Many things student credit cards
If a company asks you to shell out any money at all before your loan or credit line is approved (even if they say you are pre approved), refuse the offer and report the company to the relevant authorities. * Unethical billing practices. Predatory credit card companies sometimes try tricks like mailing you a bill on the bill's due date, meaning that by the time you get the bill, your account is already past due. Cancel your account if you can afford to, and send in your monthly payments on your own, without waiting for the company to mail you a monthly reminder. This list of danger signs is nowhere near exhaustive.
