I know on the AA thread it's recommended to open a AA Bus card with a new, about to start, business. Even if you already have a solid business, it's easier to just apply as 1 employee (yourself), no years in business, no income yet. That way Citi doesn't have any reason to ask you to prove anything.
I don't recall anything about this with USB. Any data points on applying for a Carlson Bus card with a brand new business? Because that's the only kind of business I have, and I'm not about to lie on the app.
