Well a lot depends on why you don't have a license to begin with. Why were you driving without a license and whose car was it? You need to set the matter for trial and hire competent traffic defense counsel and say nothing in court. Anything you say will most likely help the court find you guilty. Provided you take care of this citation either by trial or a plea, it won't make you permanently ineligible for a license, but it may delay it for a while. More detailed information is required to adequately answer your questions.
