Korean transnationals are defined as 1st, 1.5, and 2nd generation Korean Americans and Koreans sojourning in the U.S. on temporary visas. Three hypotheses were generated. Although similar patterns of responses emerged for all three hypotheses, only H2 was statistically supported: Korean transnationals, compared to non-Korean Americans, indicated a greater likelihood that Hallyu made them want to actively approach to Korean culture (e.g., visit Korea, form a relationship with Koreans, and learn Korean language). However, it did not influence either group to identify more with Korean identity or to share Korean culture with others. Further investigation through sub group analysis revealed that 2nd generation Koreans felt the least affiliated with Korean culture, followed by both 1.5 generation Korean Americans and non-Korean Americans. 1st generation Korean Americans and Korean sojourners were most affected by Hallyu with regard to ethnic identity and behavioral intent. Key words: Media effects, Hallyu, Korean transnationals, ethnic identity, cultural adaptation.
