First-Year Writing (fyw) courses are ideal writing spaces where students' diverse identities and language resources can flourish for specific rhetorical purposes. While research has focused on multilingual students' language and writing practices, little attention has focused on self-identified multilingual students' perceptions of language difference in fyw. Because fyw courses are an integral space in students' writing experiences and an ideal place to counter English-only ideologies, this article focuses on self-identified multilingual students' perceptions of how they negotiate language practices in academic contexts in higher education and how they perceive the role of languages other than English in fyw. Self-identified multilingual students' perceptions of language difference can inform pedagogical practices in fyw that align with students' identities as linguistically diverse writers.
