Hi All - I'm new here and have read a lot but all the details and terms leave me a bit confused so if someone would give me some help it would be much appreciated. I've been to Chiang Mai briefly and plan to return this fall for 90+ day stay. I'm American, 50+yrs old (to say the least) and wonder what is the easiest / least complicated way to handle visa issues for this stay. My thanks in advance.
