This study examines the social factors and bilingual education for the children of international couples in South Korea. Previous studies identified two negative factors for bilingual education based on destination and immigrant characteristics: resistance from local spouses and the immigrants’ need for assimilation. We further develop the concept of global language status, which may moderate these effects. Using the 2015 Korean Multicultural Family Survey, we conduct regression analyses to test the two factors based on the origin country of immigrant wives. The findings show that the global language status is a meaningful factor that impacts the direction of the local resistance and assimilation effects. Korean husbands’ decision-making power on children’s education is significantly associated with a decrease in bilingual education. Korean language proficiency and citizenship as markers of assimilation also affect bilingual education, but they show a decrease for Chinese wives but an increase for Southeast Asian wives.
