This study reports findings of an analysis of the citation practices of L2 undergraduate students in the context of first-year writing (FYW). Data consist of a corpus of 100 source-based research papers written by L2 students in a FYW course. Taking a multi-perspective analytical approach, we examine L2 undergraduate students' citation practices in terms of surface forms, rhetorical functions, and writer stance. Results indicate that L2 students use a restricted range of reporting structures, and they primarily use sources for attribution function to display their knowledge of the topics. Furthermore, as opposed to taking a strong positive or negative position, the findings show that L2 student writers mainly adopt a non-committal stance by merely acknowledging or distancing themselves from cited materials, suggesting that L2 students are inclined to show deference to the perceived authority of published sources. We conclude with pedagogical options for enhancing L2 university students' citation practices.
