This process is so frustrating. They have had my response from request for evidence since February and yet I still have no update on my case. I found info on the USCIS sight that said they would respond to evidence within 60 days, however the form won't let me submit an outside normal processing because California estimate is 13- 27 months (even though my case was transferred elsewhere). I mean.... 27 months. So we just wait until May 2021 until we can even request info on something we filed in Feb 2019?! My letter of 18 months expires in Sept 2020 I think.
Meanwhile my Citizenship estimate when I log in Says Nov 2020 (4 months from now!) which is obviously never going to happen!
All that said, I will just sit patiently waiting like everyone else, because that is the only choice we have anyway!
I am waiting more than 2 years at this point, extension letter expired long time ago, rolling on passport stamp...to whoever is feeling in agony after just 1year of waiting always remember it can be twice worse...good luck to everybody
