We’re going to give Flickr user Cazimiro a pass on the poor quality cameraphone pick, to say: Congrats! Cazimiro, who lives in Arlington, took the oath yesterday to become a naturalized citizen of the United States. Especially at a time so close to a presidential election that’s fired up such a huge percentage of Americans, it’s exciting to see even more people work so hard to become part of this democracy. A little sappy? Perhaps, but I bet Cazimiro is one happy man today. (Unfortunately, he was naturalized a few days too late to vote in this election — but it certainly isn’t too late to participate in other ways.) In his set of photos, he challenges us to the ol’ civics test required of all immigrants. Can you remember all the answers?
