And how is it punishing the child for the parents transgressions? Is it "punishment" to withhold citizenship? How? They have the citizenship of thier parents country and can go back there at any time so its not like they are countryless (if thats even a word). With your kind of arguement then the whole world should just be deemed citizens of the US. Sorry but we do not have the resources or space to house and take care of the entire world.
