Three days ago I went to Savannakhet to get a new tourist visa to enter Thailand. I already had two previous double entry tourist visas in my passport from over the last year. I hold a New Zealand passport, which usually is a prefered passport with many countries. I was told that they will only give me a single entry tourist visa from now on (meaning this time and next time, and so on) unless I bring proof of adequate funds from outside of Thailand for living off of. I got a single entry tourist visa, which is ok for me this time as I will take a holiday at the end of that ones validity anyway, so it isn't an immediate problem.
A Russian in front of me in the line also had two previous double entry tourist visas and said he had the same experience.
It seems there are some changes, temporary or otherwise, going on. I hope it is only temporary because going to Savannkhet every three months instead of every six months would be not only in general more expensive and time consuming, but really take away a lot of the fun of seeing other places in the region when doing visa runs.
