Permesso di soggiorno Renewal-duplicate.

Hi Expat,

I came to florence, italy in january 2016 on the basis of a student visa. I applied for my permesso di soggiorno and received it. My permesso expires on january 11 2017, but my study course ends in may 2017.

My wallet got stolen a week ago, in which i lost my original copy of my permesso. I went to the police station and registered a complain and as per the guidance from questura i was asked to apply for a duplicate permesso in order to renew my permesso. Hence, I applied for a duplicate a week ago. My date to visit the  questura for the duplicate is 18 th january 2017 ( which is 7 days after the expiry of my permesso). I want to know when can i apply for the renewal process of the permesso? Do i have to wait till i get the duplicate copy of my permesso? Can i apply for the renewal before receiving my duplicate copy?

Thank you for the help
