Padilla Clarity Rule: For Truly Clear Deportation Consequences, Counsel Must Warn of Practically Inevitable Removal (Tenth Circuit)

1. Introduction

United States v. Aguayo-Montes (10th Cir. Mar. 17, 2026) is a published decision addressing when the Sixth Amendment requires defense counsel to provide specific, non-equivocal immigration advice during plea negotiations. Cesar Aguayo-Montes, a long-time U.S. resident who received DACA relief, pleaded guilty to a federal heroin offense under 21 U.S.C. § 841(a)(1). Before pleading, he asked counsel about immigration consequences. Counsel allegedly stated he was not an immigration attorney, could not say what would happen, and that Aguayo need not worry until prison, where he could consult an immigration lawyer.

After learning the plea made deportation “practically inevitable,” Aguayo filed a 28 U.S.C. § 2255 motion alleging ineffective assistance of counsel under Padilla v. Kentucky, 559 U.S. 356 (2010). The district court denied relief on the theory that Aguayo was adequately warned because the plea agreement (and Rule 11 colloquy) stated he “may” be removed. The Tenth Circuit reversed on deficient performance and remanded for a prejudice determination.

Key issue: When removal is “truly clear” under immigration law for the charged offense, does counsel satisfy Padilla by warning only that deportation is a “risk” or “may” occur, or must counsel convey that removal is automatic/presumptively mandatory/practically inevitable?

2. Summary of the Opinion

The Tenth Circuit held that, under Padilla v. Kentucky, counsel’s duty scales with clarity: when immigration consequences are “truly clear,” counsel must provide “equally clear” and “correct” advice. A § 841(a)(1) heroin conviction is a deportable controlled-substance offense under 8 U.S.C. § 1227(a)(2)(B)(i), making deportation “automatic,” “presumptively mandatory,” or “practically inevitable” in Padilla’s sense. Therefore, advising only that the defendant “may” be removed is constitutionally insufficient.

The court also found that the alleged advice—“don’t worry until prison; consult an immigration lawyer later”—amounted to affirmative misadvice because it implies immigration consequences are either not serious or not knowable at the plea stage, depriving the defendant of the chance to negotiate or litigate with immigration stakes in mind.

The panel reversed the district court’s deficient-performance ruling and remanded for fact development on prejudice (whether Aguayo would have rejected the plea but for counsel’s errors), guided by Lee v. United States, 582 U.S. 357 (2017).

