It's fairly embarrassing that I've never linked to this chart, which does its best to explain the legal immigration maze.
Something to remember when angry people in border states complain that people should come here legally. I'm not advocating for illegal immigration, of course - just pointing out that the current clusterfuck of a process, which results in a few tens of thousands of people becoming permanent residents every year, and a couple other tens of thousands being eligible to work here, is beyond broken.
PS. Hat tip to AF for reminding me of this a few weeks ago.
