My personal experience is 21 months of delay without
a final decision or the oath ceremony being scheduled
after passing the citizenship test at the
interview, without any reason for delay or progress to
report. No foreign name, from Canada, no record,
so it should have been easy.
The Miami office appears completely fouled up in
its processing. After 2 tries at correction they still
sent yet another permanent resident card for my son
incorrectly identifying him as female. It takes a year
to wait for the "corrected" version each time.
I have heard that there are many, many people that
this office has put in limbo for citizenship, due to
bureaucratic mistakes, resulting in their waiting the
rest of their lives for their oath ceremonies to
be scheduled, through no fault of their own, according
to attorneys who no longer take on citizenship cases
for this reason. I was also told by a friendly adjudicator
that often errors are made, and affected files are then
misplaced, or languish somewhere without anyone to followup
on them. Sometimes they are then even deemed abandoned
and the applicant never even contacted.
When I was making a status inquiry in person, which basically
tells you nothing other than what you already know - that
nothing is happening - I encountered a number of people who
had made numerous trips to find out the status of their oath
scheduling multiple times, without any end in sight. We are talking
years here.
I would never have applied in Miami if I had known this beforehand,
but rather waited until I had moved out of state.
