This article provides an introduction to the themed section "Linguistic Justice, Migration and the Nation-State." First, it illustrates the rationale for the themed section by examining the relationship between language, migration and the nation-state. It argues that accounts of linguistic justice that fail to incorporate, discuss and understand the language interests of migrants, and the potential tensions that may emerge between migrants' linguistic rights and duties, and between their linguistic rights and those of autochthonous groups, are likely to become obsolete in an increasingly mobile world. Second, it provides an overview of the articles in the themed section. And, finally, it highlights four specific areas of inquiry that should deserve greater attention in future scholarship.
