Hello, I will be having couple of meetings with various universities in unites states for collaboration on research activities.I have booked the to & fro tickets also. Leaving from India on June 10. I am also planing to visit a Canadian university and have their invitation letter. My concern is ,i can apply the canada visa online and get it processed 12 days( as per processing time for india in web page of canada) . If ,i am granted visa, then passport has to be sent to the canada office through post for stamping the visa. 1) Any body knows how long will it take for passport visa stamping and get the passport back.(in india) 2) If after submitting the application and there is an increase in online processing time and if there are chances that i wont get by passport back on time , can i start my trip.My entire itinerary goes into chaos if i didn't start on time. Can somebody help..
