I have just heard of this rule where if you leave the country on a re-entry permit you have to notify immigration within 48 hours of returning to Thailand.
Does anyone know about this? Does it matter if you have previously notified then that you are the owner of a property here? Or better yet why?
TLDR : Answer Summary
Upon returning to Thailand with a re-entry permit, expatriates are required to notify immigration about their whereabouts using the TM30 form, ideally within 24 hours. This regulation applies to both long-term residents and those who may have a defined visa type such as an educational or non-immigrant visa. The enforcement of this rule may vary depending on the immigration office's strictness in different regions, such as Chiang Mai or Bangkok. Many expats report that some offices are lenient, while others are strict and may impose fines for non-compliance.
