I checked when I flew into yul on my application (had lots of time). Canada side approved it and it's pending on the usa side. Called up my local GE office and left them a message. Figured it wouldn't hurt. After next week, I won't be in Canada until Dec, so hopefully it'll get approved soon.
At worse I'll take a road trip to Detroit.
What's the maximum time one can wait after approval to schedule a appointment?
