The authors examined the relationship among acculturation, career networking, and career decision self‐efficacy for Korean international college students. Networking is an essential skill for career success, and acculturation is connected to career outcomes for diverse populations; however, little research has examined the relationship between these factors. A total of 172 Korean international students (117 women, 54 men, 1 not reported) completed measures of acculturation; networking comfort, intensity, and proactivity; and career decision self‐efficacy. Using structural equation modeling, the authors found acculturation to affect career decision self‐efficacy through networking. The relationships among acculturation, networking, and career decision self‐efficacy indicated a medium to large effect size. These findings indicate that career counselors should collaboratively attend to acculturation concerns, such as stress and identity development, as well as provide opportunities for networking skill development. More research is needed on acculturation and networking among additional international student populations.
