When should I file TM28 after moving to a new condo in Bangkok with a Non Imm O Visa?

Hey I joined recently and think you guys are doing terrific service through this group.

I have a question. In early July I expect to change address (still in Bangkok). Will be renting condo in the city. I am aware that landlord will need to file a TM 30 form and will do quite quickly I expect. The condo management are well organised.

I have Non Imm O Visa Retirement due for extension end of September (current one expires 14 Nov 2020)

I’m not sure about when I need to advise Immigration myself with TM28 form. And do I need to go into the Immigration office at CW?

My 90 days report won’t be due until a couple of months later so maybe difficult to combine with that due to timing.

Ta in advance.

Richard.
