This article provides a profile of the financial responsibilities of Mexican and Central American immigrants to their families back home. We outline the patterns of US immigrant remittances to Latin America, describe the toll on both immigrants and their families, and review research evidence on the provision and impact of immigrant support. We find that immigrant remittances are the sole source of household income for large proportions of families back home and are typically used to meet basic needs. The multiple responsibilities faced by immigrants, however, come with substantial hardship. Implications for social work services with immigrants are discussed.
