I filed N-400 online on June 25, 2020 and when I first filed, the USCIS site said estimated completion December 2020. In December 2020, the estimated completion said January 2021. In January, the completion date said March 2021 and in March, the completion date said April 2021. Now, in April there is no estimated completion date on my case at all. When I checked a couple of weeks ago it said to watch for biometrics appointment, but now even that message is gone. I know Covid has made them behind in processing, but it concerns me that cases filed after mine have already been processed and approved. My field office is Louisville...I think. First they told me Cincinnati then they told me Louisville.
