By the way, in that helicopter avionics example...if you eliminate the H1B then all 7 of the 9 Americans get fired. The top 2 Americans move with their company to Portugal or some other country and hire 15 local workers to replace the 7 Americans who were fired.
What kind of threat is that? The USA was fine without H-1bs and you know what? The USA would have been fine if you had stayed in your third world hell hole.
