Thats why I said she ' needs to BE registered' and not she needs to register herself. BUT it is her responsibility to check that the Landlord will register her as many don't. So when the tenant goes for the extension, and it was not submitted within 24 hours, they get fined on the spot and have to register the TM30 themselves(as you indicated). (which has been happening very regularly at some offices). If you assume the Landlord submitted it then you will have issues at extension time.
In that case tell Landlord to register you with a TM30 form if you are worried, at the local immigration office. Can't do it at the airport as far as I know. Can download beforehand and fill it out. Should be the Landlord but many tenants end up doing it themselves.
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).
