This study investigates the effects of using open social VR for university English as a foreign language (EFL) learners' intercultural communication learning. The project involved two stages: (1) carefully designed activities for students to practice different language-learning tasks with their peers; (2) implemented in an open social VR environment for intercultural interactions. Data from multiple sources, including surveys, video-recordings, and oral reports, were collected and analyzed. Findings reveal that the participants perceived the social and physical presences afforded by the VR environment positively. Occurrences of intercultural communicative competence were identified in the participants' interactions with international interlocutors in open social VR spaces. Whereas the participants were doubtful of the effectiveness of the approach when practicing language tasks with their peers, they greatly enjoyed the interactions with international interlocutors via the VR technologies in the digital wild context, i.e., applying the resources outside of the classroom setting. Based on the findings of this study, focuses and directions for future research are discussed and suggested.
