Well to give you an idea, my instructor was form France, and the procedures to get a CPL are somewhat close. To be a CPL in Europe, (depending where) in theory you are 3 courses away from being a tech.engineer. The theory was outrageous...He was telling me in France you fly more with your head than with your hands. That’s one of the reasons he why he left Europe. Didn't like that idea and don’t forget the prices, allot of European pilots come here to learn to fly due to the high prices they pay for their training. I.e.: C-152 per hour might cost you somewhere around $200.00/hour and don’t forget the high priced landing fees. Might cost you easily $100K to get a commercial-multi-IFR
I would look into converting to the US license.
