Only those silly enough to get a Tax ID number! I can't speak for other countries but the Australian DTA protects Australian Tax Residents from paying tax in Thailand on money already taxed.
Australian embassy and consulate is not asking for it. It's not on the original criteria. Perhaps a few rogue embassies are doing this. I know three people already have made the switch
You are obviously a sensitive little snowflake going into emotional meltdown. You have so much to learn about visas in Thailand. Go to school?? Jesus Christ!!! 😂😂😂. I'm telling the OP the easiest way to get the DTV, and you're telling him he'll have to go to school!!! 😂😂😂
