Hello, sent 751 on December 2021, got the 24 months extension right after as well as the finger prints waves. Since then we are waiting. They keep pushing back the processing time and as you may know, they are sending the 48 months extension and I think I will receive that extension very soon. So now on USCIS processing time it says 15 months and half. How do we know what month filet they are taking care of ? Also what do you think I soule expect ? Thank you
