Engagement with institutions from migrants’ country of origin, both in the destination country and in the country of origin, is distinct transnational behaviour. This study investigates the impact of geographical distance on the institutional engagement of migrants from Czechia in five global regions. We examine how geographic (physical) proximity to Czechia shapes institutional engagement with the country of origin and identify factors beyond distance influencing institutional engagement. We analyzed survey data from Czech emigrants (N = 940) in neighbouring countries, Western and Northern Europe, Southern and Eastern Europe, overseas Anglo-Saxon countries, and other countries. We found that respondents from all more distant regions have higher levels of institutional engagement in the destination country than those from neighbouring countries. Length of stay and education were relevant factors for all selected regions, while place of residence (living in a metropolis) and the level of transnational behavior had varying impacts across regions. Concerning institutional engagement in origin country, the level of transnationalism was consistently the strongest predictor across. Transnational studies should incorporate geographic variables, such as physical distance into their conceptual frameworks. We expect our findings to be generalizable to other countries similar to Czechia, i.e. high-income countries whose citizens benefit from liberal visa regimes.
