I applied for sponsorship in May of 2014, they sent the application back in August saying I was missing a form which I wasn't so I went to the back of the line again. I have been getting emails for the last month asking me to send in proof of my sponsors residence in Canada and asking me if my address is correct etc, they said my application in in Queue to be looked at by an immigration officer. I hope its good news and it doesn't take much longer
