@Russell ******
it’s a two part process. The initial Non O visa (90 days) does not need “seasoning” of the funds - although your local office may insist. Most won’t.
When it’s time to get the year extension then funds need to have been in for 2 months. They also must stay in for 3 months after. The balance can’t go below 400k for the rest of the year and would need to be back to 800k two months prior to your next application.
