Is it necessary to file a TM 30 if I return to the same address in Pattaya after visiting Bangkok for 3 days?

The necessity to file a TM30 upon returning to your registered address after a short trip within Thailand, such as from Pattaya to Bangkok, appears to be somewhat ambiguous. Many commenters suggest that while the rules indicate a need to file a new TM30 each time you leave and return, experiences vary greatly, and some individuals have reported not facing issues when returning to their original address. It is advised to check directly with the immigration office for your specific case, especially if you are staying in a hotel that might file their own TM30.
