@ waledog,
I did my flight training in the US and was lucky enough to win a greencard in the lottery. For eight years I had to regurlarly endure the "Why do you steal US jobs, we can't go to Europe if WE wanted to" and other lines along that subject (this in a country that is founded on immigration and proclaims to be so tolerant).
When I went back to work for a commuter in Europe I was very suprised to see alot of (outside EU) foreigners including US nationals working there. I moved up to my coutries major flag carrier and the exact same. So whaledog US persons can work in Europe, It is not as one sided as you think and at least the foreigners working in the states have the courtesy to learn the local language and not complain about the opportunity they have been given which is more than I can say of many off your countrymen in my company.
