Sixteen percent of all high-impact, high-tech companies include at least one immigrant, according to a new report by the Center for Technology Innovation at Brookings. They survey and consequent case studies found significant trends among immigrant entrepreneurs in the high-tech field. Respondents were found to be heavily rooted in the U.S. — 77 percent of them have become American citizens and almost 75 percent have lived in the U.S. for more than 15 years. In comparison to their domestic peers, immigrant entrepreneurs have much higher educational achievement (almost twice as likely to hold a doctoral degree). These individuals have a similar amount of work experience to their successful domestic counterparts (roughly 10 years). Finally, the number of immigrant entrepreneurs is roughly equal to the total immigrant population (13 percent). However, since 1990 the number of immigrants with a bachelors degree or above in a STEM related field has increased significantly.
