NASA has blocked
citizens with US visas from working on agency programs.
“NASA has taken internal action pertaining to Chinese nationals, including restricting physical and cybersecurity access to our facilities, materials, and network to ensure the security of our work.”
While NASA typically has restrictions for employing
nationals, citizens of China with US visas have historically been able to contribute to agency research as contractors, graduate students or university scientists.
But on Sep 5,
nationals who had been working with NASA were denied access to the agency’s data systems and from participating in meetings pertaining to their work, both in person and virtually.
