Instead of DTV I got a Multiple entry tourist visa from Hanoi. I provided 4 months of banks statements with 1mil THB, income of 700K+ in 2025, 6month muy thai course from a reputable gym. I saw a guy (girl?) approved today in Hanoi with a weaker application than mine (1 month course, 3 month bank statements, no income). Make it make sense.
edit: I am going to delete this post in a couple of days since I can see only negative things coming my way. I just made it to vent mainly but also to offer something back to this group.
