Illegal Aliens can't have a legal domicile in the US. Only aliens who have green cards can have a legal domicile in the US. Illegal Aliens are temporary residents only. They owe their allegiance to the country that they are citizens of. Illegal Aliens are in the same situation as Elk's parents and like Elk their children are not US citizens.The law does not differentiate between legal and illegal. If they are domiciled in the US, they have rights.
