This study seeks to understand global mobility patterns of international graduate STEM students studying in the United States. Using data from the NSF Graduate Students in Science Survey (GSSS), this study investigates the political, economic, and social factors affecting students' intent to stay or go, identifying differences based on students' country of origin within World Bank defined categories of gross national income (GNI) per capita. Descriptive statistics identified factors affecting students' intent to stay or go. Chi-square analysis, and analysis of variance (ANOVA) identified differences between factors based on students' intent to stay or go, and identified differences based on students' home country GNI categories.
