Well, I think I have now seen it all.
I went for my second biometrics last week. I asked them why I was asked to do biometrics again and the supervisor at the site couldn't find any record of my biometrics taken in September 2021! I had the stamped documents - so they tried very hard to figure out what happened but couldn't come up with an explanation.
When I had done the biometrics in 2021 September, the person doing it was Asian (this is in Oakland, CA). I couldn't understand a single word she was saying and she was getting frustrated that I was unable to understand her directions. She was not able to get good prints for 3 fingers. She even shouted at me at one point. Anyway, my wife's biometrics went fine and we came home. Now I believe that she never entered my biometrics in the system! There is just no other explanation. I am super pissed. This time, the supervisor confirmed my biometrics were received and my status updated by the time I got home. Let's see if the background check happens quickly and if my application can be processed this month or in October. My PD is May 2011 and I had downgraded to EB3 in Nov 2020. Didn't interfile back to EB2 based on Fragomen's advice. I have already replied to the medical/birth/marriage RFE in July. Let's see how long it takes now that my biometrics are finally there after a year!
Ugh.
