 Zündel returned to his childhood home in the Black Forest, which had been vacant since his mother's death in the 1990s, and lived there until his own death.On March 31, 2017, the U.S. Department of Homeland Security Administrative Appeals Office ruled Zündel inadmissible to the United States, rejecting his application for an immigrant visa which he had sought in order to be reunited with his wife.He was classified as inadmissible, because he has been convicted of foreign crimes for which the sentence was five years or more and a waiver deemed unwarranted due to Zündel's "history of inciting racial, ethnic, and religious hatred".
