Is TM30 required for the 90-day immigration report in Thailand?

Ask the staff at 711 may be better

You need to have at least a current registration in the TM30 system for the address you use for your 90 day report.

Tm30 is required by law within 24 hours of arrival @

You need TM30 + prior 90 days report paper . If you lose the latter , need to go and ask at nearest police station

Immigration's site will tell you exactly what you need to bring. TM30 is on the list along with a TM47.

People will say can I break the law to just get away with it? Yeah that’s what it is

Yes, it is needed. You can get one from a hotel by booking in, or from your landlord, if not illegal...

You need to ask your landlord to submit a new TM30 report each time, because the TM30 information may only appear in the immigration system for 7 days. For example, if you need to complete your 90-day report, ask the landlord to submit a new TM30 within 7 days before you do the 90-day report. An expired rental contract alone may not be sufficient.

Tm30 has nothing to do with rental agreement, where ever you are staying, the tm30 has to be active. Its not your reaponsibility, the host has to do it. Ask for the tm30 receipt, you can do 90day report with it. Im not sure, but even if you had rental/hotel/something but they didnt make tm30 of you, you cannot do 90day report (maybe, if you pay them or agent), an agency might be able to, I advice you to go for an agent

Yes you need the TM30 to do a 90 day report.

If you're leaving soon, just skip the 90 day report. It's irrelevant when leaving the country.
