This has more to do with you apparently not following Trump's rallies nor reading his immigration plan. His immigration plan wasn't published "a few months later" saying these things (as well as an American workers first policy). It said them from the beginning, and Trump, from the beginning, has stated in tons of rallies, not just over the summer, that he wants high end immigrants who attend our universities to not be thrown out. You might claim that these two consistent positions contradict each other, but, not really.
It's about picking and choosing what kind of immigrants we want, and yet still prioritizing American workers. It is not a war to kick out even the legal immigrants.
From the 60s on, foreign nationals at universities were running around like ants, mostly in accounting, engineering and the hard sciences.
Now, they’ve run off with our nuclear crown jewels, courtesy of Clinton and 0bama. And, the big research $$ has gone to Asia, with quiet pockets of $$ remaining here.
I am absolutely terrified for people coming of age now. Frankly, had I any children that age, were they not going to drive toward being in DevGru if at all possible, I’d tell them to learn Mandarin and go to Hong Kong or someplace the other side of Bora Bora. The people I hear about making really good legitimate $$ in the world now are right next to the commodity-which is often a very dangerous place to be.
