In 1979, Leibbrandt was barred from entering the United States by the U.S. Justice Department and State Department, for his participation in the murder of hundreds of thousands of Jews, in his position as Chief of the Political Division of the Reich Ministry for the Occupied Eastern Territories from 1941 to 1943.  His United States visa was revoked and his name was placed on the watch lists of the U.S. Immigration Service and State Department, so he could not enter the United States.
