Ukrainian arms smuggler Vladimir Volgaev, Cuban woman Cabrera Diaz and Lebanese man Alec Nasreddine Kasir. All three held U.S. citizenship until the Donald Trump administration uncovered their criminal evidence and stripped them of their U.S. citizenship, making it clear that obtaining U.S. citizenship does not shield individuals from punitive action and that citizenship can be revoked. “U.S. citizenship is a sacred privilege, not a cheap status obtained dishonestly,” said Attorney General Pamela Bondi. “These actions reflect the Department of Justice’s ongoing efforts to strip citizenship from those who conceal their crimes or deceive the American people during the immigration process.”
Ukrainian arms smuggler Vladimir Volgaev
Beginning in 2011, Volgaev was involved in purchasing, packaging, and smuggling gun parts to individuals in Ukraine and Italy. On September 30, 2025, the Department of Justice filed a lawsuit in the U.S. District Court for the Middle District of Florida, seeking to revoke Volgaev’s citizenship based on his crimes and those he failed to disclose during the naturalization process.On March 23, the court ordered the revocation of Volgaev’s U.S. citizenship. The court held that Volgaev had violated the law in the period before naturalization and required him to show good moral character, so he was not eligible for naturalization. Additionally, the court found that Volgaev gave false testimony about his criminal background and obtained U.S. citizenship by knowingly misrepresenting those facts.
Cuban woman Cabrera Diaz
Mirelys Cabrera Diaz is a Cuban native and a resident of Hialeah, Florida. She became a naturalized U.S. citizen in 2017. She committed health care fraud between 2011 and 2014 before naturalizing. She admitted that she and her co-conspirators paid kickbacks to patient recruiters for referring fraudulent prescriptions to the pharmacy where she worked.A U.S. District Court ruled that Cabrera Diaz was an illegal naturalized citizen. Among the naturalization requirements, Cabrera Diaz was required to prove that she is a person of good moral character within the “legal period” of five years before applying for naturalization and the oath of naturalization. The court concluded that she was unable to establish the good moral character required for naturalization because she conspired to commit health care fraud.
Lebanese criminal Alec Nasreddin Kasir
Cassirer committed marriage fraud because he claimed he had been living with his U.S. citizen spouse for three years before filing his naturalization application in March 2010. On November 14, 2018, he pleaded guilty to passport fraud in the Southern District of Florida. Cassirer admitted in the criminal complaint that he obtained a U.S. passport through fraudulent naturalization. He admitted that he did not live with his alleged U.S. citizen spouse or even in the same state; instead, they separated in 2009 and Cassirer moved to Florida. Cassirer was convicted of conspiracy to commit money laundering after his naturalization and immigration fraud was uncovered during an investigation into his trafficking in counterfeit goods.
