This study examined acculturation and bicultural integration in organizational settings, with particular attention to the factors that influence individuals' acculturation processes; the challenges and opportunities they face; the ways in which they integrate home- and host-culture features; and the conditions that facilitate third-culture building with host-culture members. A qualitative approach using in-depth interviews with Americans living in Sweden, Swedes living in the United States, and Swedish-American biculturals having grown up with ties to both countries was used to gain an in-depth understanding of the processes of acculturation in organizational contexts. Results emerging from a grounded theory analysis identify assimilation as the predominant acculturation approach for reasons of cultural preference. Culture-specific features are integrated in limited ways and third-culture building takes place in contexts where home-culture connections exist. Bicultural individuals integrate their two cultures by alternating between them as well as blending them. Theoretical implications are discussed.
