Before You Apply

‍

• Know your credit score - Most cards list a recommended credit range for approval.
• Review issuer rules - Some banks have restrictions on how many cards you can have or how often you can earn a welcome offer.
• Define your goal - Decide if you're looking for travel rewards, cash back, or a tool to build credit.

Application Strategy

‍

• Choose the right card for your profile. Some cards are for those with fair credit, while others are designed for small business owners.
