By the way, the "oh boy, this looks like a lot of trouble, but it'll be much easier if you sign this form", and there goes your greencard, has been going on for a long time.
A friend of a friend traveled to the US with her newly born baby to see the grandparents, and was told at immigration that she hadn't been in the country for a while, and the greencard might have to be revoked, and she could either fly back or get a lawyer and fight it (while in no-man's-land) or sign a form, forfeit the greencard, but enter for now (as a tourist). This was last decade, and I might have the details wrong, but basically she signed, as the alternatives (with baby and all) were even less appealing, and the greencard was gone.
(Note that if she had been rich, at that point the exit tax would have kicked in, too.... fun fun fun)
