Background
Karnail Singh, a naturalized U.S. citizen, pled guilty to using a fraudulently obtained passport after making false statements on immigration applications. He later sought to set aside his conviction via a writ of coram nobis, claiming ineffective assistance of counsel because his attorney failed to warn him that the plea could lead to denaturalization. The district court denied the petition, and the Sixth Circuit previously affirmed that decision before the Second Circuit issued a conflicting en banc ruling in Farhane v. United States.
The court’s reasoning
The court distinguished denaturalization from deportation, noting that while Padilla v. Kentucky created a narrow exception for deportation due to its severity and automatic nature, denaturalization remains a collateral consequence. The Sixth Amendment guarantees assistance of counsel for the defense in criminal prosecutions but does not extend to advising on follow-on civil proceedings like denaturalization suits, which are beyond the control of the criminal court.
Simply put, neither the Sixth Amendment nor Supreme Court precedent applying it requires attorneys to advise naturalized citizens that a guilty plea may carry the risk of denaturalization and eventual deportation.
United States v. Singh, No. 25-1523 (6th Cir. May 5, 2026)
What it means going forward
Criminal defense attorneys in the Sixth Circuit are not constitutionally mandated to inform naturalized clients of the specific risk of denaturalization when entering a guilty plea, though they remain responsible for advising on direct consequences like imprisonment.
