I appreciate the way you phrased that, "what the legal system says" rather than "the laws," since it's important to keep in mind a lot of what we're talking about is mercurial executive branch policy rather than statutory law. (which is why US immigration has been such a shitshow for such a long time)

On the other hand, you're apparently ignorant of what's actually happening, and it's making you write stupid things. The Trump administration's policy changes when he took office immediately made a lot of people, not my choice of words, "illegal" immigrants instead of "legal" immigrants. Maybe you support that, that's your business, but to claim those people were not "trying to emigrate legally" because the new administration changed the rules is simply dishonest.
