A U.S. immigration judge has ordered the deportation of former Nazi death camp guard Anton Geiser to Austria or any other country that will host him.

According to a statement released by the U.S. Justice Department, 85-year-old Geiser immigrated to the United Sates from Austria in 1956 and became a naturalized U.S. citizen six years later. In 2006, a federal court in Pennsylvania revoked Geiser’s citizenship after ruling he had served as a concentration camp guard during World War II.

“As a Nazi concentration camp guard during World War II, Anton Geiser must be held to account for his role in the persecution of countless men, women and children,” Assistant U.S. Attorney General Lanny Breuer said in a statement. “The long passage of time will not diminish our resolve to deny refuge to such individuals.”

During the court proceedings to revoke his U.S. citizenship, Geiser claimed that he was “coercively inducted into the Nazi Waffen SS, sent to the Russian front as a combat soldier and then assigned to serve as a guard at two concentration camps.”

He argued that he did not voluntarily serve as a guard, and was there for eligible to emigrate under the Refugee Relief Act of 1953.

“Without Anton Geiser and other members of the SS Death’s Head guard battalions, the Nazi concentration camp system could not have accomplished its diabolical objectives.” Said Eli Rosenbaum, Director of Human Rights Enforcement at the US Department of Justice.
