A common challenge for most students in intercultural contexts both in their academic studies and future careers is balancing speaking opportunities for talkative and less talkative students. The differences in individuals’ communication styles due to their backgrounds may lead to some concerns about intercultural competencies. In this respect, this study intends to explore the possible relationship between students' confidence in communication levels, their self-perception of English proficiency levels, and cultural styles. For this purpose, three questionnaires were carried out by the participation of 106 students at a state university. The obtained data were analyzed by conducting ANOVA tests. The findings indicated that participants have low to medium levels of English proficiency and as their language levels increase, their cultural self-awareness and cross-cultural communication levels increase as well. In addition, there is a significant relationship between their levels of confidence in communication and having outgoing personalities.
