Obama is a natural born citizen, having been granted citizenship upon birth when he was born on American soil.

BO's/BS's father was not an American citizen and therefore could not transfer his citizenship to BO/BS. The law required a parent to be physically present in the U.S. at least 10 years, five of those years after the age of fourteen. She needed to be at least 19 years of age. She was only 18 years old and therefore was too young to transfer her citizenship to BO/BS.

There still is no documentation proving BO/BS was born on American soil.

The age of his mother would only matter if he were born in another country. Since he was born in the United States, he didn't need someone to "transfer his citizenship." According to the 14th Amendment, he was a citizen at birth.
