Just got my retirement visa and bank, so im ok fir now. I am going to move residence in a few weeks from pattaya to korat to my home (wife's name) . I need to notify korat immigration and need to furnish whst to them?

Hi admins. I need your help about notification on changing address. I originally came from Phuket then moved to Nakhon Pathom in august. New landlord filed online for my notification of residence in Nakhon Pathom in August. Then in Oct 7 I went to Nakhon Pathom immigration to do 90 day report. My next report is Jan 4, 2021 but I will be moving to a new place in BKK this Friday. I have informed my new landlord in BKK about this but they dont have any experience on reporting. Questions are:

1. When should I go in and report my residence?

2. What forms do I need? Ive read about TM28 but im confused.

3. What requirements do I ask from my landlord?

TIA.
