The new immigrants coming to the United States and establishing ethnic congregations do not abandon religious ties in their home countries. Rather, as they communicate with family and friends left behind in their homelands, they influence religious structures and practices there. Religion Across Borders examines both personal and organizational networks that exist between members in U.S. immigrant religious communities and individuals and religious institutions left behind. Building upon Religion and the New Immigrants (2000)—their previous study of immigrant religious communities in Houston—sociologists Ebaugh and Chafetz ask how religious remittances flow between home and host communities, how these interchanges affect religious practices in both settings, and how influences change over time as new immigrants become settled. The study's unique comparative perspective looks at differing faith groups (Catholic, Protestant, Buddhist) from Argentina, Mexico, Guatamala, Vietnam and China. Data on ways in which historic, geographic, economic and religious factors influence transnational religious ties makes necessary reading for students of immigration, religion and anyone interested in the increasingly global aspects of American religion.
