Trump's pandering to his audience is getting out of control. At this rate, the next time he gives a speech to a Muslim crowd he will end by declaring Jihad on the West.
Overall, Trump's proposal is not ideal, but it's a big improvement over what we have now.
First of all, almost always, foreigners pay out of pocket for our overpriced university degrees. They do not get Federal loans 99% of the time, as far as I am aware. This means that the amount of people who will be able to pay for a 4-year degree, find a job, and stay, will be less damaging than the H1-B program, since H1-Bs do not need to have graduated from the USA - they can go some dirt poor college with no loans, then come in and take an American job.
Additionally, America will be pulling in children of rich foreigners, since it's not cheap to pay for a university here out of pocket. As such, these college immigrants won't be gang-raping kids and causing mass crime like the open borders illegals do because they are from well-to-do families. On top of this, illegal immigrants vote in huge numbers, because voting laws aren't enforced, which is why Demonrats love them so much.
Currently, America has close to 750K foreign students each year:

Nearly all of these students pay out of pocket, and are probably 60-80% women. Furthermore, at least 1/3 to 1/2 are from Europe if I had to guess. So it's not like we're substantially changing demographics. BUT, if we consider 1/4 of these students to graduate each year, it means we'll be adding around 250K greencards per year. It will create more competition in the American job market for high paying jobs.
Additionally, since most college graduates are women, by giving college degree holders a green card we will be importing huge numbers of young, well-off, educated women into the USA. By comparison, H1-B are mostly men from poor black and brown countries. This is an improvement.
2-year undergraduate degrees for a green card seems like a joke, wide open for abuse, and that should be thrown out. But in for 4-year degrees, and graduate degrees, that's a big improvement over the H1-B system which takes low-skilled slaves from around the world at random.
If Trump's immigration policy were to be put into place fully, where zero illegals can come, but college degree holders are given greencards,
we would still see a net reduction in immigration to America by over 95%. However, it is unclear if Trump would make any changes to the
normal greencard process which is open to all kinds of abuse, but I assume Trump would want changes since Stephen Miller is Trump's immigration Czar.
That said, despite how Trump's immigration policy would just import tons of college educated women at the expense of the rest of the world (which is a positive for American men, no matter how you slice it), we all know that Democrats will fight this tooth and nail in Congress because there is no way they will relinquish the massive immigration hordes pouring over the border right now.
Trump is merely offering a compromise on the immigration issue to win over moderate voters, and conservatives who reject this because they cannot become dictators and get everything they want are dooming themselves and their country by rejecting common sense. I would much rather have hordes of hot young babes immigrating to American than barbarian rapeugees by the millions.
