Cross-cultural communication scholars have looked at effects of interpersonal communication and both ethnic and host mass media uses on the acculturation behavior of immigrants for a long time. The present study employs an important network analysis concept, the social influence of alters on ego, in the field of cross-cultural communication. Using measures of alters' acculturation, English- and ethnic-language media uses, and years of residence in the U.S., a model is proposed and tested upon a sample of international students from a college campus. The results indicate that the alters' acculturation plays a central role in the pattern of relationships.
