Hi! Since joining this forum I have done a lot more research and believe I will learn more when I visit Chiang Mai in June. At this stage I think the best thing for me to do would be to stay for about 25 weeks a year. Could anyone advise me what the best visa would be for this length of stay. I think staying this length of time will sort out whether I should stay longer or retire in Thailand. Thanks. I find this forum very helpful.
