There has been a considerable growth in the number of international students in Dublin, Ireland. In this paper, we first explore the broader context for this growth, showing the ways in which international student migration to Dublin has been facilitated, and the consequences in terms of the creation of different categories of international student migrants. We then discuss the experiences of international student migrants in Dublin by focusing on precarity and promise. We use Lorey's tripartite understanding of precarity (2015. States of Insecurity: Government of the Precarious. London: Verso) to show how international student migrants in Dublin experience legal precarisation, economic precarity and personal precariousness. This is, we argue, mitigated by promise (Ahmed 2010. The Promise of Happiness. Durham: Duke University Press), as international student migrants seek to navigate their way through precarity in place. The paper offers important insights into the complexity of international student migration, based on the lived experiences of migrants themselves.
