UC San Diego’s international enrollment rises as national new-student numbers fall amid visa uncertainty

A local outlier in a shifting national pattern

UC San Diego reported growth in its international student presence even as national indicators show fewer new international students arriving at U.S. campuses. The contrast highlights how a large research university in San Diego is navigating a national environment marked by visa delays, heightened scrutiny and uneven enrollment by academic level.

At the start of the 2025–26 academic year, UC San Diego had 8,134 international students, representing about 18.6% of its campus population. That figure is higher than many peer institutions’ shares and positions the campus as one of the region’s most internationally concentrated universities.

National totals up, but new enrollment and graduate trends soften

Across the United States, colleges and universities hosted 1,177,766 international students in the 2024–25 academic year, a 5% increase from the prior year. International students represented about 6% of overall U.S. higher education enrollment. However, the number of new international students enrolling for the first time in fall 2024 declined 7% nationally, an early sign of slowing momentum even amid higher overall totals.

More recent institutional reporting suggests additional softness. A fall 2025 snapshot based on participating campuses showed a 17% drop in new international enrollments, alongside a 1% decline in total international student counts. The same snapshot indicated a split by level: undergraduate enrollment increased while graduate enrollment declined sharply. Open Doors 2025 data similarly showed graduate international enrollment decreased by 3% in 2024–25 after several years of growth, while undergraduate international enrollment increased 4%.

What may explain UC San Diego’s increase

One factor behind UC San Diego’s rise is a strategy used by some universities facing uncertainty in international yield: expanding the number of admission offers to stabilize enrollment. With national commencements declining, campuses that can convert offers into arrivals may post year-over-year gains even as the national pipeline tightens.

At UC San Diego, the international population is large enough to affect campus operations and finances. International students typically pay higher tuition than California residents, which can make fluctuations in international enrollment materially significant for public universities.

Regional context: mixed results in San Diego County

San Diego State University reported a decrease in international enrollment, falling from 957 to 889 students, with visa processing delays and appointment availability cited as key obstacles. The diverging outcomes between major San Diego-area institutions underline how sensitive international enrollment can be to administrative timing, program mix, and the ability to support students through visa and arrival logistics.

Key numbers at a glance

• UC San Diego international students (start of 2025–26): 8,134 (about 18.6% of campus population)
• U.S. international students total (2024–25): 1,177,766
• New international students (fall 2024): down 7% nationally
• Fall 2025 snapshot: new international enrollments down 17%; undergraduate up, graduate down

The national picture shows overall international student totals remaining high, while the newest cohort—especially at the graduate level—has become more volatile.

For UC San Diego and other research-intensive campuses, the next test will be whether increases can be sustained if new international commencements remain below recent peaks and graduate enrollments continue to soften nationwide.
