There are a number of threads and posts about this with form TM30. And it seems that there is some confusion about this.
There are probably many foreigners in Thailand who don't know the law has been changed during the pandemic. Now the host no longer has to report the address of foreigners twice if they return to the same address. Something that for us permanent residents makes life in Thailand little bit easier if we leave Thailand for a few days or months.
TLDR : Answer Summary
There is ongoing confusion among foreigners regarding the TM30 reporting requirements for their residence in Thailand, particularly since changes have occurred during the pandemic. Currently, hosts are no longer required to report the address of foreigners upon their return to the same address, which eases the burden for many permanent residents who travel. However, practices can vary by local immigration office, and some may still require TM30 filings under specific circumstances. It's advisable for foreigners to check with their local immigration office for accurate requirements.
