SO you are saying that it's ok for an American citizen to be forced to relocate because their parents couldn't be given a permanent visa after 17 years? Sure my daughter might be able to thrive but why?
I am not saying any of this, I am just responding to your point which I understood as "I have 10 yo daughter who has not seen the rest of the world, thus I cannot relocate".
That’s a family choice for her to leave the US or not. That there might be one obvious dominant choice does not change the fact that it’s a choice. That choice you face today is influenced by a choice the parents made a couple decades ago. All still choices.
My kids might be forced to move if I got a job in another city or or if one of our parents fell ill if my wife and I divorced or any other number of reasons, including simply deciding to move someplace else.
It’s a sucky situation that you want and can’t get a green card. I think you share that same situation with 10s or 100s of thousands of others.
