That still doesn’t answer the question of why we’d need to change the laws to allow them to work. So what if they’ve earned a college degree? They can now be more gainfully employed back in their homeland.
(and then try their hand at legally immigrating)
Why spend our money then to educate people who aren’t going to be able to be productive to the country?
The way I’m understanding this is that they must be on a path to citizenship so that when they were finished their education they would also have citizenship, thus allowing for them to be legally employed.
