On the other hand, 85 percent of engineering doctoral degree holders are likely to initially go into business or the industry sector. Under the circumstances, providing doctoral students as well as postdoctoral researchers with necessary skills for nonacademic positions has become one of the important roles for graduate schools and institutions. The America COMPETES Act recognized the importance of graduate student support for obtaining skills needed when they pursue nonacademic careers, and required National Science Foundation (NSF) to increase or decrease funding for the Integrative Graduate Education and Research Traineeship (IGERT) programs at least at the same rate as it increases or decreases funding for the Graduate Research Fellowship. There are no comprehensive data of international postdoctoral researchers in the US because of the less-organized survey and the difficulty in counting international postdoctoral researchers. The proportion of postdoctoral researchers on temporary visas reached 53.6% in 2010. The life sciences hold the largest percentage of postdoctoral researchers on temporary visas; in 2008, approximately 56% of postdoctoral researchers in the life sciences were temporary residents. Of these postdoctoral researchers on temporary visas, four out of five earned their PhD outside of the United States. There exists fear that foreign PhD's are taking postdoctoral research positions from American researchers. The influx of foreign PhD's has influenced the supply of ready-researchers, and thereby, the wages. One estimate claims that a 10% increase in the supply of foreign postdoctoral researchers lower the position salary by 3 to 4%.
