Just a heads up before Robert Lagus deletes this. If your reporting office is Chumphon, and by law you are now requiring you to report on arrival back home. they didn't care before. If you stay in a hotel down the street on the beach and check in and out you still need to inform immigration you returned to your house. I got burnt for 2000 baht today for my last trip to Bangkok last week.
TLDR : Answer Summary
Expats returning to Thailand, especially in Chumphon, must adhere to strict immigration reporting requirements, including notifying local authorities of their return within 24 hours. Violations can result in fines of up to 2,000 baht. There are inconsistencies in how these laws are enforced across different immigration offices in Thailand. Many expats suggest having their Thai spouses handle hotel bookings and check-ins to avoid drawing attention to their immigration status, as hotel staff are legally required to report guests' passport details to immigration. It's crucial for expats to verify the local rules and stay informed of reporting obligations, particularly if traveling frequently.
