Loss of Citizenship & Denaturalization

How U.S. law protects citizenship once acquired — the doctrine of voluntary relinquishment and the limits on denaturalization.

Court activity

  • Afroyim v. Rusk (1967)

    The government may not revoke citizenship without the individual's voluntary relinquishment.

  • Vance v. Terrazas (1980)

    Expatriation requires a specific intent to relinquish citizenship, not merely a potentially expatriating act.

  • Maslenjak v. United States (2017)

    Denaturalization on the basis of a false statement requires that the lie was material to the decision to naturalize.
