Openings in the wall: transnational migrants,labor unions,and U.S. immigration policy

"This article seeks to enhance our understanding of why the United States resisted restrictionist [immigration] legislation in the late twentieth century during times when one may have expected a movement toward closure, as occurred in the 1920s.... The article will supplement a state-centric approach with insights from the perspective of complex interdependence--the significance of transnational relations and the blurring of foreign and domestic politics. I will argue that the societal groups that influence the formation of U.S. immigration policy contain a transnational component, which contributes to the maintenance of relatively open legislation.... More specifically, I will argue that the transnationalization of the labor market...blurs the boundaries between foreign and domestic constituents for unions, causing unions to resist those restrictionist immigration measures that impede organization of foreign-born workers. Hence, the pressures for restrictionism are weaker than anticipated by the conventional wisdom that expects labor to lobby for closure."
