Living in Indonesia as part of an immersion program, Bahasa Indonesia untuk Pembelajar Asing (BIPA/Education of Bahasa Indonesia for Foreigners) learners are inevitably involved in communicating with local communities, including getting to know new individuals. Small talk is a tool to start conversations and build relationships during these meetings. However, BIPA students often experience culture shock when small talk questions or expressions that do not match their cultural background arise. This research aims to describe (1) polite small talk expressions, (2) impolite or strange small talk expressions, and (3) responses elicited by inappropriate small talk expressions. A qualitative approach was used for this research, and data was collected through questionnaires completed by fifteen BIPA students participating in an immersion program in Indonesia. The findings in this research are integrated with Hall's intercultural communication theory (1976). The findings reveal that (1) BIPA students perceive polite small talk expressions as greetings and questions that are commonly used to start a conversation, (2) small talk expressions that are considered impolite or unusual by BIPA students often involve questions related to privacy that cause discomfort and (3) BIPA learners' responses to impolite small talk vary between aggressive actions and acquiescence, depending on their respective cultural backgrounds.
