I will speak specifically about the U.S. because that is what I am most familiar with. Currently, there are pretty good specific requirements for Canadian artists to go across to the U.S. The P2 visa process can include support crews. There is some credibility to go through, but it can include support crews, lighting crews, etc. What we would like to see is just a little more control over what's coming into the country.
