do all cards from the same issuer (citi cards, boa cards, chase cards) all have the same qualifications to get the card. Like do the banks look for the same credit criteria to approve?
They do not all have the same qualifications. One example is the Citi Platinum AMEX - if you make less than 50K a year then you don't qualify. Each CCC has their own internal levels, even if they are both "prime" cards one could be *easier* to get than another.
