Can Canadians join the CIA

You can become a FBI agent, but not as a Canadian citizen, you also can't have a joint citizenship (Canadian and US). But, the process to become a US citizen is long. I recommende that you stick with Law enforcment in your region. Plus, getting in the FBI is not an easy task.

I hope the info helps you out! And remember, FBI is not like Hollywood represents it, it's allot of hard desk work.
