> But... Why on earth do the people filing an administrative subpoena not have to notify the interested parties too?
Generally they do - with some notable exceptions being if you're a non-citizen and you're no longer in the US, and it's either a criminal investigation or related to intelligence or national security.
Which is the case here:
> In September 2024, Amandla Thomas-Johnson was a Ph.D. candidate studying in the U.S. on a student visa when he briefly attended a pro-Palestinian protest.
> Weeks later, in Geneva, Switzerland
It is obviously not criminal, but I guess that you don't need much to qualify something as related to intelligence and national security, attending a pro-Palestinian protest may be enough.
