There is a branch of the tourism industry that is designed to obtain US citizenship for the babies of well to do foreigners, typically Asian. "Delivery vacation." The child is taken back to the home country (say, Japan) and is raised there.
Most lawyers will tell you that this child qualifies for the presidency, as being a natural born US citizen. They'll point to the Wong Kim ark case, and the 14th amendment. AND, they'll do all of that with a straight face - IOW, they actually believe the conclusion is the correct read of the case law.
Thanx you guys. Since I made that posting I did some reading and discovered we have this little marvel called “jus soli” that makes this whole anchor baby thing work.
I always wondered what was the legal basis for this concept, now I know more.
