Too bad that being divorced and now outside the immigration loop I am double-screwed by biased family courts and immigration laws. Makes me almost wish I could ask for a GC if I sign up to go help hunt down illegals. I am being sarcastic and provocative.
I don’t know if this will help you or not, but the U.S. military fast tracks foreign born soldiers and Marines for U.S. citizenship. If this information (available on many gov’t and mil sites) does not help you, perhaps you could get the word out. I am sorry for the situation with your daughter, and will tell you that immigration has been a mess here for years, largely due to the endless red tape. My cousin married a lovely Canadian girl and and it was over two years before she could legally join him here. I never saw anything so stupid and cruel and unfair in my life. They did the right thing and were punished.
On the bright side, it turned both of them into hardcore conservatives! Good luck to you.
