How would you conduct immigration policy?

Immigration has obviously been a big issue for Trumpians, and the Dems have often responded with a different more welcoming immigration policy. It’s a very complex issue, obviously, but what would be your immigration policy be? Would you have open borders? Would you have immigration based upon skills which would mean you would give high skilled people priority? Would you have closed borders?

Personally, I take a classic libertarian line in that I am in favor of completely open borders. Anybody can come or leave as they wish as long as they are peaceful. Immigration increases growth of the economy. But conservatives and many protectionist liberals disagree.

How do you feel?
