For planned and intended Departure Date Leaving Thailand, just put the same date as your Arrival Date into Thailand, then you do NOT have to fill in Any Thailand Address detail information on the TDAC Website
Would you to kindly share a scan or photo of this Thai Immigration Entry Stamp at Chiang Mai Airport for your DTV E–Visa Entry Stamp today, as this should be a DTV E–Visa Red Entry Stamp from 22 NOV 2025 to 20 MAY 2026, but you only received a permitted stay duration up to March 2026
At Thai Airports, particularly at Suvarnabhumi Airport where there are Thai Immigration ABC E–Gates in use, a passenger does not have to use the E–Gates....
So, did you apply for and receive your DTV E–Visa from the Thai Embassy in Hanoi back during February 2025 or recently this month during November 2025???
