‘waits in line’ is different than a person who pushes their way to the front.
Sorry to bust your bubble: Consistently for my 81 years most immigrants come here “illegally” and then apply for papers to stay here. That is because the immigration system is broken and nobody can agree on how to fix it. And many refuse to admit that it is broken.
Tourists come to the US..start work at a job ... and then apply for H1b.
Illegals come here, marry a legal, or have birthright children and then use that as reasons to apply to be here legally.
Immigrants come to Canada and obtain Canadian Citizenship. Then they go to work in the US. Canada is happy to take the middle man fee, knowing full well many of the immigrants they accept will live and work in the US and not in Canada.
Satyam scams are numerous. Multiple people working on one H1b. Non-working spouse sharing a H1b with a “cousin” who is working.
Many games to play. The problem is that nobody really wants to face all the different ways. If one way is made more difficult it just puts pressure on the less difficult way to expand.
The bad that has happened can be undone just as it was done.
Did you notice how quickly Trump closed the border? Less than 6 months.
