This chapter argues that acculturation for many transnational immigrants are essentially a contested, dynamic and dialogical process. In particular, it uses examples from the Indian diaspora to demonstrate that such a dialogical process involves a constant moving back and forth between various cultural voices that are connected to various sociocultural contexts and are shaped by issues of power and constructions of otherness. In contrast to cross-cultural psychology's conception of acculturation, it uses selective examples from an extensive ethnography done on the Indian diaspora to highlight the larger sociocultural and political contexts that are implicated in both the dynamics of acculturation and the dialogical formation of immigrant identity. The dialogical model of acculturation not only highlights the tensions and contradictions of living with hyphenated identities in the First World, but also poses a challenge to cross-cultural psychology's notion of acculturation strategies in general and the concept of integration strategy in particular.
