Hello everyone. My inquiry is about the requirements and process for the 1 year extension of stay application (based on retirement). I hold a US passport and am currently in Bangkok on a 90 day non-o Visa based on retirement. The stamp was obtained on 9-Nov-2021 (from CW), and expires 6-Feb-2022. I obtained the 90 day non-o Visa stamp using the banked funds method (e.g., 800,000 baht transferred from my US bank account into my Bangkok Bank account on 21-Oct-2021), and completed the TM30 using my current Bangkok address. I also now have a new 1 year lease agreement beginning 15-Jan-2022 for a condo (at a new address) in Bangkok. In addition, I would like to apply for my multi-entry permit at the same time I apply you my 1 year extension of stay.

What I want to better understand are next steps and preparation, and what can I expect when going to CW to apply for my 1 year extension of stay (i.e., when should I apply, what do I need to have in hand; is there a waiting period, etc.). Thank you in advance.

Can I go to Chiangwattana for O visa renewal, reentry permit and proof of residency certificate (for driving license renewal) or is some of this done at Muang Thong Thani?
