My sister and her husband are coming for a month visit, we have a multi years rental apartment in Pattaya. They hold US passports, what documents do we need to submit for their proof of staying here, the 24 hours reporting. Thanks so much.
TLDR : Answer Summary
For your sister and her husband visiting Pattaya for a month on US passports, a TM30 reporting is necessary to notify the authorities of their stay, particularly if they might extend their visit. This can often be handled by the landlord or condo management online. However, if they are not using immigration services and their stay is strictly under 30 days, there may be no requirement for immediate reporting. It's recommended to confirm this with local immigration authorities or the condo management.
