What is the best way to get my first credit card?

I am trying to get a credit card to start establishing credit. I am a college student. What is the best way to try to get one? Or what provider is the best like Mastercard or Visa, etc. I'm having a hard time getting one and co-signing is not an option for me at this point.

OK so i had no credit and i obtained 2 credit cards within the first 2 months of turning 18 (a few months ago).. i applied for a citibank mastercard platinum select card (citicards.com) and a chase visa student card (chase.com).. For the chase card, i got a 500 limit and for citibank i got 1000 credit line. I was surprised myself because I didnt have credit.. I didn't have a cosigner either…..So Good luck!!
