Hera Bhai when u apply for a credit card your soon-to-be creditor will perform a hard enquiry on your credit and too many of those hard enquiries will impact negatively on your credit score. you said you had applied Many credit cards in the past and got rejected so one more hard enquiry can further damage your score or in some case may make you ineligible to apply credit cards for next six months. That's why  if I were you I would go to the nearest bank and would have some words with my personal banker, they can suggest you what exactly you should do looking at your history.
