Previous studies in international education have mainly focused on the factors influencing the migration of international students from developing countries to developed countries and are of great interest to the current practice of investigating the factors influencing student migration to a particular country. Taiwan is a destination for Vietnamese students to study abroad. By looking specifically at Taiwan, this study seeks to examine why and how international students from Vietnam come to Taiwan for study purposes and outlines the potential impact on institutions and institutions providing higher education that are timely and valuable and an appropriate strategy offer to attract resources. The dimensions given represent the most common and most significant concerns for student decisions. The method used in this article is the Analytical Hierarchy Process (AHP). It is regarded as a decision method that solves a problem of the complex multi-criteria decision in decomposed a hierarchy. As a development platform, the push-pull model was used to identify the seven relevant factors of studying abroad decision-making process, while the analytical process method was used hierarchically to account for the relative importance of these factors. The results of this study suggest the policymakers and institutional managers should focus on providing different types of scholarships to international students and designing multilingual websites for international students, promoting international programs with different languages, promoting language training programs for international students, and developing student recruitment strategies tailored to different study groups of international students at government levels and educational institutions.
