As an aspiring immigrant, I feel this is great. Instead of a situation where immigration to US sort of works, sort of doesnt, is a hassle, but not really a bad one, a lot of companies were still keeping major offices in US.

Now that Americans have made up their mind that they dont want immigrants, companies will spend more money on opening engineering centers in immigration friendly countries (Canada\west Europe\Australia(maybe),etc) which from a personal perspective are great countries for me to immigrate to. And this time I might would be able to catch the first wave of immigrants (who get to convert to citizens) if there is a genuine boom in jobs in such countries (unlike US where its near impossible for an EB2 immigrant to get citizenship if moving today)
