Do I need a new TM30 if I leave Thailand and return while staying at the same place?

When returning to Thailand after leaving, you typically need to submit a new TM30 form, even if you stay at the same address. While this is required per immigration regulations, the enforcement may vary by local immigration offices. Some expats report differing enforcement practices, with some offices requiring it for all entries while others may not check rigorously. To avoid issues, it's advisable to prepare the TM30 in advance or check directly with your local immigration office for specific requirements.
