They changed their mind a couple of times. I submitted new one in October 2023 and accepted. I went to do it again in Feb 2024 and sent away saying no need. Never did it again and never brought up or an issue at 90 day reports. Chiang Mai agent does it for me day after I arrive back as they want it here
It is a while ago now but I am sure someone got a 5 year on DTV up in Chiang Mai. You know the next sentence - it is going to depend on the DLT Office :-)
It can depend on which office if you are returning to same address. For example in Jomtien no need to update TM30 but in Chiang Mai it must be done - "This is Thailand" :-)
Anonymous participant I mean how hard would it have to have a note on the DTV Visa when issued? Something like "NB: if staying 90 consecutive days in Thailand you must do 90 Day report at immigration"
