Yeah I've wondered for a while about the crowing over students from Waterloo moving to the US. Would Canada be better off if there was no TN visa and companies would have to employ them in Canada? Also good point about Canada and the midwestern states being in the same boat. I'm sure Nebraska loses a decent number of software engineers to California every year.
