people with US tourist visa can stay 6 Mo's at a time. How much does Thailand give farangs, at most 90 days. Unless you know the visa requirements of every country you shouldn't make such stupid comments
your not a US citizen so what the hell you know. The US gives a 10 year multi entry visa and you can stay for 6 mos. The US is tough but much more generous than Thailand. And it's a pain in the ass to get a retirement visa in Thailand. If you know not then speak not!
Super hard for a Thai to get a tourist visa to the US. One thing they want to see is that they have been to other countries and returned to Thailand. Get her a Schengin visa and go on a vacation to Europe. It's easier to get than US visa. Also does she own property or have a good job? It helps. I just resently wrote an invitation letter for a friend and he was denied because he had never been outside of Thailand.
