|Abstract:||International students are valuable to domestic universities as they inspire intercultural learning, foster understanding of diversity and global issues, and contribute financially to the US economy. Although international students benefit universities, they encounter adjustment difficulties that differ from those of domestic students, such as language barriers, cultural differences, and academic adjustments. Little research exists on this subject; therefore, the challenges of international students are often overlooked by universities. Through qualitative and quantitative analysis, this study identifies the challenges that engineering international students experience. A survey and group interviews were conducted with first-year engineering students to identify the adjustment factors. While the domestic and international students identified similar adjustment issues, international students had more difficulty with making American friends, understanding cultural references, adapting to American food, and getting acquainted with unfamiliar teaching methods and assignments. This study will increase awareness about the adjustment factors that international students face so that universities will better help them succeed.
