Hi, I filed my form i-751 on Nov 18 2022, and it arrived at the Phoenix PO box on the 21st. I still haven't received the form i-797 or had the payment process in my bank account. I was planning on visiting my family for New Years, and I can't leave the US without the NOA. Is anyone else experiencing delays on receiving the letter? It seems like most people that submitted in November already received their NOA. Also, does anyone know of a phone number for the USCIS that is not an automated voice?
