Family Based Greencard

I filed I-751 application to Texas from Virginia on Apr/30/2019 and received 18 months extension letter on May/10/2019. My biometrics have already been successfully completed on Nov/18/2019. Moreover, I lost my I-551 expired 2 years validity green card after my I-751 application’s biometrics were completed (same day) on Nov/18/2019 and now I have I-551 stamp in my passport from local USCIS field office through infopass appointment.

Recently, I called USCIS 2 weeks ago and I was informed that my case has gone outside normal processing time and due to this USCIS representative on telephone generated case inquiry and told me that I will receive a response in 30 days. She also told me my case is in National Benefits Centre, Lee Summit, MO.

Now don't know what happens next with my application? I mean how long further they will take to process it? Because when I check status through USCIS website it only shows “as of Nov/20/2019 case is ready to be scheduled for an interview”.

In March 2020, I also filed N-400 application as my time for Naturalization was also completed and I have received letter from USCIS in mail that they have received my N-400 application and reviewing it and will also be conducting background check in order to identify any issues that needs to be addressed.
