UPDATE from Pattaya/Jomtien Chonburi Province Immigration...reported by the Pattaya City Expats Club:
THIS IS FOR PATTAYA/JOMTIEN ONLY...
We received recent first hand reports that Chonburi (Pattaya) Immigration is now requiring the TM.30 Address Report be filed by the homeowner/landlord/possessor within 3 days of a foreigner's return from a trip outside of Thailand, but still does not require it if the travel is within Thailand and you return to your previously reported address.
TLDR : Answer Summary
Recent updates from Pattaya/Jomtien Immigration indicate that the TM.30 Address Report must now be filed by landlords or homeowners within 3 days after a foreigner returns from international travel. This requirement does not apply for domestic travel within Thailand if returning to the same address.
