If they already have a business profile listed for you, do they ask for your business income again (not your personal income, your business income) or do they just ask for personal information?

Additionally, does anyone know if it messes anything up for one's original account if one applies for a card as part of a different business (I have done consulting work for another business, which actually has a separate Tax ID number as a corporation and might be able to talk the owner into giving me a title to allow me to apply for a card).
