Hi EagleMama a few months back I did see on CSPAN a rep from the Bush administration who stated the program would be open to every sector of the economy. And just the idea of a job opening meant the employer needed a willing employee, which translates into filling that job with a foreigner if necessary.
So my impression was no numerical limit would be placed on the number of guest workers who could be brought in. At least H1-b does a have cap, though that's no comfort to the thousands of tech workers who have been displaced.
That's pretty much what I was afraid of. Thanks for the information.
