Level 3

Credit score

Apply for a secured credit card. Usually you need a minimum of $250 in a savings account with the bank or credit union. They will give you a credit card secured by thya that $150 balance. You should use it and pay it off regularly for at least a year. It's also good to increase the credit line by adding to the account and requesting increases. After one year you can request your balance to be converted to a true line of credit and your savings will then be available for withdrawal.
Also, Target and Walmart have been pretty easy cards to get.
Good luck.
