TL;DR
Tech professionals and researchers from abroad are declining US job offers and skipping conferences amid tougher border enforcement and visa rules since January. Organizers and companies report rising denials and deterrents, and some events and talent are shifting to other countries.
What happened
Since President Trump took office in January, foreign technologists and researchers have been steering clear of the United States for both short‑term travel and longer‑term work. Conference attendees report being denied entry at the border even with correct paperwork, and trade show managers say persuading overseas participants to attend US events has become increasingly difficult. Several show organizers are closing US‑based editions and exploring alternatives in Europe, Canada and Asia. Scientific meetings likewise report lower international turnout, with researchers citing visa delays and fears of detention or denial. Chinese tech professionals invited to CES faced unusually high visa denial rates, and some advisers in China say mentioning CES on applications can raise the risk of rejection. The administration’s new Restriction on Entry of Certain Nonimmigrant Workers includes a provision that employers must pay an annual $100,000 fee per H‑1B application, a change sources describe as a deterrent to hiring foreign tech talent. Major firms have also warned overseas staff to return promptly while advising limits on dependents’ travel.
Why it matters
- Reduced international attendance at US conferences may weaken knowledge exchange and collaboration in research and industry.
- Higher costs and stricter H‑1B rules could discourage companies—especially smaller ones—from hiring foreign technical staff.
- Shift of events and talent to rival hubs may erode the US position as a leading destination for global tech talent.
- Disruption and relocation of skilled workers could delay projects and exacerbate labor shortages for US employers.
