Question/ advice wanted from Chiang Mai residents (or Tod Daniels) that are holders of non immigrant O visas and extend annually based on retirement. Do you report to immigration to update your TM30 every time you return from domestic travel? (Assuming you’ve provided your passport to check in at a hotel). If not, have you ever been fined when doing your next 90 day report? We are taking our first trip south since getting our first extension based on retirement. We are doing a 90 day report about two weeks before we leave so wouldn’t have to worry about it again til February but having read horror stories about 6000 Baht fines for not having an “up to date” TM30, I thought I’d ask the question.

I find this the rule absolute most asinine thing I’ve ever heard of because obviously if you’re checking in for a 90 day report in CM and there’s a valid TM30 on file with your passport that was filed legally on the day you took residence in this province, it’s obvious you’re not “staying” in another province but rather, you took a holiday, stayed at hotel and they followed the idiot law by filing a TM30 for every guest that checks in.

From the responses in the other groups it seems most think it’s not for domestic travel but the ones I trust say it is the law but it’s not often enforced
