Welcome to the USA BAPilot
Dear SA Pilot,
I've worked my way up the ratings chain, much the same way you did, and I did work as a dispatcher for several foreign airlines in the 1990s. No, Iberia wouldn't hire me, Aeromexico wouldn't accept a "Gringo" and Aerolineas Argentinas and TACA offered me first or Business Class. However, my granddad jumped off a freighter in NY harbor one day, my mom came across on a clipper ship ( a Pan American Clipper) and my wife also CHOSE to make this country her own. So I say, get your 737 time, come on over, and join the rest of us in making this the great country it is. You might want to consider applying for other National carriers, such as AirTran, Frontier, or even JetBlue (if you don't mind flying a Scarebus) Hope to see you in the cockpit one day with your new US passport. Welcome Aboard
