How to make my facebook profile visible to everyone in the world?

idk if you can do that

maybe try changing the privacy options

http://www.facebook.com/home.php#/privacy/?view=profile
in profile select everyone, maybe that works

all you have to do is click settings beside the search engine to the left of log out scroll down until u c privacy click it then click profile then go straight down the line clicking the scroll bar that says everyone then every time someone goes on facebook your profile will be where the ads r

good luck

Just go to privacy settings and set everything to everyone. So when you save the settings your profile will be visible to everyone.
