What do you know about 120 volt wiring? I imagine that if you have the right to work in the US, you would then have to pass the licensing exam, and where there are strong unions, possibly get into a union. I don't think we had an electrician shortage even during the construction boom, and now that that is over, I can't imagine you would have much luck finding work.

Consider Australia. They have been screaming for people in the trades.
