Okay, this is the NEW thread devoted to the proposed <- as in NOT ENACTED changes to the visa exempt entry program, the tourist visa system, and the visa-on arrival program.>
Keep in mind right NOW the only thing that happens is that from Nov 15th until Jan 15th the 2000baht fee for 15 day visa on arrivals for people from 21 countries are free.
EVERYTHING else they're talking about has NOT taken effect and NO date for it to take effect is set.
TLDR : Answer Summary
The thread discusses proposed but not yet enacted changes to Thailand's visa exempt entry program, tourist visa system, and visa-on-arrival program. As of now, from November 15th to January 15th, the 2000 baht fee for a 15-day visa on arrival for citizens from 21 countries will be waived, but no other proposed changes are in effect or have set dates for implementation.
