Ok, there is a piece of the Selective Service Card that I have not seen discussed yet. Barack Obama's 18th birthday was August 4, 1979, not 1980. So why is there a July 29, 80 stamp on his card, when we was approaching his 19th birthday?
If you are a man ages 18 through 25 and living in the U.S., then you must register with Selective Service. It’s the law. According to law, a man must register with Selective Service within 30 days of his 18th birthday.
