I am applying for CanadianCvisa online from India. I applied for visitor visa for an academic conference on 23rd november. My flight is on 28th December to Canada. On CIC website, my application is being processed. I have no idea at what stage it is. I am not sure until what date should I wait for their answer. Or else, whether should i request for an emergency service or something through web form. If I should, then when should I do it?
