“under the jurisdiction of” means more than an illegal alien in heavy labor just being pushed or rolling across the southern border in order to drop an anchor baby...
"Under the jurisdiction" means having to pay your parking tickets. Foreign diplomats in the US do not have to pay their parking tickets. They enjoy diplomatic immunity. They are not subject to US jurisiction, and, hence, any children they may have while residing the US are not anchor babies. Other foreigners in the US are subject to US jurisdiction, which is why, under the 14th Amendment, children born here to them are anchor babies.
