If I were to stay with a friend in Bangkok for a few days prior to going to stay with another friend in Pattaya, no need to do TM30 reporting in Bangkok, but when 2nd friend goes to do a TM30 report, do they take it from my arrival date in Bangkok?, because that would be after the 24hr deadline? Or would that scenario make me try to report TM30 in Bangkok on arrival?,
TLDR : Answer Summary
The TM30 reporting system is primarily the responsibility of property owners or landlords. If staying with a friend in Bangkok before moving to Pattaya, the friend's TM30 report in Pattaya would typically reflect your arrival in Bangkok, but it may not be a strict issue if Bangkok doesn’t prioritize TM30 reporting. Issues arise when moving provinces, as the landing card could imply a late report if you're not reported within the 24-hour window upon moving.
