Hire and fire them here. But the H1-B visa program was predicated on the notion that there was a shortage of tech workers in the mid-to-late 1990s. That is no longer the case, and it should be ended.
BTW, most of the H1-B holders I have worked with weren't worth much, but they worked for peanuts, so they got hired.
The re-work is killing us here... but yep, they're cheap and exec. mgt sees the payroll savings but not the re-work figures. Waddya say when the OT goes thru the roof to fix stuff?