3. Analysis

3.1. Precedents Cited

• Padilla v. Kentucky, 559 U.S. 356 (2010)
  Role in the decision: The controlling rule. The panel emphasized Padilla’s dichotomy: (a) if deportation consequences are “unclear or uncertain,” counsel need only advise that charges “may” carry a risk; (b) if consequences are “truly clear,” counsel must give “equally clear” and “correct” advice. The court treated controlled-substance deportability as Padilla’s paradigmatic “truly clear” category and required counsel to convey the practical inevitability of deportation, not merely its possibility.
• Chaidez v. United States, 568 U.S. 342 (2013)
  Role: The government relied on Chaidez’s phrasing about “advice about the risk of deportation.” The panel responded that advising “about” risk entails qualitative assessment, especially where law is clear, and cannot erase Padilla’s “clear vs. unclear” structure.
• Strickland v. Washington, 466 U.S. 668 (1984) and Hill v. Lockhart, 474 U.S. 52 (1985)
  Role: Provide the two-prong ineffective-assistance framework (deficient performance + prejudice), with Hill supplying the plea context.
• Lee v. United States, 582 U.S. 357 (2017)
  Role: Governs the prejudice inquiry in immigration-advice plea cases: whether there is a reasonable probability the defendant would have rejected the plea had he received competent advice, assessed under the “totality of the evidence,” including ties to the U.S. and the defendant’s priorities.
• Missouri v. Frye, 566 U.S. 134 (2012), Lafler v. Cooper, 566 U.S. 156 (2012), and Montejo v. Louisiana, 556 U.S. 778 (2009)
  Role: Reinforce that plea bargaining is a “critical stage” at which the Sixth Amendment applies; the court used Frye to underscore that effective legal aid must occur at the plea stage—where advice can still change outcomes.
• Massiah v. United States, 377 U.S. 201 (1964)
  Role: Quoted through Frye to support the proposition that effective assistance matters “at the only stage” where advice can help—here, plea negotiations rather than post-sentencing immigration consultation.
• Delgadillo v. Carmichael, 332 U.S. 388 (1947) and INS v. St. Cyr, 533 U.S. 289 (2001)
  Role: Frame deportation as “banishment or exile” and recognize that immigration consequences may matter more than the jail sentence—supporting why Padilla requires meaningful advice, not boilerplate warnings.
• Sessions v. Dimaya, 584 U.S. 148 (2018)
  Role: Cited for the practical severity of aggravated-felony classification (“virtual[ly] certain[] removal”), though the panel declined to decide whether counsel must use “virtual certainty” language because Padilla’s controlled-substance clarity sufficed.
• United States v. Barrett, 797 F.3d 1207 (10th Cir. 2015) and United States v. Rushin, 642 F.3d 1299 (10th Cir. 2011)
  Role: Establish de novo review where the district court denies a § 2255 motion without an evidentiary hearing.
• Childers v. Crow, 1 F.4th 792 (10th Cir. 2021) and Cutter v. Wilkinson, 544 U.S. 709 (2005)
  Role: Support the court’s refusal to decide prejudice “in the first instance” on appeal.
• Williams v. Taylor, 529 U.S. 362 (2000)
  Role: Provides the “totality of the evidence” lens for evaluating prejudice, as incorporated by Lee.
• United States v. Ramirez-Jimenez, 907 F.3d 1091 (8th Cir. 2018)
  Role: The principal published circuit authority the government invoked; the Tenth Circuit distinguished it factually because counsel there said deportation was “likely,” whereas Aguayo alleged he received only a “may” warning and delay-to-prison framing.
• United States v. Rodriguez-Vega, 797 F.3d 781 (9th Cir. 2015) and United States v. Swaby, 855 F.3d 233 (4th Cir. 2017)
  Role: Persuasive support for the principle that “mere potential” or generic “risk” advice is deficient when removal is clear, and that plea agreements/Rule 11 warnings are irrelevant to whether counsel’s performance was objectively reasonable.
• Doe v. United States, 915 F.3d 905 (2d Cir. 2019)
  Role: Persuasive authority condemning advice that fails to convey mandatory deportation consequences.
• Other persuasive authorities discussed as consistent with the panel’s approach include: United States v. Fazio, 795 F.3d 421 (3d Cir. 2015), United States v. Armendariz, 80 F.4th 546 (5th Cir. 2023), Hernandez v. United States, 778 F.3d 1230 (11th Cir. 2015), Diaz v. State, Martin v. United States, Barrie v. United States, Araiza v. State, Budziszewski v. Comm'r of Corr., Encarnacion v. State, Commonwealth v. DeJesus, Hernandez v. State, State v. Sandoval, and contrasting views in State v. Sanmartin Prado and State v. Shata.

3.2. Legal Reasoning

1. Padilla’s clarity framework is operative, not decorative.
   The court treated Padilla’s “unclear/uncertain” vs. “truly clear” distinction as outcome-determinative. If “may be removed” sufficed even when deportation is practically inevitable, then the “clear” category would collapse into the “uncertain” category—contradicting Padilla’s express text requiring “equally clear” advice when consequences are “truly clear.”
2. A § 841(a)(1) heroin plea has “truly clear” deportation consequences.
   The panel grounded clarity in the statutes themselves. A federal conviction “relating to a controlled substance” (heroin) is deportable under 8 U.S.C. § 1227(a)(2)(B)(i), with heroin identified as a schedule I controlled substance under 21 U.S.C. § 802 and 21 U.S.C. § 812. This is the same kind of “read the removal statute” clarity Padilla singled out for drug distribution offenses.
3. Therefore, the constitutionally adequate message is not “may,” but “automatic/presumptively mandatory/practically inevitable.”
   The court did not require counsel to guarantee deportation will occur in every real-world sense, but did require counsel to convey the legal effect: the conviction makes the defendant deportable in a way that renders removal the expected and near-inevitable consequence. “May” was deemed materially under-informative for a decision as consequential as whether to plead.
4. Plea agreement language and Rule 11 warnings do not cure counsel’s deficient performance.
   The panel echoed United States v. Rodriguez-Vega: the court’s generic advisement under Fed. R. Crim. P. 11(b)(1)(O) and boilerplate plea warnings are not substitutes for counsel’s individualized advice. The Sixth Amendment inquiry is about counsel’s objective reasonableness, not whether the defendant encountered generic cautionary text.
5. “Don’t worry until prison” is affirmative misadvice in this context.
   Because immigration consequences are crucial precisely during negotiations (when one can seek an immigration-safer charge, sentence, or trial strategy), deferring immigration concern to a post-plea future misleads the defendant about when the decision must be made. The panel analogized this to the misleading reassurance described in Padilla.
6. Prejudice requires fact development under Lee, and the panel would not decide it first on appeal.
   The district court had not conducted the “intensely factual” prejudice inquiry, and the existing record mainly consisted of allegations in the motion. Applying Lee v. United States, the panel remanded for examination of the totality of evidence (ties, priorities, plausibility of alternative outcomes, etc.).

