This study examines how cultural background shapes the communication styles of EFL students at UIN Ar-Raniry Banda Aceh. Communication in EFL learning is influenced not only by linguistic ability but also by cultural values such as collectivism, politeness, respect for hierarchy, and high-context communication. Using a descriptive qualitative design, data were collected through semi-structured interviews with eight students and analyzed through thematic analysis. Findings show that students’ cultural orientations significantly affect their verbal and non-verbal communication. Many students prefer indirect expression, avoid confrontation, rely on silence and gestures, and show hesitation when interacting with lecturers due to cultural expectations of respect. Cultural differences also create barriers, including fear of making mistakes, reluctance to speak, and misunderstandings in classroom interaction. The study concludes that cultural background plays a crucial role in shaping students’ communication styles and participation in EFL learning. It highlights the need for culturally responsive teaching strategies to support more inclusive and effective communication in the classroom
