Well, I went and applied today, in case anyone's interested. It cost me $112 all together. $45 to the post office for pictures & processing, $67 to the US Dept of State. I am nervous, though, because they kept my original birth certificate. When I asked for it back, they said, "Oh, no. That goes with your application." So, I'm a little nervous, but crossing my fingers. The guy at the post office said within one week I should be able to check the status. Keeping my fingers crossed!
