i got mine
I think the way it works is:
(after first FP results already in, first FP notice is machine generated)
1) case is sitting on the shelf
2) case is assigned
3) rfe is issued
4) rfe response received
5) case goes into security check (your file goes on "special" shelf)
6) every two weeks they check if security check result came back
7) when they get the results, case is assigned again
8) then a person who opens the case finds out that FP needs to be redone
9) second FP notice goes out
that's why i think we are not getting second FP exactly after 15 months. Because it takes longer for some of us to get security check results.
They are not very good at doing stuff in parallel.
