In this article the author analyses the communicative demands placed on migrants navigating immigration law in a fast-moving policy environment and implications for adult migrant language education. Data are from an ethnographic study of a lawyer, Lucy, and her clients at a legal advice service in Leeds, England, and include interviews and recordings of lawyer-client interactions. The analytical focus is on Lucy's stance (Jaffe, 2009b), on how she presents herself as an ally of her multilingual clients, and on the stance-marking strategies she and her clients use as they strive to make meaning. The study took place in 2016, a time of volatility for the policies that impinge on immigration law and on legal interaction for migrants: the upsurge of right-wing populist movements in Europe, erratic positions on migration in the United States, and the referendum that decided the United Kingdom would leave the European Union. The author maintains that the link is rarely drawn between interaction in legal and other institutional settings and the content of language classes designed to aid adult migrant settlement, and argues for an approach to adult migrant language education that critically addresses this point.
