Already happened. My company has sent notice to us that international hired employees are preferentially located to Canada and other sites instead of US, since it is difficult to get a visa here.

People are selfish, so I don't blame them for want to close the door and keep the outsiders outside so they can have a bigger share of the pie.

But don't expect to see that happen either, companies nowadays are much more powerful than individuals and they are very nimble, they will go to places where cost is lower, this won't change a bit, it is in their blood.

So to immigrants coming to US, don't really put much hope in spending decades waiting to get permit to not in living in fear of throwing out. Doesn't worth it. And the resentment towards immigrants is worsening everyday, unless you happen to have certain skin tone. So earn your bucks, and save more, when the time comes take your life and skill elsewhere, life is too short to just wait in vain and hope for the best, act swiftly and you will be happier ;)
