I am a graduate student in my mid-20s who has never had a credit card. While I have been able to get by without one, I have finally reached a stage in my personal and professional life where not having one has become a real inconvenience (when trying to reserve a rental car, for example). I would be grateful for advice on the cards, or kinds of cards, that I should seek or avoid for a first credit card — as well as whether I'm likely to receive one, and (if not) what I can do to make myself a better candidate.
