Return of passport after medicals submission

Hi All,

Below is my timeline for Canadian PR application under skilled workers category:

NOC: 1233 Claims representative
Processing Office: New Delhi CHC
File rcvd in Sydney NS: 17th January 2011
Approval rcvd: 16th March 2011
Called for interview by CHC Officer: 10th November
Decision made and informed to me: 10th Nov 2011
Instructions and request for MEdicals rcvd: 14th Nov 2011
Deadline for submission of medicals and passport along with police clearance from Australia (studied 2 years over there) & India plus fees: 29th December 2011.

Can anyone tell me how long does it take to receive your passport back after stamping of visas by CHC delhi as I am have to back on my project in KAzakhstan for a month to handover things and leave for canada.

Info will be highly appreciated.

Thanks,

Binny
