NSF Survey of Graduate Students and Postdoctorates, 2024
Who holds the postdoc jobs
A postdoctoral appointment is the job an American doctorate leads to. It is the step between the degree and a faculty position or a research career, and roughly half of these posts are paid for with federal research money.
This page counts them by citizenship. A postdoc is counted as American here if they are a citizen or a permanent resident. Everyone else holds a temporary visa.

Americans are a minority of the postdoctoral workforce
Not at nine universities. Nationally.
58.3% of postdoctoral appointees in the United States hold a temporary visa. American citizens and permanent residents are 41.7% — a minority of the people doing postdoctoral research in their own country, in a workforce where about half the posts are paid for by the federal government.
This is the measured finding. What follows is what it means for the nine universities named in October.
The nine named universities
On 8 October 2026 the Department of Labor and the Department of Justice announced an investigation into J-1 visa use at nine universities, and said that about 61% of postdoctoral researchers and federally funded workers at those institutions are foreign nationals, against a national average of 38%.
The first figure checks out. Computed from the NSF survey, the nine come to 60.7%: 8,545 of 14,080 postdocs on a temporary visa.
The second figure does not match this survey. The national average on the same measure is 58.3%, not 38%. The two numbers count different things, and the difference decides what the story is.

The nine are not outliers. They are typical. They sit about 2.4 points above a national figure that is already over half.
That is the larger finding. If these nine were far above a low national average, this would be a story about nine universities and an enforcement action would address it. They are not. On this measure the American postdoctoral workforce is a minority of itself everywhere, and the nine named institutions look much like the rest of the country.
| Institution | Postdocs | Temporary visa | American | Share foreign |
|---|---|---|---|---|
| Yale University | 1,458 | 1,015 | 443 | 69.6% |
| Massachusetts Institute of Technology | 1,452 | 988 | 464 | 68.0% |
| California Institute of Technology | 574 | 388 | 186 | 67.6% |
| Stanford University | 2,645 | 1,723 | 922 | 65.1% |
| University of California, Davis | 679 | 441 | 238 | 64.9% |
| Arizona State University | 311 | 193 | 118 | 62.1% |
| University of Pittsburgh | 826 | 482 | 344 | 58.4% |
| Harvard University | 5,813 | 3,142 | 2,671 | 54.1% |
| Brown University | 322 | 173 | 149 | 53.7% |
| The nine together | 14,080 | 8,545 | 5,535 | 60.7% |
| Every institution surveyed | 69,877 | 40,746 | 29,131 | 58.3% |
Institutions are matched on their federal UNITID, not on their name. The investigation was announced on 8 October 2026. This page reports that it was announced and what the survey counts. It makes no claim that any institution broke a law.
The institutions with the highest shares
Every institution reporting at least 50 postdocs, ranked by the share holding a temporary visa. The nine named universities are shown in bold where they appear.
175 institutions clear the floor of 50 postdocs. A unit with nine postdocs and six on a visa is 67% and tells a reader nothing, which is why the floor exists.
Who pays for the posts
48.1% of postdoctoral appointments are federally supported — 33,582 posts.
| Federal source | Postdocs supported |
|---|---|
| NIH | 19,413 |
| NSF | 3,913 |
| Defense | 2,452 |
| Energy | 2,245 |
| Agriculture | 1,166 |
| HHS | 1,037 |
| NASA | 701 |
The survey reports how many postdocs are federally supported and how many hold a temporary visa. It does not report how many are both, so these two figures cannot be multiplied. A page that multiplied them would be inventing a number the survey does not contain.
Method and limits
What this counts, and what it cannot.
- A postdoc counted as foreign holds a temporary visa. US citizens and permanent residents are counted as American.
- The survey reports how many postdocs are federally supported and how many are foreign. It does not report how many are both, so the two figures cannot be multiplied.
- Figures are summed from organisational units to the institution. A single GSS row is a school or department, not a university.
- This counts postdoctoral appointees. Graduate students are a different population and are measured separately.
