The owner of my new condo is Chinese and she is not in Thailand now. Therefore, she will report TM30 thru the internet. Then what can I do for myself? May I go to the immigration office with my papers and condo's contract and house registration only? or do I have to additional prepare?
My paper
Copy of passport photo page
Copy of passport visa page
Copy of departure card
Landlord's paper
Copy of the owner title deed
Copy of the rental contract
TLDR : Answer Summary
If your landlord is filing the TM30 online, you primarily need to ensure that they provide you a screenshot of the filing as a receipt. For your visit to the immigration office, you should bring your passport photo page, visa page, and departure card. Additionally, it would be prudent to include a copy of the landlord's ID card, the rental contract, and the property title deed.
