the handout from Chaeng Watthana only includes 2 mnth prior and 3 after application approval as in the first year, but i don't see anything about following year being different for the full balance requirements
i think upon receipt of the first one-year extension, you must continue to maintain the 800k but only for 3 months, then it can drop as low as 400k, and then it has to be the full 800k again for 3 months before you apply for a new extension. If all that while you show monthly deposits of 65k+, you can convert to the monthly deposit-only method for year 2 and thereafter. Please correct if I'm wrong, I'm in month 5 of year 1.
I've used remitly and Wise although now prefer Xe. My US bank can link to accounts and do transfers but not internationally (at least Thailand anyway). Although I confess I just use the mobile and web apps and could maybe use the messaging to ask if they would set up the xfers. I just went the easiest route (I felt) to use the services.
i was not able to do an international transfer btwn thai and us banks without using a service. I guess I don't know what banks provide that, especially with the same ease.
