If it's 'bull', then why is CX now going through the panic of trying to get visa's...? As for my being in Washington visiting the Immigration HQ, why is that 'so' hard to believe? I made an appointment, and interviewed. I was explicitly told that you could not be 'based' in the US without documentation. You can only transit into the US to pick up an aircraft for operational reasons. It can not be a 'permanent' condition of your employment. Why don't YOU go and visit Washington and find out the same. If "there is absolutely no stipulation to how many times a HKG based Canadian is allowed to cross the border for the purposes of operating a foreign registered airplane" as you say, then why is CX rushing around to get them visa's? The fact that CX is now rushing around trying to clean it up would suggest that I do in fact know what i'm talking about. The fact that you just can't seem to acknowledge it is your problem.
