I am May 2022 filler and same as you- did everything on my own, got EAD combo cards first for 2 years, then last year renewed for 5 years. Getting Prima Facia letters every 6 months. Same as you- never received any RFEs. I just cant wait for all this waiting time to be over and get hopefully an Approval. Keep me posted on your progress because we are very very close with filing time!!!
