Oscar Alberto Pelaez, a former Colombian priest, is facing revocation of his U.S. citizenship after the Department of Justice filed a civil lawsuit alleging he deliberately concealed his crimes during naturalization. Pelaez was granted citizenship in 2001, but pleaded guilty in 2002 to 13 felonies for sexually abusing a 14-year-old parishioner between 1998 and 2000. He had falsely attested on his citizenship application that he had no criminal record. The case was revived following a recent investigation as part of a broader effort to identify cases where immigration benefits were obtained through false information.

Debashis Ghosh, a 62-year-old Indian-American businessman, faces denaturalization after the Department of Justice moved to revoke his U.S. citizenship. Ghosh became a U.S. citizen in 2012 but falsely claimed during his naturalization application that he had no criminal history. He was convicted of wire fraud in 2017 involving a $2.5 million investor fraud scheme from 2010-2014, which he concealed during citizenship proceedings. Authorities allege he conspired to defraud investors of funds intended for an aircraft maintenance facility and misrepresented the safekeeping of investor money. Ghosh is among 12 individuals targeted by the Justice Department for denaturalization on various charges including fraud, war crimes, and support for terrorist groups.

The DOJ filed denaturalization actions against Ali Yousif Ahmed Al-Nouri, a Phoenix-area resident, alleging he obtained U.S. citizenship through fraud by claiming al-Qaida attacked him and his family when entering in 2009.

The DOJ determined in 2015 that he had lied during the naturalization process.

Victor Manuel Rocha, a former U.S. ambassador to Bolivia and State Department official, was convicted in 2024 of conspiring to act as an agent for Cuban intelligence services for over 50 years beginning in 1973. Rocha obtained U.S. citizenship in 1977-1978 through false statements, concealing his communist affiliations and espionage activities. He is serving a 15-year prison sentence. In May 2026, federal prosecutors filed a civil denaturalization complaint seeking to revoke his citizenship, alleging he fraudulently obtained naturalization by lying about his ties to Cuba and the Communist Party and concealing his decades-long work as a covert intelligence operative.

Abdallah Osman Sheikh, a resident of Fairdale, Kentucky, was targeted for denaturalization for concealing that he possessed indecent digital images of two minors in July 2019 while serving in the Marines and posted such an image to social media.

The U.S. Department of Justice filed a denaturalization lawsuit against Abduvosit Razikov, a 46-year-old Uzbek citizen, alleging he obtained permanent residency and U.S. citizenship through fraudulent means. According to the complaint, Razikov paid for a fake marriage in 2005 to obtain a green card, organized additional fraudulent marriage schemes for others, and gave false statements during naturalization proceedings in 2012. The DOJ argues his citizenship should be revoked because it was obtained through fraud and concealment of material facts.

Kevin Robin Suarez, a native of Bolivia, was targeted for denaturalization after pleading guilty in 2020 to conspiracy involving the illegal purchase and trafficking of firearms through straw purchasers from South Florida to Bolivia and other Latin American countries for drug trafficking organizations.

The U.S. Department of Justice has filed a case to revoke the citizenship of Baboucarr Mboob, 58, a native of Ndungu Kebbeh, Gambia, accusing him of concealing war crimes during his U.S. naturalization in 2011. Mboob, who entered the U.S. in 2002, previously served as a military police officer and orderly under former Gambian president Yahya Jammeh, and in 2019 testimony before The Gambian Truth, Reconciliation and Reparations Commission admitted to participating in the 1994 execution of six fellow officers, naming five victims: Lt. Gibril Saye, Lt. Buba Jammeh, Lt. Bakary Manneh, Cadet Amadou Sillah and Lt. Abdoulie Bah. The case is part of a broader DOJ action against 12 individuals accused of offenses including war crimes, support for terrorism and sexual abuse of a minor, with acting Attorney General Todd Blanche stating that those who concealed such histories during naturalization will face legal consequences.

The U.S. Department of Justice filed a civil complaint in federal court seeking to denaturalize Salah Osman Ahmed, a naturalized U.S. citizen from Minnesota. Ahmed was naturalized in August 2007, months before providing material support to al-Shabaab, a designated foreign terrorist organization. In 2009, he pleaded guilty to one count of providing material support to terrorists after admitting to attending secret meetings in Minneapolis in 2007, traveling to Somalia in December 2007 to help build a training camp, receiving weapons training including on PKM machine guns, and raising money from the Somali-American community. He served three years in prison and was granted relief from supervised release in 2022. The DOJ contends Ahmed was not genuinely attached to U.S. constitutional principles at the time of naturalization and must prove by clear and convincing evidence that his citizenship was not obtained through fraud or misrepresentation.

Khalid Ouazzani, a native of Morocco, was targeted for denaturalization after pleading guilty in 2010 to bank fraud, money laundering, and providing material support to Al-Qaeda.

The complaint also alleges he obtained permanent resident status through an invalid marriage to a U.S. citizen using a fraudulent divorce certificate.
