The ya es hora campaign is an historic nonpartisan Latino civic participation campaign launched as the Latino community’s action-oriented follow-up to the immigrant mobilizations of 2006. The campaign represents the largest and most comprehensive effort to incorporate Latinos as full participants in the American political process, linking naturalization to voter participation and Census enumeration under a single message: It’s time. This report analyzes the extent to which ya es hora contributed to measurable increases in the number of naturalizations between the 2003-2006 and 2007-2008. It also provides the results of a survey of people who received assistance in the naturalization process from organizations participating in ya es hora. These responses provide important insight into the motivating factors that can be credited for increased naturalization rates, voter registration, and voter turnout among Latinos.