3.3. Impact

• Clear-duty articulation for controlled-substance pleas in the Tenth Circuit.
  This published decision squarely holds that, for deportable controlled-substance offenses where the law is “truly clear,” counsel must communicate the practical inevitability of removal—warnings framed as mere possibility (“may”) are inadequate.
• Expanded exposure to § 2255 litigation where counsel relied on boilerplate warnings.
  Defendants who received only plea-form/Rule-11 “may be removed” language (or equivalent generic statements) now have stronger arguments that counsel’s performance was deficient if the offense is plainly deportable.
• Practice change: earlier, more specific immigration counseling (or referral) is constitutionally necessary.
  The opinion stresses that immigration consequences must be assessed during plea negotiations, when “creative” bargaining may reduce removal risk—counsel cannot push the issue to “after sentencing.”
• Limits on “semantic” defenses.
  The court rejected the government’s attempt to treat “risk” language as universally sufficient; what matters is whether the advice meaningfully distinguishes “truly clear” deportation consequences from uncertain ones.
• Prejudice remains the battleground.
  Because the court remanded, future litigation will likely focus on Lee’s prejudice factors—e.g., whether a defendant with deep U.S. ties would rationally reject a favorable plea to preserve even a slim chance to avoid deportation, and whether any alternative plea was realistically available.

4. Complex Concepts Simplified

28 U.S.C. § 2255 motion

A post-conviction procedure allowing a federal prisoner to ask the sentencing court to vacate or correct a conviction/sentence based on constitutional or other serious legal errors.

Ineffective assistance of counsel (Strickland/Hill)

A Sixth Amendment claim requiring (1) deficient performance (objectively unreasonable lawyering) and (2) prejudice. In plea cases, prejudice usually means a reasonable probability the defendant would have rejected the plea and gone to trial (or sought a different plea) with proper advice.

Padilla duty

Defense counsel must advise about deportation consequences of a plea. If immigration consequences are unclear, a general warning of possible risk may suffice. If consequences are truly clear, counsel must say so clearly and correctly.

“Controlled-substance offense” (deportability)

Immigration law makes noncitizens deportable for convictions involving controlled substances. Here, heroin is a federally defined controlled substance, so a heroin trafficking conviction clearly triggers deportability.

Rule 11(c)(1)(C) plea

A plea agreement in which the parties agree to a specific sentence (or range) that binds the court if accepted.

Rule 11(b)(1)(O) immigration warning

A required, standardized warning by the judge that a guilty plea may affect immigration status; the court held this generic warning does not substitute for counsel’s tailored advice.

DACA

A discretionary program granting renewable temporary protection from removal for certain individuals who arrived as children without authorization; it does not eliminate the immigration consequences of serious criminal convictions.

5. Conclusion

United States v. Aguayo-Montes strengthens and concretizes Padilla’s “clarity” framework in the Tenth Circuit: when immigration law makes deportation consequences “truly clear,” defense counsel must provide equally clear advice—warning that removal is “automatic,” “presumptively mandatory,” or “practically inevitable,” not merely that the defendant “may” be removed. The court also treats “don’t worry until prison” guidance as misleading because it shifts attention away from the only stage when immigration-aware strategy can matter—plea negotiations.

By reversing on deficient performance and remanding on prejudice under Lee v. United States, the opinion both raises the performance bar for immigration advice in clear-consequence cases and signals that the decisive question in many future cases will be whether, in the totality of circumstances, the defendant would have made a different plea decision if properly informed.
