This isn't what FC is saying.
Again, the citizenship language of the 14A is a two-parter.
One must not only be under US jurisdiction (as a Mexican arrested in the US is, and like a US citizen arrested in Mexico would be under Turkish jurisdiction) - one must also be born or naturalized in the US as well.
Being under US jurisdiction is only part of what is required for citizenship. It does not in and of itself constitute citizenship.
Read post #89 and check out the links, just possibly you might learn something, although I am not going to hold my breath.
Thanks.
