National Union of Students–Union of Students in Ireland

NUS-USI, the student movement in Northern Ireland, was formed in 1972 by bilateral agreement between the National Union of Students of the United Kingdom (NUS) and Aontas na Mac Léinn in Éirinn (AMLÉ, formerly USI, the Union of Students in Ireland) to address the particular problems of representing students in Northern Ireland. As of 2018, NUS-USI represented approximately 200,000 students in the region.
