The present study explores and investigates how a Korean-English bilingual speaker is influenced by her native culture during her acculturation process in the United States (U.S.). This linguistic research study is designed around three main themes. The first theme is the cultural adaptation process of the participant, which is analyzed based on the participant's perceptions about Korean daily life and customs. The second theme refers to exploring the participant's acculturation process within the U.S. along with her socialization stages. For the third theme, the participant's intercultural awareness towards her native culture is explored. The interview data analysis confirmed that the participant experienced a culture shock within her first school year in the U.S. The findings of the interviews indicate that the participant applied particular strategies to overcome her culture shock in order to adapt a new way of life, which would be informative for improving culturally responsive curriculum development strategies.
