Step 1
Maintain a good credit history. Pay your bills on time. Missing a payment on a loan or another credit card will hurt your credit score and lessen your chances of getting a high-limit credit card.
-
Step 2
Diversify your lines of credit. Don't have only one type of credit, like a car loan. Try to maintain several different types of credit in good standing. You could have a car loan, a department-store credit card and perhaps another bank-issued credit card with a lower limit.

Step 3
Keep your balances low to keep your credit as high as possible. This is called having a low debt-to-income ratio. Try to pay off the credit cards you already have each month, and don't take out too many unnecessary loans.
-
Step 4
Make sure your income qualifies you for a high-limit credit card. Even if you have excellent credit, if you do not meet a bank's minimum income requirements, you will not qualify for a high-limit card. You must have the income to pay back the money while meeting your other financial obligations.

Step 5
Ask a friend or relative to co-sign. If you do not meet the requirements on your own, having a co-signer can strengthen a weak credit history or allow you to meet the bank's income requirements.
