They could check if they wanted to. You are supposed to report within 24 hours of each arrival. But they wouldn't pick it up unless you went for an extension at an office or had to do some reporting like with the long term visas. Just leave before expiry of the visa stamp and you would not need to visit an office. Unlikely they would come and do a spot check for a tourist visa. In that case you would never be fined. If in BKK Tod says they don't care.

It is only needed if you have to make an extension at SOME immigration offices. Ie Pattaya and Chiang Mai require. BKK not required. The form can be downloaded (search TM 30) or go to an immigration office. Should be owner of property that does it (unless that is you) You have a METV so you won't need it will you? just leave and re enter...?

Hi Tanya. No only the completed arrival card handed out on the plane is needed. Jeremy mentioned a TM30 form above, but he meant the arrival card. TM30 is just to register your address for people staying in private residences (ie not hotel).

I take it you will be in a hotel? so no issues with having your address registered.

correct. Many people do not consider this and buy IDP time and time again.

An IDP is only valid for 90 days for insurance and is not designed to be used long term. Repeated IDPs while living in Thailand is not recommended. Should go for the Thai licence.

Tm 30 is done after arrival at immigration....if needed...

Andrew is talking about Tm6. Luke is talking about tm30.

Do you mean TM6 card??

Are you in a hotel or residence? They seem to be clamping down on this TM 30 thing in some places....probably mostly in Pattaya though.....catching a lot of people out recently if Landlords don't register you.
