@Family I hope the appeal would work for @IandI100. I really appreciate @IandI100's openness and willingness to share the experience with the rest of the folks here. It's very valuable and educational to most of us.
It's the stories like this are a bit scary. Quick timeline from that page:
N-400 filed in July 2018
N-400 denied in December 2019
N-336 filed in December 2019 or January 2020.
N-336 hearing in November 2020
RFE in July 2021
Naturalized September 2022
Sure, maybe it's an edge case and due to pandemic etc. etc.
The worst part is that:
"
Q: if an N-400 is denied based on an I-751 denial, can both decisions be addressed during an N-336 (Request for a Hearing on a Decision in Naturalization Proceedings Form) hearing?
USCIS Response: Due to the nature of USCIS processing, all applications, petitions, and requests are handled on a case-by-case basis."
From here https://www.dhs.gov/publication/follow-questions-and-answers-uscis-processing-concurrently-pending-forms-n-400-and-forms
My understanding is that USCIS can play a fool, get N-336 done and come to conclusion N-400 cannot be adjudicated due to I-751 that was denied. Please correct me if I'm wrong or missing something.
At that point the OP already waited all these months for a reply that they need to resubmit I-751.
Did FOIA show AR-11? Does it normally include it? Or USCIS would say "we never received it"? Is there proof it was sent?
All the best to @IandI100, I hope your appeal will work out despite my scepticism (I am an old grumpy user after all)
