How long do I have to wait to reapply for this credit card?

I am almost 21 and I really need to build credit so I can have established a credit score when I graduate from college. I recently applied for a credit card, but was denied for having no credit history. I then applied for another card, but was denied for submitting multiple applications for credit. That is the ONLY reason they gave for me being denied. I really need to build credit and I don't know what to do. How long should I wait before reapplying for this card?|||Thing have been tightened up for young people getting credit cards because so many credit card companies were signing up students for debt that they couldn't hope to repay. If you have a job, so that you can show a source of income, apply for a department store card first.|||Its kind of hard to understand why would they do that to you .For me wasn't any problem i never got any problem with that "They do it to me right way .maybe its just that a bad person try it again|||What's the rush?


Have you considered a car loan? Much easier to get.
