This book explores how international students construct target language- (TL-) mediated social spaces for socializing. It asks what factors either prevent or promote the construction of TL-mediated socializing opportunities by international students, how such students can grow both as TL learners/speakers/users and as people throughout their TL-mediated socializing, and how international students’ socializing, and their affective states during socializing, change across time during their stay in the host country.
