First of all, pay your bill in full each month. I don't know where you got the idea that not doing so will help you. In fact, it will do exactly the opposite. If you can't afford to pay your bill each month with a low limit, how can they give you a higher limit? Not to mention, taking advantage of the revolving credit is going to cost you a lot in interest.

I would say wait until you have a year of credit history. Then, when all your balances are paid in full, contact Capital One and ask for an increase.

If that fails, then try Discover, I have heard that they are more willing to gamble on people with short credit histories. Credit unions may do so as well.

No more than one or two applications every few months.
