Analysts warn that curbing international graduates in science, technology, engineering, and mathematics by as little as a third could shave roughly 0.7 percent to 1.3 percent off the United States’ economic output over the next ten years, a drop that would be as large as wiping out the entire GDP of Utah or South Carolina.
There are many ways to gauge a nation’s vitality. Gross domestic product growth is one common metric, and so is overall productivity. Yet there is another, less conventional yardstick that deserves attention: are the planet’s most gifted and ambitious people choosing to move here?
For much of American history, the answer has consistently been yes. Researchers, engineers, entrepreneurs, artists, and go-getters from across the globe have sought the United States because they believed they could build, discover, or launch ventures here while pursuing a more prosperous life.
We should be concerned about the day when that belief no longer holds true.
Regrettably, the Trump administration appears intent on bringing that day forward. Its aggressive tilt toward protectionism targets more than just foreign goods and capital; it also affects high-demand foreign talent.
Take, for example, a rule finalized in early July that substitutes fixed admission periods for the longstanding idea of “duration of status” for international students, exchange visitors, and foreign journalists. In practical terms, this means international students must secure government permission to remain beyond four years, even when their programs would take longer to complete. It also tightens opportunities for international graduates of American universities to stay and work afterward through the Optional Practical Training program.
A recent brief by Amy Nice, Michael Clemens, and Jeremy Neufeld of the Peterson Institute for International Economics underscores what is at stake. The authors map the pipeline by which international students—especially those in science, technology, engineering, and mathematics—enter American colleges and, ultimately, join the U.S. workforce. That pipeline is incredibly valuable for everyone.
The researchers show that the U.S. science and technology workforce relies heavily on foreign-born talent. Immigrants fill nearly one in three advanced STEM roles and close to half of positions that require a doctoral degree. Individuals who first arrived as students account for about one-fifth of degree-holding STEM workers and more than one-third of those with a Ph.D.
Clemens notes that STEM graduates who remain in the United States after finishing their studies patent new inventions at four times the rate of typical college graduates and account for roughly 10 percent of all new U.S. patents. They also launch high-growth startups at six times the rate of graduates born in America.
In other words, the idea that hiring a foreign engineer inherently costs an American engineer a job is a fallacy. Protectionism aimed at human capital rests on the same faulty logic as other forms of protectionism: the notion that the economy is a single pie and that inviting foreigners to participate reduces the share available to natives.
But economies do not operate that way. Talented people do not merely fill existing roles; they create opportunities by inventing products, starting companies, conducting research, and elevating the productivity of their colleagues. In the process, they generate chances for others that would not have existed otherwise.
Waving off foreign students is especially ludicrous in light of Washington’s fixation on outpacing China. Lawmakers insist that America is engaged in a life-or-death technological race, pouring billions into subsidies for semiconductors and other strategic sectors. They craft elaborate industrial policies to keep America at the forefront of artificial intelligence, quantum computing, and advanced manufacturing.
And then, when a brilliant young scientist from India, China, or another country earns an advanced degree at an American university and wishes to stay and contribute, our government suggests perhaps they should leave.
You can invest billions of taxpayer dollars in a semiconductor plant in Arizona. You cannot manufacture genius via an appropriations bill.
The Peterson Institute team estimates that deterring as little as a third of international STEM graduates could shrink the American economy by between 0.7 percent and 1.3 percent, translating to roughly $200 billion to $400 billion in GDP over ten years—equivalent to losing the entire economies of Utah or South Carolina.
These projections rest on assumptions about future immigration and productivity, but the central message is clear: when capable people depart or never arrive, we forgo their ideas, businesses, innovations, and all the economic activity that flows from them.
There is also something more profound at stake. One of the nation’s greatest strengths is that people choose to come here with their feet. They leave familiar places—sometimes crossing thousands of miles—because they glimpse opportunities unavailable elsewhere. That choice is a powerful vote of confidence in American institutions: in our markets, our rule of law, and our culture of entrepreneurship. We should never take it for granted.
Indeed, the prospect that the world’s brightest young minds might conclude that pursuing a future here is no longer worthwhile should alarm us—not just because we would forfeit their economic contributions, but because their decision would reveal something fundamental about the state of the country.
