Agreed. I came from Canada to work in the USA on a temporary visa (the TN if anyone's interested). I like the country, but as of right now I'm tied to my employer and have no freedom of movement - and even if I was on a H-1B, where there's a shot at PR, I would still be chained to my employer for effectively the next decade or so.

This is no way to treat skilled labour trying to enter your country.
