A great deal of research has recognized the necessity of receiving proper predeparture training for being able to truly benefit from international internship experiences. However, few researchers have taken the next step by exploring how domestic programs could pedagogically and psychologically prepare students for their professional experiences abroad. This study examines the role that a language-for-specific-purposes course plays in the process of preparing students for their upcoming internship experiences in the target culture, with a focus on intercultural negotiation. The findings suggest the students were able to successfully develop the cultural awareness and communicative skills necessary to engage in the negotiation of cultural boundaries. Furthermore, the study discusses how the introduction of a role model, in-depth workplace scenarios, and creating a holistic view of one's learning experiences are the three pedagogical elements that contribute to the construction of a professional L2 self.
