It seems that Immigration is now rejecting online 90 Day reports when your last TM30 registration was not in the place where you are living/applying.
My last TM30 at the place where I live dates from January 2020, before Covid. Since then I've only traveled within Thailand and this was never a problem with 90 day notifications, also not for my most recent one 3 months ago.
But today the system gave me a 'rejection' because it found that my most recent TM30 registration was close to two years ago in Bangkok. This is interesting because I stayed in a whole lot more places since then all over Thailand, but I guess none of those did a TM30 report. ๐
So... People may want to think twice about checking into hotels with their passport because that means having to do another TM30. Which for some people is a hassle when they have to ask a landlord to visit the immigration office, etc.
(Of course if you have a login to the online TM30 site or app then it takes just 2 minutes to do another TM30 when you return after a holiday, so it's just a minor hoop to jump through. )
TLDR : Answer Summary
A recent issue has arisen where online 90 Day reports are being rejected if the TM30 registration at the applicant's current address does not match the last reported location. This became apparent when a user experienced a rejection despite having traveled and submitted 90 Day notifications without problems previously. It highlights the importance of TM30 compliance and the variability in immigration policies depending on local offices in Thailand. Users are advised to ensure their TM30 registration is up to date and accurately reflects their current living situation to avoid similar issues.
