I filed my N-400 online at Seattle on October 9th, 2019. My wife filed on the same day.
My wife got her interview scheduled in January 2021 and got her passport already.
My interview still hasn't been scheduled. Attached my case history below, not sure what does "invalid date" mean. I contacted USCIS regarding my case, and here's response:
"Your application is currently waiting to be scheduled for an interview at the Seattle Field Office. Once an interview is scheduled, an interview notice will be mailed to your address of record. We regret that we are not able to give you a time frame for when you will be scheduled for an interview. "
But my case has been in this status for almost a year. Not sure what else I can do to make any progress, or even if something went wrong with my case...
