Because your personal credit information is white and you don't have any loan records, it's not surprising that you were refused a credit card under such personal circumstances, nor was it because you went to a drug rehabilitation center at that time. For your personal credit information, it is like a blank sheet of paper. He has no repayment record and no credit record. In this case, the bank will not give loans, nor will it approve credit cards. Even if the credit card is approved, it will be limited to several thousand dollars.
