I am currently in the process of filing the I-140 Petition, the PERM labor certification stage took me about a year, so you still have a long time to wait. I recently saw a video on this topic https://www.youtube.com/watch?v=3tzIHJczSTM there is general information about the duration of all stages of obtaining an EB3 visa. If I'm not mistaken, the priority date for PERM is November 2023 now. If you need general understanding and approximately how much time it will take you to obtain a green card, you can watch the video. We just have to be patient and everything will definitely happen.
