It's also awful on the permanent residency front. I lived in the US for almost a decade now, graduated from top 5 school, currently a graduate student in n.1 US school in my field, while working at a top firm full-time. Green card application got put on permanent hold for a technicality (same thing for hundreds of my fellow international coworkers), and so it will likely take me anywhere between another 5-10 years to get one. And I'm fully documented up to my ears, I imagine there's even more horseshit for illegals.

No prospect of ever leaving my employer unless I'm willing to go back to the other side of the pond...
