This dissertation addresses the theorization of immigration policymaking from a perspective that encompasses all possible roles held in migration management. It discusses how simultaneous roles as a sending, receiving and transit country in the migration phenomenon can become intertwined and inherently affect policymaking on all fronts. Using Mexico as a case study, this dissertation finds that the most compelling variables in the construction of immigration policy are: consideration of the stateâ€™s relationship with its emigrant population; grievances expressed by civil society; and complaints of regional partners. Mexico combined emigration and immigration policy in order to produce an optimal situation for all aspects of migration management, which was done through the strategy of soft reciprocity. By utilizing international human rights norms in the construction of its new Migration Law, Mexico was able to secure legitimacy and moral authority to broaden emigration policy and enhance protection of Mexicans abroad.
