@Greg *******
I’m not going to ask them for a copy of their passport page just because you want to see an evidence. You’re required to do soft power activities while in Thailand on a DTV visa granted for soft power activities or you’re risking your entry, or even your visa just like them. You got 99% chance that you won’t be even asked questions about it. Your visa your game, do what you want with it. Your initial comment is a hearsay. Cheers
