I am retired, traveling on a U.S. Passport. I would like to go to Thailand, staying / basing myself in Chiang Mai. I would like to be there for this coming December, January and February. I would like to get the easiest Visa for my stay - meaning I would rather not have to do any "border runs" or get in lines to get visa extensions. I would like to arrive in Thailand with all this sorted out and the appropriate visa in hand. Also I would like the possibility of being able to leave Thailand and return during this period of time. Not sure if there is one visa that would accomplish all this - hopefully there is. I would rather pay more for the visa than try to save money by doing extensions, etc. I would rather have a visa which allows more options but the above as the minimum. Not sure if this request for info makes sense but I would appreciate any assistance. My thanks in advance.
