I751 has been pending since march 2019. On April 2022 submitted N400 application . Interview for N400 was scheduled for 12/05/2022 nothing was said about my pending I751. A week before the interview I received an email about a combo interview for I751/N400 and it also said to bring my wife. When officer came out he said your wife can’t come in because I haven’t received your file for i751 so I’m just gonna do the N400 interview. I was so disappointed. Officer went on with the N400 interview. He didn’t want to see any of the joint docs and pictures I had. He only asked our child birth certificate, last time I traveled out of the US, my wife US passport, marriage certificate, and my green card made copies, and said he’s going to request my file but can’t make a decision today .But he gave me a paper and highlighted that I passed the civic test and that I would be notified of a decision by mail, and I won’t get an interview for I751 ,Just wait for it to be approved and they can schedule ceremony. He stated maybe by next week he’ll get the missing files. Should I be worried ? I’m so anxious because I have no idea how long this will take
