I am a naturalized citizen. On June 12 of this year it will be 39 years that I made my Citizenship in Junction City, KS. Both our son who was born in Germany in 1963 and daughter who was born also in Germany in 1970 in the same US Army hospital when my husband was station in Germany. My husband registered their birth with the American Consulate in Munich, Germany, when they were 6 weeks old and they were issued an American Birth Certificate.
They would have not gotten an American Birth certificate had the American Consulate considered ineligible due to that I was still a German National.
Citizens, yes, natural born citizens, no.
