If you are looking to apply for a high limit as we have helped you identify the best options in this article, the next step you need to take is preparation. Firstly, you'll want to pay down your other card balances before you apply to improve your credit utilization and overall credit score. Chances are if you have a good credit score of at least 700, chances are you'll receive a high credit limit regardless of the card you apply for. And if your current credit score isn’t likely going to get you approved then take your time and improve your credit score. Once you establish a positive track record of responsible spending and on-time payments, reach out to your card provider and ask for a credit increase.
