Hello All. 
I came to Thailand in July, stayed 2 months. I’m currently in Cambodia. I want to return to Thailand in October, but I want to stay as long as possible. I am retired. I do receive a nice pension from the US. What is the easiest way (least amount of paperwork, most cost effective ) to stay in Thailand for at least 3-6 months? Which visa? Is VOA w/ extension the only option?
I’m headed back to Thailand in early October.
