Citizenship

I attended my naturalization interview in Newark, NJ office on April 13. My appointment was at 7 am and my name was called around 9:15 am. I passed the civic and English tests and the officer went over the application with me and asked questions. He told me that everything looked good but he could not make a decision since he hadn't received my complete file from Nebraska Service Center. I was told I would be getting a letter in 30-60 days about their decision when my file is reviewed or they would let me know if I needed to provide more info or documents. He also mentioned that I might be asked to come back for a second interview but he said it was unlikely. I was very disappointed that after waiting for over a year I had to wait even longer. Has anyone had the same experience (with Newark office in particular)? Your insight will be greatly appreciated.
