Please never lose hope. Fight for your rights. You can sue USCIS for delay on your own, my friend did it for his delayed case, and got papers within 45 days. Do youtube search to learn more about it "writ of mandamus pro se"

Thanks for sharing. I did it on the App "Inmigra USA" the community of Immigrants in the United States. inmigrausa.com There are immigration lawyers and free collaborators. Stay up to date on news of interest to the Latino community. Search Inmigrate USA. I chose the Florida community, it looks like they are starting now, so I recommend you choose Florida. Busca inmigra USA el app del inmigrante, de verdad es muy buena tambien. Thanks!!!
