Immigration

Immigration is the international movement of people to a destination country of which they are not usual residents or where they do not possess nationality in order to settle as permanent residents.^[1][2][3][4] Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however.

Economically, research suggests that migration can be beneficial both to the receiving and sending countries.^[5][6][7] The academic literature provides mixed findings for the relationship between immigration and crime worldwide.^[8][9] Research shows that country of origin matters for speed and depth of immigrant assimilation, but that there is considerable assimilation overall for both first- and second-generation immigrants.^[10][11]

Discrimination based on nationality is legal in most countries.^[12] Extensive evidence of discrimination against foreign-born persons in criminal justice, business, the economy, housing, health care, media, and politics has been found.^{[13][14][15][16]}
