DP: Approved for an Alaska biz card at ~15/24 after having previously closed another Alaska biz card approximately 2 months prior. In both cases I applied under different EINs/businesses, and in both cases BofA requested a CD. It's tough to say for certain, but I suspect that anti-churning rules for card are based off the business credit report rather than the personal one - and that the BofA personal rules don't apply to the card.
