Vivian Chike Obichere

Convicted and denaturalized. Obichere was convicted in 2015 of making a false statement in a passport application and use of a passport, a conviction she admitted as part of her criminal case, and on October 13, 2026, a federal court revoked her U.S. citizenship by consent judgment in a civil denaturalization action.

Introduction

Vivian Chike Obichere, a native of Nigeria, is a former naturalized U.S. citizen whose citizenship was revoked by the U.S. District Court for the Northern District of California on October 13, 2026, after the Department of Justice proved she illegally procured naturalization by concealing a decades-long identity fraud . The Justice Department announced the denaturalization on October 21, 2026, presenting it as part of what Assistant Attorney General Brett A. Shumate of the Civil Division called a “historic denaturalization campaign” . Her case is one of two denaturalizations announced that day, alongside the revocation against Milagros Marileisis Acosta Torres .

Background Information

According to the Justice Department, Obichere has “a long history of defrauding the U.S. government” . In 1992, she fraudulently used the name, social security number, birthplace, and birthdate of a U.S. citizen identified in court papers only as “C.C.O.” to illegally obtain a U.S. passport, and she successfully renewed that fraudulent passport in 2002 . In 2003, she became a lawful permanent resident under her true identity — yet in 2012 she attempted to renew the fraudulent alias passport a second time while simultaneously applying to naturalize under her real name .

The Controversy or Incident That Led to Their Cancellation

The pivotal act, per the government, came during her naturalization process. At her naturalization interview, Obichere “orally testified under oath that she had not used the name C.C.O.,” testimony the department says she gave knowing it was false and while lying to secure an immigration benefit . She became a naturalized U.S. citizen in 2013, at what the release describes as the same time her fraud scheme was unraveling . In 2015, she was convicted in the Northern District of California of False Statement in Application and Use of Passport, and as part of that criminal conviction she admitted the lies described above as well as “many others she had told the U.S. government over the years” .

Public Reaction and Consequences

The denaturalization machinery moved quickly once the Civil Division filed suit. On July 30, 2026, the department filed a denaturalization complaint against Obichere; on October 7, the parties filed a joint motion for entry of a consent judgment revoking her naturalization; and on October 13, the court issued the judgment revoking her citizenship . Shumate framed the outcome in blunt terms: “Securing denaturalization is the final step to strip citizenship from those who conceal crimes or defraud the American people,” adding that the administration “will continue its historic denaturalization campaign to protect the value of U.S. citizenship” . The release announcing her case carried the department’s own theme that denaturalization is reserved for people who obtained citizenship illegally in the first place, not a secondary punishment for unrelated conduct .

Current Status

Obichere’s naturalization was vacated by the October 13, 2026 judgment, which means she is no longer a U.S. citizen; her lawful-permanent-resident status from 2003 is what the record shows beneath the revoked citizenship . The consent-judgment posture means she joined the motion revoking her own naturalization rather than litigating it to a verdict . The Justice Department’s release does not describe any new criminal case arising from the denaturalization, and no removal proceedings are mentioned in the announcement .

Impact on Their Career/Life

Twenty-plus years of accumulated status — the alias passport, the renewal, the green card, the 2013 naturalization — were undone in a single civil judgment, and the underlying passport-fraud conviction remains a matter of court record. Obichere’s case has become one of the publicized examples of the DOJ’s revived denaturalization docket, cited alongside Acosta Torres to signal that concealment of past crimes during naturalization carries the ultimate immigration consequence: the loss of citizenship itself.
