OpenAI Researcher Forced to Leave U.S. After Green Card Denial
An OpenAI researcher instrumental in developing GPT-4.5 has departed the United States following the rejection of her green card application. Kai Chen, a Canadian national, announced her relocation to Vancouver after residing and working in the U.S. for 12 years. Colleagues decried the decision as counterproductive to maintaining U.S. dominance in artificial intelligence.
The incident highlights ongoing tensions between immigration policies and tech industry demands for specialized talent. Despite OpenAI CEO Sam Altman’s public advocacy for high-skill immigration, the company has not commented on this specific case. The researcher’s departure comes as nations worldwide compete fiercely for top AI expertise.
