It's not that they have "immunity", it's about whether the US Government has jurisdiction over them, meaning they can conscript them in time of war, collect taxes and so on, and that there isn't another foreign power that can do or already does this. Howard, who introduced the Amendment, said this[1]: >This amendment which I have offered is simply declaratory of what I regard as the law of the land already, that every person born within the limits of the United States, and subject to their jurisdiction, is by virtue of natural law and national law a citizen of the United States. This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers accredited to the Government of the United States, but will include every other class of persons. It settles the great question of citizenship and removes all doubt as to what persons are or are not citizens of the United States. >Now, all this amendment provides is, that all persons born in the United States and not subject to some foreign Power—for that, no doubt, is the meaning of the committee who have brought the matter before us—shall be considered as citizens of the United States ... If there are to be citizens of the United States entitled everywhere to the character of citizens of the United States, there should be some certain definition of what citizenship is, what has created the character of citizen as between himself and the United States, and the amendment says citizenship may depend upon birth, and I know of no better way to give rise to citizenship than the fact of birth within the territory of the United States, born of parents who at the time were subject to the authority of the United States. Doubly funny that he added a line in that speech where he thinks all ambiguity is gone.
