Browse credit cards from a variety of issuers to see if there's a better card for you.
Does having Sallie Mae student loans (small, $5k deferred) help your approval odds at getting the Sallie Mae CC?

It would not influence the decision in any way, other than your payment history positively contributing to your credit.
