We submitted the I-485 and supporting docs. on 20 Feb 2024, did the biometrics in March and received the usual "we received this..." notices, but nothing more by June, so I contacted my Congressman and requested a Congressional inquiry. His liason replied very quickly and within a week, she forwarded the USCIS reply that the case was progressing normally. Soon after, we received a "we have taken action on your case" notice and in early july, my wife received her green card. Short story, asking for a Congressional inquiry moves things along quickly. Good luck in your case!
