I am a international student in US, and try to get a visitor visa in Canada. I was planning go back to China in this May and stay in Canada for 2 days before that. So on April 5th I mailed my I-20, passport and other file to the Canada visa office in LA. The application arrived on April 8th. I am stupid enough that I have not bought a round track number. Now I am so worried about whether I can get my passport back before May 6th. Otherwise, I can not go back to China this year. Does anyone has any ideas what I should do now, and how long it will be take to obtain a visitor visa for students like me. Thanks.
