In an opinion piece for Computerworld, columnist Steven Vaughan-Nichols argues that restrictive visa policies and a hostile border climate under the Trump administration are driving foreign tech workers, researchers, and conference speakers away from the U.S. The result, he says, is a gradual shift of talent, events, and long-term innovation toward more welcoming regions such as Europe, Canada, and Asia. From the report: I go to a lot of tech conferences -- 13 in 2025 -- and many of those I attend are outside the U.S.; several are in London, one is in Amsterdam, another in Paris, and two in Tokyo. Wherever I went this past year, when we weren't talking about AI, Linux, the cloud, or open-source software, the top non-tech topic for non-Americans involved the sweeping changes that have occurred since President Donald J. Trump returned to office last January. The conversations generally ended with something like this: "I'm not taking a job or going to a conference in the United States." Honestly, who can blame them? Under Trump, America now has large "Keep Out!" and "No Trespassing!" signs effectively posted. I've known several top tech people who tried to come to the U.S. for technology shows with proper visas and paperwork, but were still turned away at the border. Who wants to fly for 8+ hours for a conference, only to be refused entry at the last minute, and be forced to fly back? I know many of the leading trade show organizers, and it's not just me who's seeing this. They universally agree that getting people from outside the States to agree to come to the U.S. is increasingly difficult. Many refuse even to try to come. As a result, show managers have begun to close U.S.-based events and are seeking to replace them with shows in Europe, Canada, and Asia. [...] Once upon a time, everyone who was anyone in tech was willing to uproot their lives to come to the U.S. Here, they could make a good living. They could collaborate, publish, and build companies in jurisdictions that welcome them, and meet their peers at conferences. Now, they must run a gauntlet at the U.S. border and neither a green card nor U.S. citizenship guarantees they won't be abused by the federal government. Trump's America seems bound and determined to become a second-rate tech power. His administration can loosen all the restrictions it wants on AI, but without top global talent, U.S. tech prowess will decline. That's not good for America, the tech industry or the larger world.
