It depends on what part of the country you're in. Oklahoma most of our pipeline welders are American and even in the refineries and power plants but when you get down to refinery's on the coast you will start seeing some non-American work force. Usually not even able to communicate with foreman's without a Interpreter. Now if you're talking about painters, insulators, machine operators and roustabouts are almost all from some country south of our border legally here on either asylum or some visa.
