Free movement of people in the European Union (EU) is currently under attack by certain political and media sectors across Europe, with proposals arising on how to limit its scope. At the same time, other regions in the world are adopting free movement regimes. This is important to highlight as it allows us to demonstrate that the EU’s free movement regime is not an anomaly as its opponents often argue. It also enables us to compare how different regions function in this area which can lead to ideas and proposals for refining legislation and policies. As such, current debates on the construction of a South American citizenship as well as the MERCOSUR Residence Agreement, effectively establishing an open border area in the region, deserve our attention in Europe.
