Over the past 20 years, the number of higher education students studying internationally has more than doubled (Institute of International Education, 2020b; Institute of International Education, 2020c). Studies find that while students are adapting to new countries, there is the potential for negative psychological outcomes (Ward, Bochner, & Furnahm, 2001). This paper suggests that the application of positive psychology can prepare students to adapt well to a new country. We will start by reviewing the theoretical models of cross-national transitions, the positive psychology literature on strengths, mindfulness, exercise, gratitude, savoring, optimism, and thinking traps. Then, we will suggest teaching the application of these concepts to students through workshops before their international experience starts.
