It was a 14th Amendment case and the decision of the court was that there were only 2 types of citizenship, by birth(natural born) or by naturalization because under both forms, the person only has but one allegiance to the US, one at birth, the other at naturalization upon renouncing allegiance to a former nation.
There are no sub-class of citizens according to the Constitution, one is either naturalized by an act of congress & renunciation of foreign allegiance or they are born owing a single & exclusive allegiance to the US.

But alas, they will never see it because their egos & legal education have turned an ant hill into mountain by adopting the lies of the adversary aka “jus soli” citizenship regardless of the nationality of the father.
