The purpose of this study was to investigate English language related difficulties experienced by 30 Turkish dual diploma students studying in an ELT (English Language Teaching) program established between a Turkish and an American university, and to see the effects of those difficulties on the students' adjustment process in the U.S.A. The data of the study were collected through a 60-item questionnaire designed by the researcher and analyzed by using multiple regression analysis, paired-samples t-test, independent-samples t-test, and correlation coefficients. The results of the study indicated that students of this program experience English related difficulties at a moderate level; they experience more English related difficulties in their academic life as compared to their social life; and writing and speaking in academic settings are the most problematic skills for them.
