We Libertarian are ourselves too picky about people being "pure" in their Libertarian beliefs. For example, there was a poll of 200 Libertarians in our Party's monthly newspaper, about the proper size of the federal government. Answers ranged from zero percent of the current size to 50% of the current size, with a median number of 12% (as I recall). Far too many Libertarians seem to be quick to say that the folks in the 12-50% range aren't really "pure" enough to be libertarians. And then they'd say the people at zero percent are really anarchists. As a Libertarian, *I* say anything from 0 to 50% of current spending would be so much like heaven--and so different from Democrats OR Republicans--that I'd be insanely happy.
The key things about immigration, in my opinion are: 1) completely eliminate federal government services that encourage people to come here without working, and 2) completely eliminate quota restrictions. Any idea that we shouldn't be allowed to screen them for things like communicable diseases, or hostility towards the U.S., is wrong.

I would also like to see the emphasis placed on actually becoming a citizen with mandatory classes on what makes liberty work and how the government is intended to function. Furthermore, they should be able to demonstrate enough english to actually function safely in our society.
