Based on reading feedback from a previous USCIS worker on Reddit, it probably isn't that they are trying to make their numbers look better. They also had a move from one building to another this year (I think in June?). All of the files are real paper, not electronic. This can lead to all sorts of organization problems where files are in a box/s and put in a place out of sight or on the bottom when they should have been on the top. They do not go in order. I've watched numerous around my number be approved while mine still sits waiting. Do they separate by country? By difficulty of case? Mine is very straight forward with no criminal background or conflicts yet is still waiting 6 months now. Some that submitted their request this month have been approved while others from Feb are still waiting. They also have a high turnover rate while it is very difficult and takes a lot of time to hire new workers. There are so many variable that we don't know about how this agency operates other than they give approvals, denials, and RFEs.
We can speculate why these things happen but truly, they are a rogue, on their own type of agency where not any outside entity like congress, governors, senators, can urge them to do anything. They are a necessary agency that is very important while also treated as subpar without resources to do what they need to. We are all stuck in the middle just hoping to be with someone we love.
Try to keep your spirits positive and hope for the best so we are all putting positive energy out. Wishing all their happily ever after π
