I see roofer's, cement contractors, carpenters, bakers, engineers, real estate sales people, nurses, and more being manned by temps that can only stay so many months and then have to return to whatever country they came from....I'd like to know just who decided these jobs were jobs that no american wanted? I am not against migrant workers but the temporary work visa vs the green card verus permanent alien is being fudged...A Japaneese family was here for three years that's mildly ok, but the 9 monthers something is wrong with this. Students count on seasonal labor to get money for classes and this just negates that they're even a possible answer.
