i sent an email to italian embassy to request for fast track processing since our travel date is march 29 and pick up date was march 5. i got a reply with one word.."noted"
according to call center, the average processing time is 15 working days. in your case, you have 20 working days to work on.
i also wrote in the letter of intent in bold format our request for fast track processing stating our flight date just so they'd be aware when processing our application. i hope it works.
