Before you sit down and fill out a credit card application, make sure you know your personal credit score (remember to check your score with all three major credit bureaus), as well as what features you want most in a credit card and the best options on the market with those features. It’s also important to know the application restrictions and rules for the specific financial institution that issues the card you want. You don’t want to waste time and a hard credit inquiry on a card you won’t be able to get.
