Bill,
Thank you for your congratulations, and apologies for the radio silence — for some reason this board is not notifying me of replies to this thread.
Much has happened in the interim; I now have an Italian passport in-hand. Let me update the timeline once more before getting to your questions (new items in bold):
June 2020: begin eligibility research
January 2021: engage ICA, begin collecting official documents
... [other stuff, corrections, translations, etc] ...
February 2023: file in Court of Potenza
March 2023: receive hearing date
October 2023: hearing date
February 2024: accoglimento totale
June 2024: passaggio in giudicato (certificate of no appeal)
June 2024: request passport appointment at consulate (NYC)
November 2024: passport appointment at consulate (NYC)
November 2024: Italian passport arrives by mail
So, perhaps I got mixed up with the consulate appointment. It seems appointments to bring all of one's documents forward to apply for a passport run about 5-6 months out, depending on the consulate. I was unaware that this was a step that takes places regardless of one's specific tragjectory (1948 vs non-1948), and that the passport would actually be generated in-country, by the consulate, rather than in Italy. Apologies for that.
A separate matter, consular appointments to negotiate citizenship when one is
not subject to the 1948 ruling, I understand, can run as far as 2 years out, making the 1948 vs non-1948 overall time-to-wait about equivalent.
To find relatives, I researched on several genealogy websites, and finally found someone, a very distant cousin, who replied to me on one of them — it was
