My neighbors’ son was born in Turkey, while the father was deployed there. Both parents are birth citizens of the US. When the son turned 18, he had to go to Turkey to renounce his dual Turkish citizenship, or face Turkish military service. The parents assume he’s ineligible for U.S. Pres.
They’re correct.
He is a citizen though, if all the paperwork was done properly shortly after his birth, because he derives his U.S. citizenship from his parents (jus sanguinis - “by the blood”).
I suspect the purpose of the natural born citizen requiement - born in the U.S.A. of citizen parents ( jus solis + jus sanguinis ) - was to prevent someone who wasn’t born here or who was reared primarily out of the country, from ever becoming Commander-in-Chief.
BHO2 is a great example of why the founders thought that way!
The good news is your neighbor’s sone is eligible to stand for all other elective office, save the Presidency.
