The morale of the story: don't sign incomplete forms.

As for the GC case, I believe he can still make it work if he makes enough noise to get noticed by governor-level politicians. As a backup plan, he can immigrate to Canada: about the same culture, with only a few minor differences.

Whether he really needs to make it work is another question. As I get older, from time to time I entertain the idea of eventually retiring to a cheaper country, as the likely alternative is be robbed by the cruel healthcare system in my 50s or 60s.

I agree that America is the best place for ambitious smart single dudes without health problems, but as those dudes get older, they quickly realize that their exceptionally well paying job doesn't buy them a house near their workplace (especially in SF!), that all the family related things are ludicrously expensive and that any moderately severe health issues will empty their nice 500k savings accounts real quick.

How can you avoid signing ‘an incomplete form’ when so much problems can be caused by marking a checkbox? How can you avoid someone doing that after the fact?

I think he should have checked the fourth box. [IANAIL]

If someone else completed this, the problem is that to check the fourth box you must add some "Alien or Admission number" that the other person didn't know. It's easier to check the first box that doesn't ask more questions.

That's a radio group, not a set of checkboxes. Exactly one must be selected--the form isn't valid with none marked.
