This is unlikely to be passed. It has to be approved by Congress, which is controlled by the opposing party. Even if the Republicans win the next election it is unlikely this specific bill will be passed.
As far as the specifics for this, all the article says is highly educated people would be given preference. I would assume this would mean a person with a master's degree would be given more preference than one with a bachelor's, but not as much as one with a doctorate. I am sure the area study would play a large role in this as well. Job offers are always helpful, as is the ability to speak English
Congress isn't controlled by the opposing party, it is split. Regardless, there is value in the proposal because, agree or disagree, it is actual policy you can't weigh in on by voting in the next election, not just the usual vitriol.
You're right, the House of Representatives is controlled by the opposing party, I always wrongly consider this "Congress" because it is full of what we call Congressmen and women, whereas the other house of Congress is filled with Senators, which I supposed are also Congressmen and women, but I never hear them called that.
Considering there's been a high incidence of low quality "degrees" from other countries I would hope so
Same issue in the US, especially with the rise of predatory, unaccredited colleges.
