International graduate students are coming in ever-growing numbers to English-speaking countries. Educators have long believed that the successful English-learning experience of these students in their home countries will naturally lead to success in their academic studies and social life abroad.

Based on a supportive sociocultural theory of second-language acquisition, the article provides recommendations for assisting international graduate students, especially those from East Asia, to enhance their academic performance and quality of life in Canada.
