Sharing my experience with my first 90-Day Report at Koh Samui Immigration! It was super quick—took only 15 minutes (though it might depend on the day). I just submitted my original passport, TM30, and a printed copy of my DTV E-Visa. After that, they told me to head upstairs, waited about 5-7 minutes, and it was all done! Smooth process, no hassle. Hope this helps anyone preparing for theirs! 🙏
