There are over 700,000 international students currently studying in the U.S. (McMurtrie, 2011) contributing close to $12 billion yearly to the U.S. economy (Altbach, 2004). Universities cannot take for granted that international students will choose U.S. institutions. While great attention and research efforts have been given to support programs like international student orientation, there is a gap in the literature examining support programs within residence halls targeting international students. The purpose of this quantitative study was to evaluate an international roommate program (IRP) to determine its impact on international students at a large state school in the Northeast. This research addressed the question: Does participation in an international/domestic roommate-pairing program have a positive impact on international students' satisfaction, acclimation, academic success, navigation of the English language, and social relationships? This research question was addressed by surveying first-year international students living in residence halls and comparing outcomes of those participating in one of the IRP programs (IRP1 and IRP2) with those not participating (NON). Using the statistical method of Factor Analysis for data reduction of survey responses, eight variables were created based on themes addressing the primary research question. These eight newly created variables were analyzed through ANCOVA (statistically controlling for 16 demographic variables). The results showed differences between IRP1, IRP2, and NON groups through three key findings that were statistically significant: 1) IRP2 participants were more likely than NON participants to recommend the university others based on their residential experience; 2) IRP2 participants had greater overall satisfaction, acclimation, food satisfaction, and perceived benefit from having an American roommate than IRP1 participants; 3) IRP1 participants had lower food satisfaction than the IRP2 and NON participants. Residential environment (living accommodations and dining) and structured support appeared to have the greatest impact on international students. The findings of this study support the hypothesis that the program indeed had positive impacts and will contribute important information to the existing literature base and can be used by Residence Life professionals to establish effective support programs for international students within the residence halls.
