The subject of transnational citizenship is even more important when migration involves groups who are excluded and marginalized in countries of origin and destination, such as indigenous people. Therefore, the central question of this paper is whether indigenous migrants actually organize to negotiate citizenship in a transnational context. Based on the data collected from my ethnographic research in Los Angeles, I argue that indigenous migrants from Mexico’s southern state of Oaxaca negotiate citizenship through a well institutionalized community based on a diverse network of migrant organizations which open wide transnational sociocultural, political, and economic spaces to reconstruct the boundaries of citizenship. The basic initiative to build transnational community citizenship comes from the indigenous diaspora in LA itself instead from political counterparts. In this process, they collaborate with various institutions and organizations on different levels in the United States and in Mexico.
