Hi everyone, I applied for Canadian visa from Nigeria to attend career related conference and I was denied, their reasons are, travel history and employment status, The truth is that I'm currently working since Dec 2015 till day and I've travelled to Canada last August for a conference and I spent only 12 days. Now I'm going on 60 days vacation to USA with b1 b2 mutiple entry visa, which will expire Oct 2018, can I apply from USA to attend a conference in Canada April.
