Anyone born on American soil is instantly a citizen per the 14th Amendment

That is not the complete statement of the 14th amendment. There are exceptions.

[Taipei]

The only exceptions were Native Americans, hence the line ‘subject to the jurisdiction therof.’ Since the Indian Citizenship Act of 1924 there are no exceptions.

The text:

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.
