Disney performed a slight-of-hand to eliminate a chunk of their IT to then outsource to a firm of H1-Bs. This would be illegal if Disney did this, itself.
It should be illegal to do it this way, as well.
That's the other huge hole in our trade and immigration policies- the ability of US corporations to outsource US jobs. It's not clear what can be done about that. Free trade has already screwed the pooch on that count. I think Obama is trying to tax US corporations on overseas profits. That might help repatriate some US jobs. It's truly a race to the bottom.
