This study investigates native English speakers’ change in perception of world Englishes as a result of their study abroad experience in Korea. Two college students from the United States participated in this study. Data were collected through individual interviews. Three themes regarding the research question emerged from the data analysis: (1) Enhanced awareness of English as an international language, (2) Perception of teachers of English, and (3) Perception of varieties of English. Since coming to Korea, the participants became more aware of the power of English, the advantages of native English speakers, and the status of English as an international language. From their teaching experiences, they found that native speaker teachers were favored in Korean English language teaching (ELT), and that native speaker teachers were differentiated by race or ethnicity. They admitted the existence of Korean English. They viewed outer circle varieties of English as English, but they believed that the use of English is limited in the outer circle. They agreed that native varieties are equal to each other and recommended American or British English as the teaching model for Korean ELT.
