More than one million skilled immigrant workers—including Indian and Chinese scientists and engineers—and their families are competing for 120,000 permanent U.S. resident visas each year. This sizeable imbalance is likely to fuel a "reverse brain-drain" with skilled workers returning to their home countries, according to a new report from researchers at Duke and other universities released Wednesday by the Ewing Marion Kauffman Foundation.
The situation is even bleaker as the number of employment visas issued to immigrants from any single country is less than 10,000 per year, with a wait time of several years.
The United States benefits from having foreign-born innovators create their ideas in this country," said Vivek Wadhwa, executive in residence at Duke's Pratt School of Engineering and Wertheim Fellow with the Harvard Law School. "Their departures would be detrimental to U.S. economic well-being. When foreigners come to the United States, collaborate with Americans in developing and patenting new ideas, and employ those ideas in business in ways they could not readily do in their home countries, the world benefits."
Conducted by researchers at Duke, New York University and Harvard University, the study is the third in a series that focuses on immigrants' contributions to the competitiveness of the U.S. economy. Earlier research revealed a dramatic increase in the contributions of foreign nationals to U.S. intellectual property over an eight-year period.
In this study, "Intellectual Property, the Immigration Backlog, and a Reverse Brain-Drain," researchers offer a more refined measure of this rise in contributions of foreign nationals to U.S. intellectual property and analyze the possible impact of the immigrant-visa backlog for skilled workers. The key finding from this research is that the number of skilled workers waiting for visas is significantly larger than the number that can be admitted to the United States. This imbalance creates the potential for a sizeable reverse brain-drain from the U.S. to the skilled workers' home countries.
These findings are important, highlighting the invaluable contribution of foreign nationals to our country's technological and economic vitality," said Duke Provost Peter Lange, the university's top academic officer. "We know from our own experience here that students from China, India and other nations can play an outstanding role in advancing knowledge and creating new jobs, especially in cutting-edge fields."
The earlier studies, "America's New Immigrant Entrepreneurs" and "Entrepreneurship, Education and Immigration: America's New Immigrant Entrepreneurs, Part II," documented that one in four engineering and technology companies founded between 1995 and 2005 had an immigrant founder. Researchers found these companies employed 450,000 workers and generated $52 billion in revenue in 2006. Indian immigrants founded more companies than the next four groups (from the United Kingdom, China, Taiwan and Japan) combined.
Furthermore, these companies' founders tended to be highly educated in science, technology, math and engineering-related disciplines, with 96 percent holding bachelor's degrees and 75 percent holding master's or Ph.D. degrees.
The analysis of the World Intellectual Property Organization database in this earlier work revealed the percentage of foreign nationals contributing to U.S. international patent applications increased from an estimated 7.3 percent in 1998 to 24.2 percent in 2006. The largest foreign-born group was from China (mainland and Taiwan). Indian nationals were second, followed by Canadian and British nationals.
Among key findings in the most recent report:
- Foreign nationals residing in the U.S. were named as inventors or co-inventors in 25.6 percent of international patent applications filed from the U.S. in 2006. This represents an increase from 7.6 percent in 1998.
- Foreign nationals contributed to more than half of the international patents filed by a number of large, multi-national companies, including Qualcomm (72 percent), Merck & Co. (65 percent), General Electric (64 percent), Siemens (63 percent) and Cisco (60 percent). Forty-one percent of the patents filed by the U.S. government had foreign nationals as inventors or co-inventors.
- In 2006, 16.8 percent of international patent applications from the U.S. had an inventor or co-inventor with a Chinese-heritage name, representing an increase from 11.2 percent in 1998. The contribution of inventors with Indian-heritage names increased to 13.7 percent from 9.5 percent in the same period.
- The total number of principals in the employment-based categories and their family members waiting for legal permanent residence in the U.S. in 2006 was estimated at 1,055,084. Additionally, there are an estimated 126,421 residents abroad also waiting for employment-based U.S. legal permanent residence, adding up to a worldwide total of 1,181,505.
Using data from the New Immigrant Survey, the authors found that in 2003 about one in five new legal immigrants in the U.S. and about one in three employment-based new legal immigrants either planned to leave the U.S. or were uncertain about remaining. The authors had no data on how many foreign nationals have actually returned to their homelands.
Given that the U.S. comparative advantage in the global economy is in creating knowledge and applying it to business, it behooves the country to consider how we might adjust policies to reduce the immigration backlog, encourage innovative foreign minds to remain in the country and entice new innovators to come," said Robert Litan, vice president of research and policy at the Kauffman Foundation.
