What are the requirements and experiences for obtaining a DTV visa from the US, particularly from the Los Angeles consulate?

any dividend investors in the US stock market successfully got their DTV visa? specially if you don't keep much money in the bank but only transferred the 500k Thai Bhat amount to "qualify for proof of funds in bank"? appreciate if you can give me feedback on how it worked for you and which category you applied under, and if they scrutinized a fresh large transfer coming into bank or not or didn't care as long as it was there and "recent date"? asking for Thai consulates in USA only, particularly the Los Angeles one. thanks!
