Back in 2013 after visiting Thailand twice in 2002 and 2006 I decided to give it a shot and move permanently. I came as a tourist, went back and forth from Vientiane and KL for a year (a lot of fun). After that I applied for a 1 year Thai language study visa which was ridiculously easy to obtain and so cheap (16,000b plus 1900b for every 3 month extension).
in 2015 I got married and got my marriage extension. Despite that I still loved visiting other countries.... Malaysia, Laos, Japan.... so living on a tourist visa would have not bothered me one bit. However, during that time there were a lot of old grumpy men on this forum whining and whinging about backpackers and how Thailand should crack down on them.... and they did eventually. To me this animosity towards younger generation of travelers was really stupid as I knew the more "rules and regulations" would be coming soon. I remember in 2018 and 2019 while travelling there would always be some old guy in front of me being questioned by immigration about his frequent visits to Thailand. Meantime the covid happened so all this was put on hold.
So, what old people wanted old people got. Enjoy doing your tax returns while doing your 90 day reports, begging for visa extensions while having zero rights in this country. I'll be out of here by April.
