Sure!
I could marry(heck you dont even have to marry) a gal in timbuktu and have child with her and have him be a citizen of Tx
Yes, you could, but Stanley Ann could not, at the time BHO was alleged to have been born. You are over 15, and have ( I guess) resided in the US for more than 5 yrs (the law has changed since BHO was born, then it was 10 years and over 18).
Have at it. Although I think I'd pick someplace like Bali or even the Ukraine or Georgia over Timbuktu, which is in Mali, near Africa's Ivory Coast. But to each his own preferances.
