Is a TM30 required for a 30-day tourist visa extension in Thailand?

The necessity of a TM30 form for extending a 30-day tourist visa in Thailand appears to depend on the specific immigration office. While the user successfully obtained an extension at the Laksi immigration office without the TM30 by providing a lease agreement, responses from others indicate that this requirement can vary across locations. Some offices insist on the TM30 regardless of circumstances, while others may not. Therefore, it's advisable for expats to obtain a TM30 to avoid complications, as practices differ significantly between offices.
