So I'm from Canada, and from what research I've done, I understand that there are a limited number of Canadian agents and they are all very difficult to get published with. So is it worth my time to simply query american agents? I realize that usually an agent takes %15 from domestic clients and %20 international clients; does this change if I have an american citizenship, even though I'm living in Canada? I may be mistaken on a few of these details, so feel free to correct me if I'm wrong.
