Choose a card depending on your current credit score. Our credit card navigator can help you to find one.
Since you are planning to file a bankruptcy, there is a risk that the credit issuer will close your account once it sees the bankruptcy record in your reports.
You can apply for a secured credit card. There are more chances to keep it during a bankruptcy because it has a collateral deposit. The minimum credit line for a secured credit card is $200. If you feel you can handle a bigger amount of credit, just increase your security deposit.
Make sure you do not owe a balance on the card when you file the bankruptcy. That may help you keep the card.
