WASHINGTON — A German graduate student in oceanography at M.I.T. applied to the Transportation Security Administration for a new ID card allowing him to work around ships and docks.
What the student, Wilken-Jon von Appen, received in return was a letter that not only turned him down but added an ominous warning from John M. Busch, a security administration official: “I have determined that you pose a security threat.”
Institute officials were also disturbed. The agency controls airport security, and “our students travel in and out of the country a lot,” said Danielle Guichard-Ashbrook, associate dean and director of the international student office at M.I.T.
