Since the 1970s, the U.S. government has initiated legal proceedings to expel just 137 of the estimated 10,000 suspected Nazi war criminals who immigrated to the U.S. after World War II.
At least 67 have been deported, extradited or left voluntarily, and 28 died while their cases were pending.
Jakiw Palij, a 95-year-old former labor camp guard, was the last living Nazi war criminal in the U.S. with an active deportation order. He was deported to Germany, Tuesday.
A look at other notable Nazi suspects removed from the U.S:
Hermine Braunsteiner Ryan
Ryan, a New York City housewife who hid her past as a ruthless death camp guard known as "The Stomping Mare," was the first suspected Nazi war criminal that the U.S. extradited for a war crimes prosecution.
The U.S. sent Ryan to West Germany in 1973, where she was convicted of multiple acts of murder while a guard at the Majdanek death camp in Nazi-occupied Poland.
She was also a guard at the Ravensbruck concentration camp in Germany.
Ryan's life sentence was shortened in 1996 because she was in failing health. She died three years later at age 79.
A court found Ryan was involved in the process of deciding whether inmates were sent to the gas chambers or were spared so they could perform forced labor.
John Demjanjuk
Demjanjuk, a Cleveland, Ohio autoworker born Ivan Mykolaiovych Demianiuk in Ukraine, was deported to Germany in 2009. He was convicted there in 2011 on charges he aided the deaths of more than 28,000 Jews as a guard at the Sobibor extermination camp in Nazi-occupied Poland.
Demjanjuk steadfastly denied involvement in the Holocaust, maintaining he was a victim of mistaken identity.
He died in a Bavarian nursing home in 2012 at age 91 while appealing. His conviction was unprecedented in German law because it was solely on the basis of serving as a camp guard, with no evidence he was involved in a specific killing.
Demjanjuk was extradited to Israel in 1986 and sentenced to death on charges he was "Ivan the Terrible," a guard who operated gas chambers at a camp where about 850,000 Jews were killed.
Israel's Supreme Court overturned that verdict, citing evidence "Ivan" was another man.
Feodor (Fyodor) Federenko
Fedorenko, the first suspected Nazi war criminal deported from the U.S. to the Soviet Union, was executed by firing squad in 1987 at age 79.
A Soviet court found the former Treblinka death camp guard guilty of treason, voluntarily joining the Nazis and participating in mass killings at the camp in Nazi-occupied Poland.
Fedorenko was deported in December 1984 after a seven-year battle to remain in the U.S., where he had worked in a Connecticut factory before retiring to Miami Beach.
The U.S. stripped his citizenship after finding he attained it by omitting references to his Nazi service.
Trial witnesses said they saw Fedorenko beating and shooting Jews.
Fedorenko did not deny he had worked at Treblinka, but said he did not participate in any killings, telling the court, "Jews were among my best friends."
Karl Linnas
Linnas, a concentration camp chief who settled on Long Island and worked as a land surveyor, was one of the highest-ranking Nazi collaborators expelled from the U.S.
Linnas was stripped of his citizenship in 1982 and sent to the Soviet Union in 1987, where he had been convicted in absentia three decades earlier on charges he had a hand in the deaths of 12,000 people at the Tartu concentration camp in Nazi-occupied Estonia.
Linnas died of heart failure at age 67 before he could face a firing squad.
Investigators said Linnas ordered guards to fire on prisoners as they kneeled along the edge of a ditch, causing them to fall directly into their graves.
Immigrating to the U.S. in 1951, Linnas claimed to be a person displaced by the war and failed to disclose his Nazi service. He gained citizenship in 1959.
Arthur Rudolph
Rudolph, one of Germany's most prominent rocket scientists, was brought to the U.S. after World War II because of his technical skills.
NASA awarded him a Distinguished Service Medal for achievements that included his central role in the Apollo project that put a man on the moon.
Decades later he was accused of "working thousands of slave laborers to death" in the Nazi factory that built the V-2 rocket.
Rudolph signed a settlement agreement with the U.S. in 1983.
He traveled on his U.S. passport to West Germany in 1984. Then he went to the U.S. General Consulate in Hamburg and renounced his citizenship. The West German government protested, but Rudolph remained there.
He was eventually granted German citizenship and collected U.S. Social Security benefits until his death in 1996 at age 89.
Valerian (Viorel) Trifa
Trifa, the former U.S. archbishop of the Romanian Orthodox church, relinquished his citizenship in 1980 and left for Portugal in 1984 after admitting he lied to immigration authorities to conceal pro-Nazi activities during World War II.
The U.S. government alleged Trifa had been an ardent Nazi supporter who wrote inflammatory newspaper articles and made anti-Jewish speeches as a member of the Iron Guard, a Romanian fascist group.
One speech, in January 1941, touched off four days of rioting in Bucharest that resulted in hundreds of deaths. Trifa denied any role in the riots.
Trifa attained a U.S. visa through the post-war displaced persons program.
He was interned in the Dachau and Buchenwald concentration camps but investigators said he never told refugee officials about special treatment he received.
Trifa died in 1987 at age 72.
