It's funny going through this process a third time around. You'd think I would make no mistakes at all. That I would get everything right. Not this time.
We show up at the USCIS office downtown, park the car, and proceed into the building and through security. It's like airport security, only you get to keep your shoes on, but they do scan whatever you are bringing in with you. And here am I, walking in like I am totally with it, and the security guard calls me over. "Ma'am, you've got something in your purse that we cannot allow in the building. It looks like a pair of scissors. Do not open your purse in front of me. Just take the purse out of the building and dispose of the scissors."
I felt like a total idiot, like I had just fallen off the turnip truck. Poor Jerry! He ran my purse outside, took the scissors out, tossed them in our car, and ran back in. We made it through ok after that!
The fingerprinting was a piece of cake after that.
