How can a child who did not sneak in be considered ‘under the jurisdiction of their homeland’, a country they have never set foot in?

The law doesn't say "under" it says "subject," which, given that I posted a link to an 1856 law dictionary above AND that definition is in the article you clearly didn't read, renders your "question" baiting and misdirection on a foundation of ignorance.

Apparently it’s also point well taken. The child knows no other country than the United States. Her home country is the US, the country she was born in.
