I've been here since the start of 2022 on an agent-assisted non-O and two subsequent extensions. The Full Monty not hand-holding.
Agent is Pattaya-based. I moved from staying in hotels in Patts & Bangkik to renting a condo in Bangkok. Condo office did TM30 online. I paid a Bangkok-based 1K baht to do my first TM47 at CW, including pick-up and drop-off of passport at my condo. Went without a hitch.
Subsequent TM47s have been done online. I changed condos a few weeks ago just before my latest TM47 was due. Condo office did new TM30 online, I waited 4 days then submitted the TM47 visa the extranet. Approved same day. Simples.
Agent has confirmed that they don't update my address as part of the renewal process so I'm not expecting any issues at the end of May when my next TM47 is due.
So, no downside at all.
