U.S. International Student Numbers Hit a Record High. Why Was Academic Enrollment Nearly Flat?

Between 2023/24 and 2024/25, international undergraduate enrollment increased from 342,875 to 357,231, a gain of 4.2%. Graduate enrollment fell from 502,291 to 488,481, a decline of 2.7%, while non-degree enrollment decreased by 941 students. These changes almost completely offset one another, leaving the combined academic enrollment total virtually unchanged. But the underlying movements were significant: undergraduate enrollment recorded its first substantial recovery since the COVID-19 pandemic, while graduate enrollment declined after three consecutive years of growth.

A comparison with the pre-pandemic period puts these developments into perspective. In 2019/20, U.S. institutions enrolled 419,321 international undergraduates. By 2024/25, that population was still 62,090 students, or approximately 14.8%, below its earlier level. Graduate enrollment followed a different trajectory, rising from 374,435 in 2019/20 to 488,481 in 2024/25, an increase of 30.5%. The latest undergraduate growth therefore represents a recovery from a substantially reduced base, whereas the graduate decline follows several years of considerable expansion. Although the two groups moved in opposite directions in 2024/25, they occupied very different positions relative to the pre-pandemic market.

The national recovery also varied considerably by country of origin. While total international undergraduate enrollment grew by 4.2%, undergraduate enrollment from China fell from 87,551 to 78,583, a decline of 10.2%. This contrast shows that an improving overall undergraduate market does not necessarily mean that every major source market is recovering. Moreover, undergraduate programs, professionally oriented master's degrees, and research doctorates operate under different funding and educational models, meaning that similar enrollment changes can have different implications across institutions and programs.

OPT participation reached 294,253 in 2024/25, increasing by 21.2% from the previous year. OPT participants accounted for 25.0% of the total international student population reported by Open Doors, compared with 21.5% in 2023/24. The program allows eligible international students to undertake practical training related to their field of study, with qualifying STEM graduates able to apply for an extended period of authorization. As a result, the Open Doors total includes not only students currently enrolled in academic programs but also individuals participating in practical training after completing their studies.

Opportunities for professional development after graduation are an important part of the appeal of U.S. higher education. A 2024 survey of 1,252 Chinese graduate students in the United States, approximately 80% of whom were doctoral students, found that 73% planned to apply for OPT. Among respondents intending to return to China, 68% also planned to apply. Their plans suggest that pursuing post-study practical training and eventually returning home are not mutually exclusive.

Historically, OPT participation has not grown continuously. The number of participants stood at 223,539 in 2019/20 before falling to 184,759 in 2021/22. It subsequently recovered, with substantial increases in both 2023/24 and 2024/25. The earlier expansion of international graduate enrollment created a larger potential pool of students who could later enter OPT, while longer authorization periods under STEM OPT may also allow eligible participants to remain in the program for additional time.

The recent expansion, however, was not uniform across countries of origin. While total OPT participation increased by 21.2% in 2024/25, the number of Chinese participants rose only 0.7%, from 61,552 to 61,981. The nationwide surge therefore cannot be interpreted simply as evidence of a sharp increase in Chinese graduates' willingness to remain in the United States. Nor does a larger OPT population, by itself, establish that U.S. employers are hiring international graduates at a faster rate. The figures are better understood in the context of earlier enrollment cohorts, academic fields, and the duration of practical training opportunities.

While OPT participation expanded, the number of new international students entering U.S. institutions declined in fall 2024. Open Doors reported 277,118 new international students, down 21,587, or 7.2%, from 298,705 the previous year. The decline was concentrated at the graduate level: new graduate enrollment fell by approximately 15%, while new undergraduate enrollment increased by around 5%. In Open Doors reporting, new international students are those enrolling at the reporting institution for the first time, a category that can include transfer students rather than exclusively first-time arrivals in the United States.

These new enrollment figures reinforce the divergence already visible in the academic enrollment totals. Undergraduate enrollment increased, as did the number of new undergraduate students. Graduate education, by contrast, recorded declines in both measures. This is particularly notable given the substantial expansion of international graduate enrollment during the preceding three years: a large population of students from earlier entering cohorts continued to support overall graduate enrollment even as the number entering institutions in fall 2024 fell markedly.

Changes in new enrollment may become more visible in subsequent academic years as existing students graduate and new cohorts replace them. Total enrollment at any given time reflects students admitted over several years, so the effects of a smaller entering cohort need not appear immediately in the overall population. Their eventual impact will depend on program duration, graduation patterns, and the size of future entering classes.

Taken together, the 2024/25 figures suggest that international undergraduate education was beginning to recover from its pandemic-era contraction, while graduate education showed signs of adjustment following several years of expansion. At the same time, OPT participation continued to grow rapidly, pushing the broader international student total to a record high. These developments were occurring simultaneously, even though they pointed in different directions.

The record international student population in 2024/25 reflected a system encompassing both academic enrollment and practical training after study. Separating undergraduate, graduate, and OPT populations reveals a more differentiated market: undergraduate enrollment was recovering, graduate enrollment was beginning to adjust, and OPT participation was growing rapidly after an earlier decline.

The significance of international student growth lies not only in how many students are counted, but also in where that growth is occurring and which populations are driving it. Diverging undergraduate and graduate trends have implications for the scale and composition of academic programs, while changes in incoming cohorts provide an additional indication of how future enrollment may evolve.

The record total remains an important milestone. But the contrasting movements beneath it offer a more revealing picture of the U.S. international education market in 2024/25.
