This study investigates international students' life adjustment in Eastern Taiwan by utilizing a questionnaire design. A total of 104 students participated to complete the Life Adjustment Questionnaire. Several predictors (gender, differences in academic majors, and study levels) were studied in this survey. The results revealed seven important points, including the validity and reliability of the Life Adjustment Questionnaire, the degree of adjustment, adjustment across gender, the correlations among dimensions of adjustment, adjustment across majors, adjustment across study levels, and the interaction among gender, major, and study level together concerning adjustment. The study gives some implications for further research and recommendations for universities related to international students.
