Recently, Kai Chen, a pivotal researcher at OpenAI, was compelled to terminate his 12-year tenure in the United States and return to Canada following the rejection of his green card application. Chen, a crucial contributor to the GPT-4.5 project, has sparked widespread alarm in the technology sector with the denial of his green card. Industry experts have cautioned that the United States' stringent immigration policies are resulting in the loss of top-tier talent, which could jeopardize its leading role in the field of artificial intelligence. OpenAI has officially stated that it is fully supporting Chen in addressing the green card issue, acknowledging that his departure will inevitably cause short-term disruptions.
