There is no real time data of which month they are on. The best you have with the USCIS is the processing times page which will give you the time it took to adjudicate %80 of cases.

This website (Visa Journey) is pretty good: https://www.visajourney.com/times/k1-fiance-visa-historical/

Thanks you so much for your reply, It’s a really good page to tracking it 🥹🙌🏻

just remember it’s based off users on the site none of the information is from USCIS itself

No problem! Anonymous user is completely right, it is based off of user data - but it’s probably as close as we can find to real time tracking outside of the general USCIS estimate! 😊
