This interview-based qualitative study aimed to understand the acculturative experiences of marriage-immigrant women in South Korea. Filipinas, who are married to Korean husbands, migrated to South Korea to live with their husbands, and could speak English, were recruited for the research. Interviews with 15 Filipinas were analyzed. As a result, the stories of each of the research participants were reconstructed based on their interviews, and three common themes and 11 subthemes emerged from the constant comparison method are presented. First, marriage-immigrant Filipinas learned about the role and position of a daughter-in-law in South Korea. Second, as mothers with foreign backgrounds, marriage-immigrant Filipinas' motherhood had to be negotiated. Finally, marriage-immigrant Filipinas actively engaged in developing extrafamilial support in South Korea by expanding their horizons.
