The purpose of the study is to analyze the satisfaction and needs of undergraduate international students regarding the educational service and to suggest future measures for service improvement. The primary requirement for the academic adjustment of international students is to reveal how satisfied they are with the current educational administration service and what their needs are. To investigate the satisfaction and needs of undergraduate international students regarding the educational administration service, a survey was administered to 395 international students at 12 local undergraduate institutes. Results of the survey showed that the satisfaction of the learners in Chungcheong Province and Gangwon Province tended to be lower than that of the learners in the capital area, Gyeongsang Province, and Jeolla Province. Moreover, a lower level of satisfaction was shown from groups with smaller numbers of undergraduate international students. With regard to language group, dissatisfaction with the administrative service among learners from Vietnam and other Asian locales was higher than learners from other regions. The study results therefore suggest the need for universities to provide customized administrative support for international students.
