Ok, folks, here goes the rant (with a question towards the end):
Background: filed N400 in March 2022, Boston field office (very comprehensive submission). 3 year rule (i751 filed in March 2021--again, a pretty impeccable submission, if I dare say so myself). I751 transferred within 4 days since the N400 submission. Currently, I am at 12.5 months mark for N400 and 24.5 for i751. I would have anticipated a combo interview by now--instead, a delightful radio silence.
I did FOIA at 8 months mark (the result suggests my files have not been touched). I reached out to the senator and the district representative (at 9months mark and 10 months mark respectively). USCIS response to all these inquiries --nada. Just restating the summary of my cases (which of course I already know...). I reached out via senator's office once again at 12.5 months--same response. I did point out to the senator's office rep that my case is outside of the 12 months mark (current processing time for Boston office). I checked previous USCIS field specific reports, all confirming that the majority of cases should have been processed by now.
Any suggestions for my next steps? At this point, I expect this process to take at least 15-16 months and I am hoping to do whatever I can to not make it even longer. Thoughts?
