being born on foreign soil of only one US citizen parent....
Yes, he is the son of a US citizen. Case closed.
he is a US citizen... but he was also a canadian citizen until recently.
OBVIOUSLY, he’s not a natural born citizen
“Yes, he is the son of a US citizen. Case closed.”
Maybe he is and maybe he is not lawfully a U.S. citizen. You can help everyone determine whether or not the grant of U.S. citizenship was subsequent to a lawful or an unlawful claim of the child’s birth to a wed or unwed U.S. citizen mother resident in the United States longer than one year prior to the son’s birth.
Note, however, acquiring U.S. citizenship by grant of citizenship in accordance with U.S. statutory law regarding a jus sanguinis relationship with a U.S. citizen mother is the application of unnatural law to produce unnatural citizenship that is the exact opposite of and excludes any possibility of natural law and natural born citizenship.
