Except for Mexico, there are now more Latino-origin people in the U.S. than there are people in Spain, Argentina, Colombia, or any other Spanish-speaking country. In fact, the nation is experiencing the greatest demographic transformation in the last 100 years of its history. As former schoolteachers of immigrant children in Texas and California, the authors have witnessed this demographic transformation firsthand in schools where their students' backgrounds and communities included both first- and second-generation Latinas/os. Today as educational researchers and professors who prepare teacher candidates, the authors are even more intrigued by the social, cultural, political, economic, and educational issues related to this population shift. Their intrigue stems from the unique opportunities that these waves of Latina/o newcomers bring to society as well as from their concerns that many in the field of teaching do not quite understand nor appreciate the complexity of Latina/o immigration. For these reasons, the authors assembled a collection of studies that address the ongoing transformation of the country's landscape--one that includes immigrant transnationalism "as a long-term process which may be viewed, from an analytical perspective, as a trajectory, or rather as a multiplicity of potential trajectories." Latina/o immigration in the U.S. has both a long history and a variety of social actors from different regions of Latin America, revealing many contours of transnationalism--including transnational projects with lengthy trajectories and others with new and recent intensity. In this article, the authors provide demographic information on the U.S. Latina/o community, followed by a discussion on transnationalism as an important lens with which to "see" immigrant students in general. They then offer a description of the work that has been published by scholars focusing on transnational Latina/o families, complemented by demographic information on Latina/o students and a brief treatise on why more research should combine Latina/o students, transnationalism, and education.
