According to the laws on the books at the time of Obama's birth, a woman had to have lived in the US for a period of no less than 10 years, 5 of which had to be after the age of 14 in order to convey simple US citizenship to her offspring.
Stanley Ann Dunham was 18 at the time of Barack Obama Jr.'s birth, so was not legally capable of conveying even simple US citizenship to him, let alone Natural Born Citizen status.
I don't have the citation handy, but it's been posted here on FR hundreds of times. Perhaps someone else will post the exact citation and text of that law for you.
Yeah, hopefully someone will post the citation. I can find this referenced on this site and by googling, but no one ever mentions the source of the law - frustrating. I am also not finding it on find law - but that is keyword driven, so not so surprising.
Basically - though - If I understand you - no one whose parents were under the age of 19 at the time of conception could become citizens. Is that correct?
I guess ask and I shall receive. 7 Fam 1130 - just downloaded it from the State Department.
It only applies if Obama was not really born in Hawaii, but somewhere overseas.
Many thanks to Dj Mac Wow for the cite in the other, current, ongoing thread.
