From what I understand listening to the news today. Thai citizens no longer a required to fill out their TM form when stamping out of Thailand at the border. This will speed up the process at the immigration gates for Thai citizens.
TLDR : Answer Summary
Recent news reports indicate that Thai citizens are no longer required to fill out the TM form when exiting Thailand, which is expected to speed up the immigration process at border crossings. Comments suggest mixed feelings about how this change impacts foreigners, as they still must complete the TM.6 form. Some participants in the discussion express concerns that despite improving processing times for Thais, the changes may not significantly benefit foreigners passing through immigration.
