The child born of alien parents in the United States is held to be a citizen thereof, and to be subject to duties with regard to this country which do not attach to the father. The same principle on which such children are held by us to be citizens of the United States, and to be subject to duties to this country, applies to the children of American fathers born without the jurisdiction of the United States, and entitles the country within whose jurisdiction they are born to claim them as citizen and to subject them to duties to it. Such children are born to a double character: the citizenship of the father is that of the child so far as the laws of the country of which the father is a citizen are concerned, and within the jurisdiction of that country; but the child, from the circumstances of his birth, may acquire rights and owes another fealty besides that which attaches to the father.
