The U.S. space research agency has decided to block individuals from China, even those holding valid American visas, from accessing its facilities. This move effectively ends their ability to work either as students or contractors on projects within one of the world’s most prestigious scientific institutions. The information was first reported by Bloomberg, citing sources familiar with the matter.
The restrictions were introduced to safeguard systems, infrastructure, and communication networks from potential threats. On September 5, the affected individuals were notified they had lost access to all relevant tools and premises, thereby being immediately excluded from research and collaboration processes.
China has rapidly advanced its space program in recent years, raising concern among officials in Washington. Its astronauts have long been excluded from the International Space Station, as U.S. law prohibits the sharing of technical data with Beijing. Such policies further widen the gap between the two global powers.
Many young professionals from China who study or work in America are facing additional barriers, including difficulties in obtaining entry permits. In recent years, several alleged espionage cases have been reported, leading to increased scrutiny of scientists of Asian origin.
NASA’s public affairs officer, Bethany Stevens, confirmed that “internal actions” have been taken, including bans on physical presence and access to information systems. It is unclear whether the individuals affected were given prior notice, but reactions indicate the decision came suddenly and without warning.
