When we arrived in Portland, Sarah became an American. She already has German citizenship. We got pulled aside to go to the secondary screening room with all the Arab men under the age of 40. Poor men...but I can understand the need to double check these poor guys. Sarah now has an American citizen visa stamped into her Chinese passport. I will return with her to Germany using her German passport. It was a very exciting moment to me when Sarah became a citizen, but the security officers didn't even say congratulations. I guess that was sort of a let down.
