From 1978 to 2008, almost 1.4 million Chinese students have benefited from China's "open door (to the West) policy" and have entered the U.S. and other Western societies since the 1980s. This group of scholars truly crossed the globe and brought with them diversity of culture from the East to the West. Among the Chinese professional group, the Chinese petroleum professionals have led the way for this movement. The purpose of this study was to meet cross-cultural research needs in global business and leadership development. In particular, the study focused on a group of Chinese petroleum professionals who grew up in mainland China, were educated first in China (undergraduate level), immigrated to U.S., achieved higher education in the U.S. (graduate level), and have been integrated into U.S. society. This group of scholar-practitioners play important roles in their organizations, not only through technical expertise, but by also understanding first-hand the cultural impacts of globalization in the oil industry and the other organizations. This study focused on cultural and leadership behavior preferences of the study group and compared the global leadership preferences of this group against the reported Chinese culture and leadership scores in the GLOBE study. This research found significant differences between the two groups, and it further demonstrated differences between the study group's scores and the GLOBE study scores for the China, U.S., Taiwan, and Hong Kong.
