How are the rights of migrant workers mobilized in non-immigration regimes? Drawing on an ethnography of human rights NGOs in Israel and Singapore, two countries that share similar ethnic policies but differ in their political regime, this study contributes to scholarship on migrants' rights mobilization by expanding cross-national analysis beyond the United States and West Europe and diverting its focus from legal institutions to the places where rights are produced. Findings show that differences in the political regime influence the channels for mobilizing claims but not the cultural politics of resonance that NGOs use when dealing with the tensions between restrictive ethnic policies and the expansion of labor migration. While restraints in authoritarian Singapore operate mainly outside the activists' circle, in the Israeli ethno-democracy they operate through self-disciplining processes that neutralize their potential challenge to hegemonic understandings of citizenship. Paradoxically, success in advancing rights for migrants through resonance often results in reinforcing the non-immigration regime.Recent comparative studies on migrant workers' rights 1 shed light on how national fields of power shape and are shaped by legal mobilizations (Bloemraad 2006;Bloemraad and Provine 2013;Kawar 2011aKawar , 2012. Bridging the comparative migration studies' interest in national settings and sociolegal mobilization perspectives, this scholarship underscores the complex dynamics of rights making when activists engage in settings with varying institutional configurations and cultural repertoires. Despite its interest in legal pluralism, much of the cross-national scholarship We thank the NGOs staff and activists in Singapore and Israel that took part in the study for their participation, openness and insights.
