Guys, I sent to USCIS an online inquiry that my i751 is outside of processing times and USCIS sent me a letter stating that:
"On September 8, 2022, we administratively closed your Form I-751 Application for Naturalization, Receipt Number xxxxxxxxxxx, and mailed you a closure notice. Please follow the instructions in the notice."
I'm confused why they called I-751 application for naturalization? I have never applied for naturalization nor did I apply for citizenship. I have also never received any notice with instructions and my online USCIS doesn't show any closure. Would USCIS just close my case after 3 years of waiting? I'm stressed out.
