Hello. I had my interview, was approved and had the same day oath. Boston. Everybody I encountered was nice and friendly. It was a long wait from December, but the interview was fine and everything that day went smoothly. The civics questions were a random mix, answered all, the writing portion was easy. I updated travel since application, no documents were asked for apart from passport I on, green card and current passport, but i had a lot of docs with me. My case is relatively uncomplicated though, so your situation may be different. The ceremony was sweet. Most people (it was early in the day) were not same day oath and it was a lovely mix of friendly people in celebratory mood. Good luck everyone.
