However for the following to be true, there needs to be one other part of the formula - JURISDICTION!
The mexican anchor baby, still would not have JURISDICTION, as it’s parents are under Mexican law.
A most astute insight, syc1959!
The Fourteenth Amendment says:
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.... [bold itals added: There are TWO criteria to be satisfied here, as you so astutely note syc1959.]Question: How can a minor tyke born on American soil to non-U.S.-citizen parents be "under the jurisdiction of the United States?" As a minor, the child is under the (natural law) jurisdiction of its parents — who owe their principal allegiance to a foreign nation/state and are therefore not themselves subject to the jurisdiction of the United States.
It seems the Fourteenth Amendment, with its jus solis doctrine, has vastly complicated the citizenship issue! JMHO, FWIW.
Thank you so much for your great observation, syc1959!
