Due to the significant value international students add to the U.S. higher education system, there is a need to better understand international students' challenges and barriers, as well as the support services offered to this population of students. Upon arrival to the country, many international students go through an overwhelming transition process while trying to adapt to a new academic system and a new culture. Some of the challenges researchers have identified for international students are language barrier, cultural shock, financial stress, and homesickness. However, many students choose to pursue post-secondary education in the United States because of the desire to pursue a higher standard of living, quality education, better job opportunities, and personal advancement. International students account for 4.6% of all college student populations in the United States. This study examined the challenges and barriers faced by international students, as well as the support services offered to them at colleges and universities. Additionally, immigration policies affecting international students are discussed. Lastly, acculturation, sense of belonging, and Schlossberg's Transition theory are considered in relation to international students' experiences. The overarching research question that guided this study was: "what support services offered by higher education institutions within the University of Louisiana System assist international students in successfully adapting to college?"
