I am in the same boat - I140 is approved almost a month ago, but I485 is not transferred yet. it’s still with Nebraska Service Center

I also filled concurrently on Aug 2021 with I-140 premium, still waiting for I-485 approval. It's unknown how USCIS function, I guess it depends on your luck. Good Luck

Same boat! I have my 140 approved 94 days ago. my case was transferred to NBC one month latter, and I am still waiting for my RFE.

following, I am on same boat- I140 approved around 40 days ago and still waiting for i485 to be transferred to nbc or processed at texas.

same case. 485 transferred to nbc but still no progress despite current PD even with June visa bulletin

i can tell you it took mine 8.5 months. I filed oct 21 and file was moved July 22

i-140 approved dec 21. filed i-485 oct 21. still pending.
