My point is that even if H-1B were eliminated and all the people that hold them today returned to their home countries, employers' response is less likely to be "we need to hire and train more Americans, asap" but more like "let's expand our overseas operations, so we can get work done without paying Americans".

In other words eliminating immigration like this is only half the solution of you don't also have a way to stop offshoring.
