And this couple did exactly what your son did. What would you do if ICE came to your daughter-in-law's door seeking to deport her after everything you knew they did for her to be here legally? You know they filed the paperwork and paid fees. They may have had a lawyer assist them, too. That's just what happened with this couple and that is not a violation of the law? Based on your own arguements, then, you beleive that someone is guilty of something they know they didn't do because someone else, either their representative or the government, screwed up the paperwork. My advice, be careful comparing this situation with that of your family. Your family could very easily have been in the same situation and I'd expect you to call your son and daughter-in-law law breakers, even though it wasn't anything they did.
Wrong, my son and his wife have never had this problem. I suppose there are ways to keep from violating law(s) where one doesn't get the 'visit'. LOL
