One of the most insane arguments is the idea that your parents status matters. “Subject to the jurisdiction thereof” applies to the person born. It does not say your parents must be subject to the jurisdiction. Even though they would be subject to it, if they were not, the child still could be. Which is the very reason that the US makes a tax obligation on everyone born in the US, on their lifetime worldwide income. So the US has, for decades, been arguing they do have birthright jurisdiction to people born in the US (including those born to illegal immigrants) by nature of levying a tax on income those people earn, even if they return to their parents home country.(Adam Cochran (adamscochran.eth))
