Is the TM30 necessary to complete a 90-day reporting in Thailand, or can I solely use the TM47?

The discussion focuses on whether the TM30 form is required when submitting the 90-day report in Thailand or if filling out just the TM47 is sufficient. Experiences from other expats suggest that it may be necessary to present the TM30 during reporting, especially if not staying registered at a friend's address. It is advised to consider registering at a hotel for proper documentation.
