First, ICE arrested me and is trying to rudely deport me because I forgot to apply for my green card, now Thailand's embassy won't let me apply for a visa because I don't have my legal papers, life is so unfair, it's everyone else's fault.
Cost of living varies significantly around the US. And CoL can vary somewhat in Thailand too, city vs rural. If you want to live on the 20th floor in downtown BKK in a penthouse condo, or next to the beach in a beach town, it will cost a lot. And if you have fancy tastes it's possible to save nothing in Thailand. The locals live on almost nothing, but most westerners will not be able to tolerate that lifestyle. Something to keep in mind.
