Abstract
This article examines the municipal ID card programs in New Haven and San Francisco. With a municipal ID card, undocumented immigrants can access basic city services and identify themselves with police and other city officials. The article draws on twenty-eight interviews with key stakeholders to show that city officials navigated the conflicting demands of ID card supporters and opponents to create a local membership policy focused on improving city administration, not expanding the rights of undocumented immigrants. In capitalizing on their discretionary administrative powers to develop programs that safeguard the health, safety, and welfare of all city residents, officials in New Haven and San Francisco managed to promote the integration of undocumented immigrants into city affairs without upsetting the federal monopoly over immigration and citizenship powers. This new form of local bureaucratic membership has implications for the urban citizenship literature and illustrates that city officials have some freedom to develop programs that benefit undocumented immigrants.
