Economic freedom demands the unrestricted movement of human as well as financial capital across national borders. However, we support control over the entry into our country of foreign nationals who pose a credible threat to security, health or property.
Since Libertarians are anti-welfare, we can take this to mean that non-working foreigners are not welcome.
I have no real problem with immigrants who come here to work. I've known several people that run construction crews and they all say the same thing about immigrant laborers: They typically out-work Americans and will actually show up on time with stunning regularity. A good number of Americans in the construction trades are irresponsible slackers with substance abuse problems and can't be relied on to come to work every day.
