What you have not shown is the section that says they can be denied citizenship when they present evidence that they meet the statuatory criteria. So, “acquired” means taken up at a point in time that which is already acknowledged in the terms of citizenship by birth. I’m not at my normal computer, so I can’t find it at the moment, but even in the FAM that idea is preserved down a few paragraphs from the section dealing with blood or geography as the basis of one’s citizenship.
The most recent law (newer 1401 replacement) governs even the FAMs, and it says something along the order of the following shall be citizens at birth:
a. those born in the US to citizen parents.
and somewhere down the list it has those born overseas to US parents. I don’t recall the sub-paragraph letter or number. But, if one is a “statuatory citizenship”, then all in that same major paragraph are also statuatory citizens.
And, indeed, we are required even to document that we have been born in the USA....birth certificates, baptismal records, etc., are legal means of doing so.
Ummm, you may want to rephrase that. What we are sometimes asked to prove is that we are legally present, and/or that we are citizens. Your argument depends on birth location being an irrelevant factor, if one parent is a citizen.
The statute, which you elevate above the constitution, also says anchor babies born of alien parents are citizens. Not relevant at the moment, but may be for a future candidate.
