Abstract
How should we conceptualize membership, citizenship and political community in a world where migrants and their home states increasingly maintain and cultivate their formal and informal ties? This study analyzes the extra-territorial conduct of Mexican politics and the emergence of new migrant membership practices and relations between migrants and home states. Standard globalist, transnationalist or citizenship theories cannot properly contextualize and analyze such practices. I propose that we rethink the concept of membership in a political community not only as a Marshallian status granted by states, but also as an instituted process embedded within four other institutions and processes: home state domestic politics; the home state's relationship to the world system; a semi-autonomous transnational civil society created in part by migration; and the context of reception of migrants in the United States. A main conclusion is that the state itself plays a key role in creating transnational political action by migrants and new migrant membership practices. The article draws on printed sources and interviews and ethnography done since 1990.
