I have a credit card, probably the first one, which I took out 10 years back. But, I want to close that account since the interest rate is relatively high. But, I know that closing an old credit account can affect my credit score. But if this true, will I not be able to close my oldest credit card account ever? Will it continue to appear in my credit report for 10, 20, 30 years - as long as I use the card?
