Yes I found that out the first time. All docs must be in one file. You can select multiple files and hit print to PDF doc to save them on your hard drive without actually printing them.
The other problem is the question of where else you will stay and what area. I have no idea. I like to book a Hotel for 1-2 days then look for another place once there. As most people do I'm sure.
I am flying out of Canada. The visa office in Vancouver won't accept info through email or even reply promptly. I tried all day phoning with no answer.
Sounds like I will have to change my return flight 2 times at $350+ a pop. This is way harder than it should be.
The first rejected visa took 16 days. I really want to stay 90 days to see the whole country, but the airlines may only let me stay 45 as I don't have proof of a 30 day extension. What a mess.
