An article from CNET tells of a move to reduce or ban the use of the L-1 visa, which many technology firms have used to transfer in "temporary" workers from related firms outside of the US.

This differs somewhat from the H-1B visa for highly skilled workers that requires much more paperwork and also requires that the employees be paid the going wage for their equivalent experience, thus making foreign workers and nationals equivalent in terms of cost (actually, giving the nationals a slight advantage because of the paperwork).
