I've read on this group many conflicting posts regarding the TM30 - do/don't I have report my whereabouts after my absence from my last registered address with Thai Immigration.
My experience yesterday - Fri, 03/01/20.
I have a Retirement Visa, I'm currently registered with Thai Immigration as staying in Korat (I have a small home here), I spent 4 nights away from my home, I phoned-up the Thai Immigration office in Chok Chai prior to my return to my address in Korat, their TM30 reply: "yes, you must report your return to your address within 24 hours"
However, I told them that "I wouldn't be arriving back at my home until Fri evening, & it would be too late for me to report that day, could I report Sat morning instead, no, holiday here Sat, you must report Monday"
So, the TM30 Rule is still in force here!
