You may be able to continue using your student credit card after graduation— some issuers some issuers, like Discover, may even upgrade you to the nonstudent version of your card. That said, you should consider looking at other credit cards once you’ve built up your credit score in the “good” range or have a FICO Score of 670 or higher. At that point, you may be able to qualify for one of the best credit cards, which have better rewards and perks.
