This qualitative study investigated academic challenges, supports and the role of readiness in academic adaptation of international students. 20 international students were recruited for data collection employing semi-structured interviews. The results showed that three types including academic challenges, socio-cultural challenges and language incompetency were affecting the academic adaptation process. In addition, three types of supports including university support, peer support and psychological motivation which helped international students cope with the challenges while readiness played a significant role in balancing challenges and supports. Pre-departure preparedness and on-campus orientation instilled readiness among international students. The study suggested that sending countries should make effective mechanism to prepare the students before their departure. It can include host country's language, its education system, degree requirement, culture, climate and food etc. The study proposed theoretical model of academic adaptation of international students for future quantitative research.
