If I come back to thaialnd on Saturday, how could I do the TM 30? The immigration is closed on the weekends and I wonder if it is okay to do the Tm 30 on the immediate monday. Your views and advice will be highly appreciated. Thanks in advance.
TLDR : Answer Summary
If you return to Thailand on a Saturday, you can submit your TM30 report on the next business day, which is typically Monday. Many users confirmed this practice, noting they have done the same without facing issues. Some immigration offices may even be open on Sundays for TM30 reporting, but if they are closed, reporting on the following Monday is acceptable and will not result in any fines.
