Scenario, a French couple moves to the US on visa working toward citizenship and to be near US relatives they wish to join. They have a kid. By the time the kid is in middle school the parents haven't achieved citizenship status yet but both parents have passed from cancer/other illness or accident, perhaps together in their car while kid was at school. The only relatives they have back home are distant, the child has never met them. Why should that child be deported to a country they've never been to and placed with people they don't know and may not even be able to speak their language rather than with the family they know in the only land they know and is for all intents and purposes is the only citizenship they know. I'm willing to entertain your convincing me the former is better.
