how long before requesting credit increases
12 months is not too soon to request an increase, but it depends on the lender and your credit score. typically most lenders want you to wait 6 months to a year at the most. the information you provided is rather scarce so i'll offer a little advice in general. if your credit is 650+ i would open another card AND ask for the increase. you typically want around 2-3 cards to boost your credit.
