I have done a Vietnam trip before Thailand and the airlines at all airports asked for forward travel. You see as
said the law is clear and you can get pulled up on it in Thailand. The reality is though that over 33 years of going to Thailand Thai Immigration has never asked me to show onward flights. Take the risk if you want to but a tourist visa is cheap and the best way to go for your case.
