Is US losing human resource in Science?

In response to your news feature (Nature 648, 530-531 (2025), I share a first hand experience of how the US is losing its immigrant pool of scientists and professors who actually are integral part of the shining US science and Technology (1). I was almost offered a lectureship job in Biochemistry and Molecular Biology in University of Texas but due to Trump administration new regulations my appointment was cancelled and now with heavy fees imposed on H1B visas ( almost 1 million USD for Indians), I don't see any any remote possibility of joining the US higher education academia. I had given several interviews in US Universities in the past couple of years but now I have stopped applying because the scenario is bleak. Long ago, in 2017, celebrated Physicist Michio Kaku commented that the H1B visa attracts more talent to the USA than anything else (2). Being able to attract global talents to live the American dream has fueled American innovations in the past. Professor Kaku predicted rightly without immigration, "we’d be a third-rate country," (2). Already China has flipped the card by leading Tech Innovations (3) and this year and the number of Indian H1B visa applicants were slashed down by 70% as compared to 2015, hitting an all time low (4). I know several Indian post docs in my circle faced job cuts and this will open a floodgate of exits of talented scientists and professors from the US to reach the greener pastures of China, South East Asia and the Middle East. In fact, China has now introduced a new visa , K visa to attract global talents post Trump visa blockage (5). Overall, the Trump administration is blocking the immigration via Science and Tech which will impact more than fund cuts because of talent shortage. References; 1.
