BOA internet banking 에 들어가면 바로 “request a credit line increase” link가 있는데요?
“Your account performance and credit status will be used as factors in our decision for a credit line increase on your personal account. This request will not result in an inquiry to your credit report unless you are notified that it is required, and the decision will not have any impact on your credit history.” 라고 나오네요.
