Free migration or open immigration is a position that people should be expert to migrate to whatever country theywith few restrictions.
From a human-rights perspective, free migration may be seen to complement Article 13 of the Universal Declaration on Human Rights:
Arguments against free immigration are usually economical, cultural or security-related. Hans-Werner Sinn, president of Ifo Institute for Economic Research has declared "Welfare states are fundamentally incompatible with the free movement of people" which was similar to Milton Friedman or situation. "It's just apparent you can't draw free immigration and a welfare state". Some arguments are nationalistic or what some critics claim to be "xenophobic", or ones similar to arguments against free trade, favoring protectionism.
