Immigrants typically have attachments in two directions: to the country in which they live, and to their country of origin. These attachments are often discussed in terms of integration and transnationalism, respectively. A new conceptual framework, which we call the matrix of attachment, enables us to examine immigrant integra-tion and transnationalism simultaneously. This perspective, we argue, can inspire more nuanced analyses and policy development. We use this framework to analyze variations in attachment among immigrants in Norway.
