Who is responsible for TM30 registration when hosting foreign friends in Thailand: the homeowner or the guest?

And people wonder why I close TM.30 posts as fast as people ask about them.

We're done,

Good Luck to the O/P and their friends, (y)

For 3 weeks?? Seriously? “Abroad” from where? I stay the night I arrive at a legit hotel, and then forget about it. Do you really think immigration is THAT concerned about chasing away tourists on stamps?

I see some questions: AirBNB or other websites do not visit Immigration for you. Yes it is a mandatory since 1979, but not enforced by all Immigration Offices. But I'm the owner does not exclude you from the law. In this topic I explain, answered lots of Q&A, how to register on-line and more help for every foreigner who like to stay at a private address in Thailand. As there are over 70 Immigration Offices, I did not make a separate database of every office and their enforcement and yes even this enforcement changes. Check with you local Immigration Office 3/permalink/5/

Is it a mandetory? Last 3 years i never did. I went out of thailand several time and come back. Also extended my visa, never asked.

At Chiang Mai immigration you go upstairs to the 3rd floor. You take their passport along with their TM 6 which is their departure card. You fill out a form and then you get a notification of where they are staying.

I was told this last week at immigration. You can do it aslong as your name is on the rent agreement.

I was told this by immigration.

Someone can please correct me if I am wrong?

I will be doing this on Friday for a friend

Personally I don't register people who aren't going to stay in the country for longer than their visa/if they never have to visit immigration. The problem comes if they visit immigration and they see the person hasn't been registered they fine you. In cases like in NST apparently we get fined 500 baht per day up to the value of 20 000 baht

And who did your TM.30 form?
