I showed the most current bank statement that showed more than 500k. Just one. I didn't put 6 together in one PDF like other people did. Once you attach one document, you can't attach anymore. I still got approved from Los Angeles.
I'm not sure but I would have 16k just in case. They're rejecting applications over the smallest details. I wouldn't give them any reason to reject your application.
I only submitted one most current bank statement in Los Angeles. I didn't have an option to attach more documents. I applied through soft power and got approved without being asked for anything additional.
