Alarm as US mulls prioritising citizens in research funding
A senior White House official said the Trump administration is considering ways to prioritise research funding to American citizens, triggering alarm in the research community that the country could destroy its century-long status as a magnet for overseas talent.Michael Kratsios, director of the White House Office of Science and Technology Policy (OSTP), said last week that it is “important for us to continue to emphasise the use of federal R&D dollars towards American scientists and technologists that are staffed by Americans in their labs.” Asked about support for Chinese students during a Congressional hearing, Kratsios went on to say that in future funding announcements, the OSTP would “emphasise” that “we're funding American students.”The precise meaning of his impromptu comments, and what they could mean in policy terms, isn’t yet clear. The OSTP did not respond to multiple requests for clarification from Science|Business.But given that US science and technology has relied on overseas talent for the past century, Kratsios’s words have alarmed former US science officials.Immigrants have made up around 30-40% of US Nobel Prize winners since the 1940s, for example. Except for some sensitive projects, countries typically grant research funding on a nationality-blind basis, lest they deter foreign scientists from immigrating. “If director Kratsios’s statements are taken literally and become official policy of the White House, [research-intensive] universities will likely have to close labs if not entire research divisions,” said David Biggs, a former science and technology official in the US State Department. In their most extreme interpretation, Kratsios’s comments would imply that foreign scientists established in the US would see access to funding curtailed. This would “result in many world-leading professors who work in the United States in fields that this administration considers a priority (like fusion energy, artificial intelligence, and quantum computing) leaving the country,” said Cole Donovan, a former US science diplomat, and now associate director at the Federation of American Scientists.CripplingHowever, given the context of the conversation, Kratsios may have been referring more narrowly to funding for doctoral or postdoctoral students. At the hearing, he said he wanted to see labs staffed by US citizens. But even this would have devastating consequences for the US science system, say former officials, because the country is so dependent on early-career foreign researchers. Recent statistics show that nearly half of those in the US with a PhD in science, technology, engineering or mathematics (STEM) are considered short-term visitors, or non-residents in the official terminology. If this included residents who are not yet citizens, the proportion would likely be even higher. “Foreign PhD students are really a significant and core part of the university STEM workforce, and postdocs is similarly large,” said Donovan. Preventing US-based academics from hiring them from overseas would be a serious blow, he said. “If it's the case that this administration intends to limit funding to labs staffed only with US citizens, the effect will be to cripple the American scientific enterprise,” said Chris Marcum, a former OSTP official. “To think that these researchers can simply be replaced is a pipe dream. The labs will close,” said Marcum. Go elsewhereAround half of US-trained postdocs are foreign-born, said Biggs. “If these top international students cannot get funding to do their research, or even if they hear that funding for foreign students has been greatly restricted and will be super competitive, they will no longer choose to study in the US and will go elsewhere.” It’s unclear for now if Kratsios’s comments will translate into a real policy shift. But they could add to turmoil in the US science system since Donald Trump took over as president one year ago.

Alarm over US plan to prioritise citizens in research funding
