We applied in NYC and I believe we had to wait 8-9 months for an appointment in August 2011. However I think they were short-staffed so they cancelled it and then the soonest we could get was February, 2012. We needed to get/correct a few items, and had to wait another year. As if to compensate, after that appointment early this year, we received our letters from the Consulate within 2-1/2 weeks. We were stunned! I'd done a search of these boards and thought we'd wait 2-6 months. No idea why.
In 2001, I was a legal resident of Mexico and submitted my documents (originating in the Philadelphia consulate jurisdiction) to the Italian Embassy in Mexico City. The Embassy was kind enough to translate all of them at no cost to me and because I'm an American citizen and not a Mexican citizen, forwarded them to the Philadelphia Consulate for processing. I had my Italian passport in hand within six months (issued by the Guadalajara Consulate at the instruction of the Philly Consulate) after which I moved to Italy and have been in Italy ever since. High marks to both the Mexico City Embassy and the Philadelphia Consulate.
Fast forward 12 years. I recently received a call from IPS Italy (Philly) which kindly set an appointment in October this year for my sister to submit her own documents with instructions that she need bring only her own birth certificate, marriage license and marriage certificate, translated and apostilled since the consulate already has our family's case work on file. Had my sister's documents been ready at this time, IPS Philly was prepared to set an even earlier date for her appointment. Once again, high marks for the Philly Consulate and for IPS.
