> You're aware that there will continue to be immigration without the h1b visa, right? That's just a common way big corporations use to import cheap labor, at least that's what I looked like to me - because id be fully at the mercy of the company I'd be unable to really negotiate my contracts etc

I believe the parent is referring to the knock-on effects of all the other immigration enforcement actions.

I largely agree with you about h1b specifically but this move doesn't exist in isolation. It's increasingly clear that the US is determined to make life hard on immigrants in general (or at least harder) and this is just another data point.
