Has anyone successfully used the 65k per month transfer plan with Bangkok Bank for visa extensions in Jomtien?

Hey guys, following up on this gentleman‘s question, I have the same question as it pertains to the 800 K. I’m just starting this process as it’s my first year in Thailand and I was told that I would need a letter from K bank confirming that there was an intermediary transfer since WISE apparently also uses K Bank for the initial receipt of funds before it turns into a domestic transfer to your individual account. The letter should highlight that the funds came from overseas to mitigate the intermediary coding. So the question I have is whether anyone has done this at immigration and what, if any, were the hassles at the time of renewal? Some people seem to have no problem at all. Thanks. 

I tried, but last year in September they froze a ton of accounts, mine being one of them. I did a September Swift transfer to an account at Siam Commercial Bank but immigration didn't like the variation nor the paperwork issued by Siam Commercial Bank to prove that it was an overseas transfer. I'm going to try using Bangkok Bank again this year for the 65,000 monthly transfer. In addition the fees charged by Wise are about 500baht vrs a $1,950 hit on the exchange rate through Swift. I'm also going to keep a 400,000 baht balance in the Bangkok Bank account which seems to be the magic number to get the paperwork through Bangkok Bank and keep 800,000 with SCB until I see an official acceptance of the monthly method. 🙂 All part of the costs to retire here

Is there a question behind that?
