Non-pejorative term for behaviour that discriminates against people based on their birth place [duplicate]

Solution 1:

Nativist seems to fit: "Nativism is the political position of demanding a favored status for certain established inhabitants of a nation as compared to claims of newcomers or immigrants. Nativism typically means opposition to immigration and support of efforts to lower the political or legal status of specific ethnic or cultural groups because the groups are considered hostile or alien to the natural culture, and assumptions that they cannot be assimilated" http://en.wikipedia.org/wiki/Nativism_(politics)

Solution 2:

It is xenophobia - because it's about them being foreign. Whether or not immigrants consider themselves foreign, the people who say these things consider them to be. I can't find a definition of xenophobia that doesn't call it the fear/dislike of strangers/foreigners (there might be one but I can't find it).

Solution 3:

In France, that kind of discrimination or prejudice is euphemistically referred to as national preference or national priority.

That's just a case of barely disguised ultranationalism and overt populism.
