How long after a significant salary increase will I be eligible for an overall higher credit limit?

If I have 10,000 in available credit and my income doubles how does this effect my hypothetical "credit limit".|||Pay your credit card off in full every month and the credit card company will automatically increase your limit every 6 months to a year.|||Income doesn't have as much to do with your credit limit as does your payment history. You can always ask for a higher limit; you may get it.
