What are the requirements and processes for reporting the 90-day check-in on a Non O visa in Thailand?

Hi, I just extended my stay on Non O last month with all the very useful advice from here. 🙏 I understand I will need to report to the immigration office every 90 days if I continuously stay in the country ; yet am not sure of the followings :

1) does my landlord still need to provide the TM30 for each 90-day report ?

2) can I report online, or, will I need to walk in my local immigration office ?

3) any documents to present for each 90-day report ?

4) any fees for each report ?

Thank you ! 🙏🙏

Ps. Major Cinema near the BTS Ekkamai station offers 99 baht per movie on Wednesday evenings. (probably excludes those played at 7 pm) And in their men's room, a man looked at me as if he was quite hor....hungry. 😂)

The multiple-entry stamp is 3,800 baht. I got mine at Don Mueang Airport, I was told it's 4,000 baht before boarding my flight and thought the price just went up. Later I asked for a receipt of my payment, it types 3,800 baht....if you understand what happened to the price difference. 😅

Cannot lower seats on Thai Lion Air flights. 😅
