Some South Asian immigrants in the United States experience acculturative stress as a result of sociocultural differences. Social media is a tool that can facilitate the process of acculturation of some ethnic groups in the United States such as Hispanics. The specific problem that the researcher examined in this study was that the use of social media as a tool that can facilitate the acculturation of South Asians may be inappropriate because of cultural beliefs and practices. The purpose of this qualitative phenomenological study was to explore the lived experience of South Asian immigrants regarding the role of social media in acculturative stress and the process of acculturation to the United States. The sample consisted of 17 South Asian immigrants in the United States, whom the researcher purposefully selected. The researcher conducted individual face-to-face interviews and analyzed the qualitative using the modified van Kaam method of phenomenological analysis. This study is significant because the findings can provide insights that may be instrumental in the enhanced acculturation of South Asian immigrants in the United States. The results revealed that South Asian immigrants experienced social media as a vital tool for acculturation, and experienced more advantages than disadvantages in using social media to acculturate. Social media was experienced to be significant in adapting and learning cultural pointers; connecting with friends, family, and the host culture; connecting with friends in the new culture, and instantly acquiring help. Because the findings indicated that connecting with other immigrants eases the stress of acculturation, agencies seeking to facilitate this process should encourage those not familiar with social media to learn to use it, perhaps through community outreach programs.
