The purpose of this study was to help parents, educators, and policymakers understand how to help transnational children adjust to their psychological challenges at school in the United States. A total of 109 Korean transnational adolescents aged 11 to 19 participated in this study. They had been staying in the country alone or with one of their parents or relatives. Students were assessed using the Child Depression Inventory (CDI ) and a questionnaire investigating factors such as school level, age coming to the U.S, English skills, and numbers of close Korean friends, and non-Korean friends. Findings showed more male students than female students in the High-depression group. The findings also indicated that less depressed students seemed to have higher ethnic identity and higher self-esteem. They were more satisfied with their lives and better adjusted socially, and they behaved better at home and school than the more depressed students.
