May I presume that you were born in Germany because one of you parents were stationed there as either an active duty military service member or as working for a US contractor at the time of your birth?
If so, then your statement is ridiculous. Why would any US service member or diplomate who is married and has a spouse living with them while on assignment, take that assignment if that might mean that their child wouldn't be a full natural born citizen if born in a foreign country while on assignment.
If you were born in a German hospital, then of course you would have a German issued certificate of a "live birth". That does not convey citizenship however, and if you parents registered your birth with the US Consulate, which I imagine they did unless they were idiots, then your birth and "natural born" citizenship is no different of that of one who was born on US "soil".
My statement is NOT ridiculous. Yes, my father was stationed in Germany. I was born in a German hospital. I do not have a born in the USA birth certificate. My parents are the only people that could give me natural born citizenship. They did NOT.
That's incorrect. Birth-abroad is remarkably different from being born on US soil. There are hundreds of cases on this subject, in complete agreement.
See Thomas v. Lynch - 5th Circuit - August 7, 2015 - 14-60297, which holds US military bases abroad are not US soil.
Thomas, born at a US military base in Germany, fathered by a US citizen and serviceman, was NOT a citizen of the US.
