Do I need to take my mother-in-law to the immigration office to register my address if she is the home owner?

@Steven *****

The TM28 is when you move to other address. On your other question, don't get confused, some offices want you to report with the TM30 slip they give you the first time, every time you leave the country and come back. But many other offices don't care, just go to Immigration, bring the TM30 and additional papers just in case they ask. If everything okay, you can ask the officer about the TM30 and how they want you and when to report. It is different at every office. Unfortunately not every body post the location of the Immigration Office they are using.

@Ste***

correct, if they don't say anything about it when you apply for a certificate of residence DON'T mention the TM.30 ;)

Please let us know. I move soon and will be using the same office.

I googled around and it appears that the Khon Kean immigration office doesn't care about the TM.30 (alien in residence) form. OR at least they weren't caring about it not that long ago.

Good Luck (y)

I had to get inlaw to sign one of these

It is down to the home owner to file tm30 and in the OP case if he does it on her behalf law they will want a form signed by her. I had to do this, pain in the arse it was.
