A Canadian AI researcher, Kai Chen, who has lived in the U. S. for 12 years and contributed to ChatGPT at OpenAI, was denied a green card, according to OpenAI employees on X (formerly Twitter). Newsweek contacted the U. S. Citizenship and Immigration Services (USCIS) for comment outside normal hours. This case highlights ongoing challenges in U. S. immigration policy. Under President Trump, immigration underwent strict crackdowns including proposed mass deportations, despite legal obstacles. Meanwhile, figures like Elon Musk and Vivek Ramaswamy – both initially appointed by Trump to lead the Department of Government Efficiency (DOGE) – advocated expanding high-skill visa programs such as the H-1B visa, which allows U. S. employers to hire foreign workers temporarily for nonagricultural jobs. On Friday, OpenAI researcher Noam Brown expressed serious concern on X about Chen’s immigration status, emphasizing that rejecting such talent jeopardizes America’s AI leadership. Another OpenAI employee, Dylan Hunn, called Chen “incredibly important” and crucial to GPT-4. 5 development, criticizing the immigration system for forcing her departure. Chen plans to continue working remotely from Vancouver while resolving her situation, maintaining optimism despite the indefinite timeline. Brown later suggested paperwork issues from Chen’s initial green card filing two years ago might be the cause.

Chen clarified she applied three years ago prior to joining OpenAI and, though disappointed by the denial after a long wait, feels fortunate overall. OpenAI confirmed they were not involved with the initial application but are actively supporting Chen. Green card holders enjoy permanent residency rights in the U. S. , including protection under all local laws, easier employment opportunities, and less restrictive travel compared to temporary visas. They must avoid actions that could make them removable, renew their cards every ten years, and may apply for citizenship after three to five years depending on marital status. Immigration lawyer Eliss Taub highlighted that green cards provide lawful permanent residence, distinct from citizenship. OpenAI and employees voiced frustration over the systemic issues in U. S. high-skilled immigration. Brown noted persistent “visa horror stories” limiting progress week to week, while CEO Sam Altman called high-skill immigration reform an easy policy win essential to retaining global talent. Independent contractor Shaun Ralston criticized the Trump administration’s impact on the talent pipeline despite OpenAI filing numerous H-1B visas last year. Meanwhile, businesses are striving to ensure compliance with employment documentation as immigration complexities increase. Chen’s green card application remains pending, but identification of paperwork problems offers hope for timely resolution and a potential return to the U. S. OpenAI continues to work closely with her on the case. (Update April 26, 2025: article includes OpenAI statement. )
