Résumé : This article seeks to explain whether the politics of exit forced by one state on citizens of another in the past influence the politics of entry of present ethnic nation-states. It concentrates on the Karta Polaka (Card of a Pole), originally enacted in Poland in 2007 within the framework of the politics of belonging as a response to the perceived moral duty towards ethnic Poles “left behind” in the former Soviet Union. With time, this policy has evolved to become Poland's entry policy of choice for incoming ethnic Poles from the diaspora. Through a review of the literature on politics of belonging, exit, and entry, an analysis of the context and by tracking changes within the law itself, this paper assesses the development and scope of the Karta Polaka. The causal effect correlation between the development of entry policies in ethnic nation-states and the exit policies of another is confirmed.
