Interview was yesterday in Detroit. Arrived about an hour early, the waiting room was filled with kids and cell phones (both of which we hadn't brought along). Got called in about 10 minutes before the scheduled time. Had a very strict officer who gave lots of "orders" step forward, sit down, take a piece of paper, etc. She was nice but not really friendly and very much an officer. Before even saying hello jumped into the reading and writing portion of the exam. and then straight onto the civics questions. Reading was "who is on the dollar bill" writing was Washington is on the dollar bill. Questions included when the constitution was written, 1st president, where is the statue of liberty capital of the US, number of senators, and boarder of canada and mexico. Then lots of unexpected "have you ever" questions. Asked if ever drinks alcohol, how often is drunk, and other questions that we are not sure where they came from or why. No history of anything likely. Then asked name of children and birth-dates. If spouse is US citizen, birth date, spouse's employment status, employer and profession. How many trips out of the US in the last 5 years. When was the last. Asked if filed taxes, if owes anything, when filed last taxes (a month after our application was sent). And asked height of applicant. Asked several other questions and after 30 minutes was dismissed to wait for follow up paperwork. We then waited in the waiting room and got an invitation to the Grand Rapids oath ceremony on Aug 17. It seemed that everyone interviewing that day was going to the grand rapids oath ceremony. They were calling up the people who interviewed and giving them all the grand rapids information.
Anyone know about how long the oath ceremony process should take? Have to figure out how much time to take off work.
