Except for clarification of 14th Amendment:
“All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States”
When an illegal gives birth in the US and then leaves, is their newborn subject to the jurisdiction of the US and for that matter if their parents stay and invite all their relatives to join them, are they then subject to the jurisdiction of the US? I don’t believe the founders ever intended that Amendment to be used for anything except give the freed salves the right to have the same freedoms as other natural born citizens enjoy.
With that, I would also forbid “dual citizenship” — it’s an oxymoron and goes to the heart of true loyalty whether Natural born or Naturalized.
