> Cancelling visas or deporting them will not get American workers their jobs back

So I think what some in this thread are saying is it quite literally 'will' bring American workers the literal jobs that the H1Bs aren't doing anymore.

> but a large amount of them work hard to come here and setup roots

So two things can definitely be true here. They can be hardworking and well-intentioned, and they can still be used as a wedge between American workers and slightly better jobs

There is no guarantee that any American will be hired to fill any job vacated by a former H-1(b) holder. The firm could contract or fail against foreign competitors.
