What should I do if my hotel cannot perform the TM30 online registration due to system issues?

depends on immigration office /province. In Bangkok, you cannot file TM30 at police stations. You need to go to Immigration office if reporting in person.

OK, I agree that in the specific case that "you" are also the possessor, then you should report yourself... Bit of a bugger if you have two places you own (or possess) such as a weekend place, especially if you can't report on-line (since Immigration offices are closed at weekends).. I've seen reports that people in this situation have been told they should simply choose which residence they wish to be formally registered at. But since my reply was to the OP, who specifically states she is staying in a hotel then this situation is not relevant to her particular case.

Not exactly correct... As the form says as its title, "NOTIFICATION FROM FOR HOUSE-MASTER, OWNER OR THE POSSESSOR OF THE RESIDENCE

WHERE ALIEN HAS STAYED", in case You as a possessor of the property, you also have the responsibility to be reported.

You have to be reported TM30 every single time you change the address.

Your landlord or property manager is the one who is supposed to report TM30 for you. But you also can do self-file at some immigration offices.

For example in Bangkok, self-file works as this post

3/permalink/7/

In other provinces, you can refer the post above and check the local office how you can do.

IF they're doing it by post they'll get back the bottom of the TM30 form which is your receipt

IF where you stay files one for you it will look like this

the manager can provide you a copy of the TM 30, along with a cover letter. Just ask , they're normaly very accommodating.

While the law is indeed clear about when it has to be done, this is the first time I know of the online TM30 system (which all the hotels and guest houses have been using for over 10 years) has been down like this :/

I dunno if they'll cut slack because of it

Sound like OP's hotel is aware of TM30 and they do usually. the point is they cannot do it online NOW and give OP the receipt because of system down....
