The present study is a longitudinal examination of the role of Facebook on the cultural adaptation of Muslim immigrants to the United States (n = 379). Immigrants’ use of Facebook affects interactions with the dominant culture and with the ingroup. Respondents were asked about their use of Facebook, motivation to culturally adapt, and perceptions of the US at two different points in a 6-year period. Analysis revealed the following. Muslim immigrants to the US from 2006 to 2012 who used Facebook more for social interaction with the ingroup were less likely to be motivated to culturally adapt to the US dominant culture and these same immigrants were more likely to have a negative perception of the US dominant culture as their Facebook use increased.
