Hey Robert - My Question: What do you think would happen to tech in America if H1b's were done away with and all foreign workers had to leave?
Related question, would Donald Trump actually be able to do away with the H1B as he suggested he would a couple of months ago?
H1B abuse typically involves posting an absurdly specific or unappealing set of requirements in a job ad tailored to the person you're trying to get a visa for. If any qualified US person actually does apply, they are rejected for whatever spurious reason. The employer can then claim "no suitable candidate can be found" and get a visa for their immigrant.
I'm not sure how this can be prevented.
