Would Bruce Caitlyn Jenner be called a woman in her Passport?Gets Praise from Obama

Bruce Jenner now Caitlyn Jenner.

Caitlyn Bruce Jenner gets 1m Twitter Followers in 4hrs & Gets Praise from Obama.

Caitlyn Bruce Jenner has become the fastest person to amass a twitter followership,after she gained 1 million fans in less than 4 hours! Caitlyn Jenner took to twitter to thank the fans and comment that at 65 years of age she is finally leaving her life the way she wants to!
Caitlyn Jenner also got a mention from the President of America,Barack Obama,who commended her for sharing her story.I am not sure this is President Obama's place though.Hasn't he got more problems to worry about than commenting on show biz stories online? Just my thought...

65-year-old reality star,Bruce Caitlyn Jenner, made her introduction to the social network on the same day she revealed her female form to the world with her Vanity Fair cover.

Friends, fans and loved ones spoke out on Monday about Caitlyn's unveiling on the cover of Vanity Fair. Another curious thing on my mind,can Caitlyn be referred to as a woman without having the full operation to get rid of her male bits? Does one become a woman just
by proclaiming it? Or is there a certain requirement by law? Would Bruce or Caitlyn be called a woman in her passport for instance? Or will that take effect when she has the operation? I am just baffled and somewhat confused here.
