The sharp decline in international student enrollment at US universities is emerging as more than a challenge for higher education. New economic research suggests it could gradually erode the country’s long-term competitiveness by reducing the supply of highly skilled graduates who fuel innovation, entrepreneurship and advanced industries.
A study released by the Peterson Institute for International Economics estimates that if the number of international STEM graduates trained in the United States falls by one-third over the next decade, the country’s gross domestic product could ultimately be between $240bn and $481bn lower than it otherwise would have been. The findings highlight how international student enrollment has become closely tied to the future of America’s technology and research sectors.
Universities feel the impact as enrollment falls
US colleges have already begun experiencing the financial consequences. According to NAFSA, international student enrollment declined by 17% during the last academic year. That reduction translated into approximately $1.1bn in lost tuition-related economic activity and nearly 23,000 fewer jobs supported by international education.
The decline follows a series of immigration policy changes introduced during President Donald Trump’s second administration. Alongside broader immigration restrictions, the administration tightened rules affecting international students and graduates seeking employment after completing their studies.
The administration also introduced significant changes to the H-1B visa programme, increasing employer application costs from roughly $5,000 to $100,000 per application before a federal judge blocked the policy earlier this month. The White House has indicated it plans to appeal that ruling.
Researchers argue these changes matter because universities have become the primary route through which highly skilled international workers enter the US labour market. Many graduates later transition into specialist employment through work visa programmes after completing master’s or doctoral degrees.
The Peterson Institute researchers wrote: “A major and enduring economic advantage of the United States has been its ability to recruit and educate top talent from around the world.”
Why STEM graduates matter to long-term growth
International students are especially concentrated in science, technology, engineering and mathematics programmes. According to the Institute of International Education, 57% of international students enrolled in US institutions last year were studying STEM subjects.
Their presence becomes even more significant at advanced qualification levels. The Peterson Institute found international professionals account for 42.1% of STEM workers holding master’s degrees and nearly half of those with doctorates. Between 2000 and 2023, more than 60% of new PhD-qualified STEM workers entering the workforce were foreign-born.
Many of these graduates remain in the United States for years after finishing their studies. Researchers estimate almost 40% continue living and working in the country more than eight years after graduation, creating a steady pipeline of engineers, researchers and entrepreneurs for American employers.
That talent has played an important role in business creation. A report published this month by the National Foundation for American Policy found immigrants have founded or co-founded 59% of US startups valued at more than $1bn. Separate research published by Stanford economists in 2023 concluded immigrants contributed to 23% of US patents issued over recent decades.
Beyond university finances, this reflects a broader global competition for highly skilled workers. The Organisation for Economic Co-operation and Development has repeatedly highlighted that advanced economies increasingly compete for STEM talent because innovation-led industries contribute disproportionately to productivity growth. Countries that combine strong universities with favourable immigration pathways have generally strengthened their position in sectors such as artificial intelligence, biotechnology and advanced manufacturing.
Global competition for talent is intensifying
The Peterson Institute cautions that talent discouraged from studying in the United States is unlikely to disappear from the global workforce. Instead, those students are expected to pursue education and careers elsewhere.
Recent NAFSA data suggests universities across Asia and Europe are already attracting larger numbers of international undergraduates while many US institutions continue facing enrollment pressures. Universities in Hong Kong and Japan have also stepped up recruitment efforts targeting students who may have reconsidered studying in America.
Future enrollment figures, visa policies and legal challenges surrounding immigration rules will determine whether the recent decline proves temporary or develops into a longer-term shift in global talent flows. For businesses dependent on advanced technical expertise, those trends could become as important as any labour market or economic indicator.
