How US Science and Engineering Depends on Immigrants

Summary:
Every other year, the National Science Foundation is required to publish a "Science and Engineering Indicators" report. For the January 2020 version, the NSF went with a summary report, called "The State of U.S. Science & Engineering 2020," which is then accompanied by seven more detailed reports. Here, I'll focus on some evidence from the overview report on the subject of how the US science and engineering workforce depends on immigrants, both as worker and also as students in its higher education system. Foreign-born workers—ranging from long-term U.S. residents with strong roots in the United States to more recent immigrants—account for 30% of workers in S&E occupations. The number and proportion of the S&E workforce that are foreign born has grown. In many of the broad

Foreign-born workers—ranging from long-term U.S. residents with strong roots in the United States to more recent immigrants—account for 30% of workers in S&E occupations. The number and proportion of the S&E workforce that are foreign born has grown. In many of the broad S&E occupational categories, the higher the degree level, the greater the proportion of the workforce who are foreign born. More than one-half of doctorate holders in engineering and in computer science and mathematics occupations are foreign born (Figure 9).

Within the US higher education system, a disproportionate number of the science and engineering degrees go to immigrants--many of whom then remain in the US economy at least for a time

In the United States, a substantial proportion of S&E doctoral degrees are conferred to international students with temporary visas. In 2017, temporary visa holders earned one-third (34%) of S&E doctoral degrees, a relatively stable proportion over time. They account for half or more of the doctoral degrees awarded in engineering, mathematics and computer sciences, and economics. Three Asian countries—China, India, and South Korea—are the largest source countries and accounted for just over half (54%) of all international recipients of U.S. S&E research doctoral degrees since 2000. By comparison, students on temporary visas earn a smaller share (6% in 2017) of S&E bachelor’s degrees. However, the number of these students has more than doubled over the past 10 years.
A majority of the S&E doctorate recipients with temporary visas—ranging between 64% and 71% between 2003 and 2017—stayed in the United States five years after obtaining their degree. Those from China and India, however, saw a decline in their respective “stay rates” from 93% and 90%, respectively, in 2003 to 84% and 85%, respectively, in 2013; the rates remained stable from 2013 through 2017. The stay rate increased for those from South Korea (from 36% in 2003 to 57% in 2017). Stay rates also vary by field of doctoral degree. Among S&E doctorate recipients, social sciences (52%) has a lower stay rate than the average across all fields (71% in 2017).
I know that we live in times of substantial concern about how technology may be transferred from the United States to other countries. Whatever one's concerns in that area, there is also another side to consider, which is that in raw numerical terms the US has a heavy dependence on imported science and engineering workers and American universities in science and engineering fields maintain their status and preeminence thank in substantial part to their foreign students. 

The NSF report also points out that when it comes to sheer numbers of science and engineering degrees, the dominant position of the US and European economies is eroding. For example, here are the trends in the number of university degrees  given in science and engineering. That rising purple line is the total for China, taking off. Concerns are sometimes raised that a number of these degrees in China may not represent especially high quality achievement in learning. But the sheer numbers are nonetheless striking--and the quality does seem to be improving over time.

A similar if less vivid trend is apparent in granting of doctoral degrees in science and engineering fields. Here, the large EU economies have a lead compared to the US, with China and India rising rapidly

The economic competitiveness of nations is built to a substantial extent on the talents of their workforce.  It seems likely that future economic growth for the US and other advanced economies will depend heavily on the industries built on advances in science and engineering. One of the great competitive advantages for the US economy has been that its education system, economy, and society are attractive and open to so many workers and students from around the world with skills in these areas.
