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

The United States resisted restrictionist immigration legislation in the late twentieth century, providing an anomaly for those who would expect restrictionism in times of economic recession. According to some expectations, labor unions would be part of a coalition that in such times would restrict migration to reduce job competition. This reasoning draws on a state-centric approach and assumes that effective barriers to entrance exist. If one alternatively assumes that states cannot fully regulate the socioeconomic forces driving migration flows, then one may expect labor unions to abandon their supposed preference for restrictionism and instead organize immigrant workers. In that case, unions would prefer migration law that accommodates the transnational migrants' interests. The data provide some support for this argument. The perspective of complex interdependence, which emphasizes transnational relations and the blurring of foreign and domestic politics, can enhance understanding of immigration policymaking.
