Yeah understand entirely! I have been doing my reports for almost 20 years. Since 2015 I(or the year when embassy letter was stopped) I have gone to the monthly deposit method and after the first year when they kept asking for additional documentation, I began providing them with a book each year, including yearly letter from my retirement office stating what I get each month, etc, a copy of the deposit from that office into my stateside bank acct, a monthly report of deposit of said funds into my stateside acct, my wire transfer request for each month, my Thai bank monthly report of transfer of funds from overseas, the two yearly reports fm my Thai bank showing the 12 monthly reports as well as the acct being mine only, plus a copy of every page of my local bank book updated on the day I go to immigration. When I gave that "book" to the IO, he laughed and said "wow very many documents!" I laughed too and requested he advise me if he needed more. He just laughed and 20 minutes later I was out the door waiting for the next year. I print all these on my printer so cost is minimal especially since there is no hassle from the IO.
