Quote from CaptainObvious:
...The phrase "subject to the jurisdiction thereof" was intended to exclude American-born persons from automatic citizenship whose allegiance to the United States was not complete. With illegal aliens who are unlawfully in the United States, their native country has a claim of allegiance on the child. Thus, the completeness of their allegiance to the United States is impaired, which therefore precludes automatic citizenship.
Therefore the correct interpretation of the 14th Amendment is that an illegal alien mother is subject to the jurisdiction of her native country, as is her baby.
Some history:
In 1889, the Wong Kim Ark Supreme Court case10,11 once again, in a ruling based strictly on the 14th Amendment, concluded that the status of the parents was crucial in determining the citizenship of the child. The current misinterpretation of the 14th Amendment is based in part upon the presumption that the Wong Kim Ark ruling encompassed illegal aliens. In fact, it did not address the children of illegal aliens and non-immigrant aliens, but rather determined an allegiance for legal immigrant parents based on the meaning of the word domicil(e). Since it is inconceivable that illegal alien parents could have a legal domicile in the United States, the ruling clearly did not extend birthright citizenship to children of illegal alien parents. Indeed, the ruling strengthened the original intent of the 14th Amendment.
The original intent of the 14th Amendment was clearly not to facilitate illegal aliens defying U.S. law and obtaining citizenship for their offspring, nor obtaining benefits at taxpayer expense.
You don't need to be a legal scholar or constitutional wizard to figure this out, but you do need to be honest enough to put the needs of the country first rather than your political agenda...
