This paper examines the roles of different language ideologies--sets of common-sense beliefs about language and its speakers--in students' identity construction and negotiation in the context of internationalizing higher education. Along with the increasing diversity of students as English speakers, language ideologies have been critically examined for potential contribution to inequalities among students. I analyze two focus group discussions of students from international English-medium instruction master's programs at a Finnish university. I explore the students' talk using critical discursive psychology to illuminate possible intersections between language ideologies and students' situated identity construction, paying attention to ideological dilemmas alongside students' identity negotiation. The findings indicate that both emerging and established language ideologies may become relevant to students' identity construction and negotiation. Possibly, turning students' attention towards the multilinguality of every student and the specific purposes and characteristics of academic language might contribute to the discursive sustainability of inclusive interpersonal relationships among students.
