Reversed and remanded by published opinion. Judge DONALD RUSSELL wrote the opinion, in which Chief Judge ERVIN and Judge HAMILTON joined.
OPINION
On July 19, 1993, a federal jury convicted Warren Harding McNamara, Jr. (“McNamara”) of illegally structuring financial transactions to avoid currency reporting requirements in violation of 31 U.S.C. § 5324(a)(3) (“antistructuring law”) and § 5322(a). He received twenty-one months imprisonment, three years supervised release, and a $4,000 fine. One year later after forgoing direct appeal of either his conviction or sentence, McNamara filed a motion under 28 U.S.C. § 2255 asking the district court to vacate his sentence. He advanced two grounds for his motion: (1) that he was denied effective assistance of counsel because his trial counsel had failed to object to the jury instruction on the “willfulness” element of unlawful structuring; and (2) that there had been an intervening substantive change in the antistruc-turing law which required a reversal of his conviction.
The district court found ineffective assistance of counsel and granted McNamara’s motion, vacating his sentence and ordered a new trial.
McNamara v. United States, 867
F.Supp. 369 (E.D.Va.1994). The district court reasoned that McNamara’s trial counsel should have objected to the jury instruction because at the time of trial, the Supreme Court had granted
certiorari
in
United States v. Ratzlaf,
I.
The antistructuring law under which McNamara was convicted makes it a crime for an individual to “structure or assist in structuring or attempt to structure or assist in structuring, any transaction with one or more domestic financial institutions.” 31 U.S.C. § 5324(a)(3). And section 5322(a) provides the punishment for a person
“willfully violating
this subchapter or a regulation prescribed under this sub chapter....” 31 U.S.C. § 5322(a) (1988),
amended by
31 U.S.C.A. § 5322(a) (Supp.1994) (emphasis added). This Circuit’s controlling authority, in 1993, did not require the defendant to have specific knowledge of the illegality of his conduct.
See United States v. Rogers,
Following the Supreme Court’s Ratzlaf decision, the district court found that if McNamara’s trial counsel had more thoroughly prepared for trial, his research would have discovered the certiorari grant in Ratzlaf and he would have preserved the issue for appeal. Specifically, the district court concluded that:
[A] lawyer must be aware of the fact that an element of an offense he must defend at trial is under examination by the Supreme Court, particularly where the decision on that issue has the potential to alter the controlling rule in the circuit and likely will be issued while his client’s case is on direct appeal if an appeal is taken. At least at the confluence of these factors, it is beyond the wide range of acceptable professional conduct to be unaware of developments in the law.
McNamara,
In accordance with our recent opinion in
Komahrens,
we find the district court’s reasoning unpersuasive. In
Kornahrens,
we examined whether Kornahrens’ trial counsel was constitutionally ineffective for failing to preserve an issue at trial based merely on the Supreme Court’s grant of
certiorari
in a case which raised the issue. Specifically, at the time of Kornahrens’ trial, South Carolina law prohibited the proffering of expert evidence of future adaptability. The Supreme Court had granted
certiorari
in
State v. Skipper,
We find Komahrens directs this case’s disposition. Like Komahrens, McNamara’s trial counsel, mindful of the controlling circuit law at the time, had no basis for objecting to the willfulness element of the given jury instruction. Furthermore, post-trial testimony reveals that McNamara’s trial counsel made adequate efforts to prepare himself for trial. In light of these facts and our previous decisions, we conclude that the district court erred in finding McNamara’s trial counsel to be constitutionally deficient.
II.
Although McNamara’s § 2255 motion requested that his sentence be vacated pursuant to Ratzlaf, the district court did not address whether McNamara could retroactively take advantage of the substantive rule announced in Ratzlaf. Because we believe that a more thorough discussion of Ratzlaf s retroactive application to McNamara’s appeal would be dispositive, we remand this issue to the district court for further proceedings.
III.
For the foregoing reasons, we reverse the district court’s order, reinstate McNamara’s sentence, and remand the case to the district court for further consideration of the retroactive application of the substantive rule in Ratzlaf.
REVERSED AND REMANDED.
Notes
. Bound by Rogers, the district court submitted an instruction on willfulness to the jury. Neither *516 the Government nor McNamara's trial counsel objected to the instruction or brought Ratzlaf to the court’s attention.

Prior to McNamara's trial, nine other circuits had issued opinions in accord with our holding in
Rogers. See United States v. Scanio,
