MTT started aggressively checking tm30. Make sure yours is up to date or your going to have a very bad day. This is a call to all the people on month to month airbnb leases that think the little "for visa purposes "pdf from airbnb is going to cut it with immigration.

TLDR : Answer Summary
There has been an increased enforcement of TM30 registration in Thailand, particularly impacting expats on month-to-month Airbnb leases. It is crucial for renters to have a signed lease contract that includes their name, passport number, and full address, rather than relying on the temporary documents provided by Airbnb. Recent discussions highlight experiences with immigration officers checking compliance and the potential fines for landlords if TM30 forms are not properly filed. It is indicated that even those on tourist visas are required to adhere to TM30 regulations.
