I am sure there are some legitimate uses of the H1B visa.
The key problem is that it is structured to serve employers not people seeking to immigrate to work here, and to compete head to head with people already here, at the average wages their job peers here can command even when their are a lot of job vacancies looking for workers.
No, a big junk of the H1B is to serve employers just so they can bring in the “special” foreign people they have hand picked ahead of time. And far, far too often the excuse that they are people who will do work “no one else” could be found to do is just that, an un-investigated excuse. Then the foreigner is often at the mercy of the H1b employer - they can keep working for that employer or go home, because they cannot leave to work for some other employer here, unless (a) granted the O.K. by their H1b employer and (b) the new employer is able to help them get a work visa. That usually only happens after years of being stuck with the H1b employer, and often at wages below what they could get on the open market here.
How about ditch the whole damn program, really who cares, it is not the governments responsibility to help corporations hire foreigners.
