Face tattoos and surgery require a new passport
No, a Brooklyn-style beard or cutting or dying your hair aren't big enough changes to require a new passport. But if you go all Mike Tyson and get facial ink, lose a ton of weigh like Jared from Subway, or undergo facial surgery, you'll probably have to get a new passport.
You can't wear a uniform in your passport photo
Just like a lot of bars, passports won't let you wear a uniform -- not even a throwback Natrone Means jersey -- in your photo. Unless it's for religious purposes and you wear it every day. Which, more people should bow at the altar of the 1994 All Pro San Diego Charger. Oh, and hats and headdresses are banned, too, even if you're Pharrell.
Glasses are totally cool, though
First time anyone's probably ever said that. As long as they're prescription specs you wear daily and there's no reflection in your photo. You can even wear tinted sunglasses if you have a medical prescription to back it up. Maybe even rec specs, like Kurt Rambis.
