Renowned AI Researcher Refused Green Card After 12 Years in the U.S.

A Canadian AI researcher, Kai Chen, who has been residing in the United States for 12 years and contributed to projects like ChatGPT, has faced challenges with her green card application. This was highlighted by her colleagues at OpenAI in a series of posts on X, formerly known as Twitter.
Background of the Immigration Situation
Immigration has been a contentious issue in the U.S., particularly during Donald Trump’s presidency, which focused on significant immigration restrictions and mass deportations. Many of these policies continue to face legal challenges, creating uncertainty for many individuals seeking permanent residency. Meanwhile, figures like Elon Musk and Vivek Ramaswamy have advocated for expanding programs like the H-1B visa, designed for high-skilled foreign workers, to encourage talent influx into the country.
Details of Kai Chen’s Case
Noam Brown, an AI researcher at OpenAI, expressed serious concern over the denial of Chen’s green card application. In a post, he stated, “It’s deeply concerning that one of the best AI researchers I’ve worked with, Kai Chen, was denied a U.S. green card today.” He emphasized that turning away skilled professionals could jeopardize the United States’ leadership in AI development.
Another OpenAI team member, Dylan Hunn, also spoke out in support of Chen, stating that her contributions were “crucial for GPT-4.5.” Hunn highlighted the failures of the immigration system, suggesting it was detrimental to both Chen and the broader tech landscape: “America needs her!”
As a result of the application denial, Chen is temporarily relocating to Vancouver, where she plans to continue her work remotely while the immigration issue is being addressed. She noted that she was hopeful about returning to the U.S. but was determined to make the best of her situation in Canada.
Updates on Chen’s Immigration Status
Brown later provided updates indicating that the denial of Chen’s green card may have stemmed from previous paperwork issues during her initial filing, which took place two years ago. Chen herself elaborated that she had been waiting three years for her application, which adds to the frustration of her current situation. She expressed a mix of disappointment and gratitude for support from her workplace during this challenging time.

Rights and Protections for Green Card Holders
The U.S. Citizenship and Immigration Services (USCIS) states that green card holders enjoy the right to permanent residency in the country, as long as they adhere to U.S. laws. This includes avoiding legal violations and fulfilling tax obligations. Additionally, green card holders can apply for jobs more freely than temporary visa holders, and traveling is generally easier, although they should not be away for more than six months at a time.
Importantly, a green card provides lawful permanent residence, distinguishing it from temporary visas. However, it is not equivalent to citizenship. Green card holders must renew their status every ten years and may apply for citizenship after three years of marriage to a U.S. citizen or five years otherwise.
Community Reactions
Employees from OpenAI and others in the technology sector have expressed their concerns regarding the immigration system’s impact on talent acquisition. Brown commented on the pervasive issues plaguing high-skilled immigration, noting the constant struggles faced by skilled workers. OpenAI CEO Sam Altman also remarked on the need for immigration reforms to maintain the U.S. as a favorable destination for talented individuals.
Experts in immigration law emphasize that addressing these issues is vital not just for individuals like Chen, but for the broader tech industry and the economy at large. As America’s competitive edge in technology and innovation hinges on attracting top talent, the immigration system’s effectiveness has become a critical focal point for policymakers.
Next Steps for Kai Chen
While the path ahead for Chen may take time, early indications suggest that resolving her green card situation is possible, potentially allowing her to return to the U.S. sooner rather than later.
