Have you thought about maybe flying as a career? Maybe an airline, corporate operator or your own flying business is in your future, but you first need to obtain your FAA Commercial Pilot Certificate. FAA Part 61 Subpart F 61.121 through 61.133 lists requirements, privileges, and limitations to the certificate. There is a good chance you may have already fulfilled some of those requirements. You are especially ahead of the pack if you already have an instrument rating.
