The results showed that the role of host families contributed effectively to improve the linguistic and cultural competencies of non-Arabic-speaking students in the Sultanate of Oman, allowing the student to contact the surrounding community and learn the language in a wider environment. Cultural competence came in the first rank, as it received the highest arithmetic mean of (4.42), a standard deviation of (0.31) and a very high degree.
