Description:
<jats:p>This article explores the integration of the European Union (EU) as an institution after the 2015–2016 migrant crisis. Qualitative data from elite interviews in Brussels and policy analysis, in the framework of a bigger project about the impact of the migrant crisis on European integration, highlight EU learning about new integration modes as a key theme following the crisis. The article focuses on this theme and argues that EU integration has been happening through intensive learning after the migrant crisis, whereby the EU has been exploring a combination of certain integration modes: shaping the relationships with candidate countries by restraining from enlargement; shaping the relationships with (prospectively) exiting Member States by considering fuzziness at the borders; and exploring differentiation among the existing Member States, possibly through promoting a two-tier EU, instead of universal deepening. A key contribution lies in applying the notion ‘learning’ to understanding EU integration modes specifically after the migrant crisis.</jats:p>
