Appellant Viterbo Hernandez, Jr. (“Hernandez”) appeals the district court’s denial of his federal habeas petition. In his petition, Hernandez argued, among other things, that the district court’s failure to warn him that his federal term of imprisonment would run consecutive to his anticipated state sentence rendered his federal guilty plea involuntary. We granted Hernandez a certifícate of appealability as to that issue only. Finding no error, we affirm.
BACKGROUND
On November 9, 1993, while in the custody of the State of Texas awaiting trial on charges of distribution of marijuana, Hernandez was indicted for conspiracy to possess with intent to distribute the same marijuana in violation of 21 U.S.C. §§ 841 & 846. On December 6, 1993, a magistrate judge, via writ of habeas corpus ad prosequendum, ordered Hernandez’s transfer into federal custody. On April 22, 1994, pursuant to a plea agreement with the government, Hernandez pled guilty to the federal charge in district court. The district court, on September 16, 1994, sentenced Hernandez to 188 months’ imprisonment followed by five years’ supervised release. The court did not indicate whether Hernandez’s federal term of imprisonment was to run concurrent with or consecutive to any forthcoming state term of imprisonment. Hernandez was thereafter transferred into state custody, where, on October 5, 1994, pursuant to another plea agreement, he pled guilty to the pending state charges. The state court subsequently sentenced Hernandez to a 20-year term of imprisonment to run concurrent with his federal term.
Sometime thereafter, Hernandez discovered that he was not receiving credit against his federal term of imprisonment for time served in state prison. On August 26, 1996, Hernandez moved the federal district court for an order that would make his federal sentence run concurrent with his state sentence; in the alternative, Hernandez sought an order delivering him into federal custody so that he could begin his federal term of imprisonment. Hernandez’s motion was denied November 5, 1996.
On February 26,1997, Hernandez filed a motion to vacate, set aside, or correct his sentence under 28 U.S.C. § 2255. In a subsequent supporting brief, and for the first time in federal court, Hernandez argued that his state-court attorneys reached an agreement with state and federal prosecutors, the substance of which was that, in exchange for his guilty pleas, Hernandez would serve his federal term of imprisonment while his state term ran concurrently. Hernandez argued that his attorneys’ failure to advise him that he could receive a consecutive federal sentence constituted ineffective assistance of counsel. Hernandez also argued that the district court’s failure to warn him that his federal sentence might run consecutive to his state sentence rendered his federal plea involuntary. He contended that had he known of this possibility, he would not have pled guilty to the federal charges.
In support of his petition, Hernandez offered the affidavit of state prosecutor Susan Brown, who stated that she “had *254 numerous discussions” with Hernandez’s state-court attorneys and federal prosecutors. Brown stated that “all parties came to an agreement” that Hernandez would be permitted to serye his federal sentence while his state sentence ran concurrently. She further stated that state prosecutors were advised that, to effectuate the agreement, Hernandez had to enter his federal plea first and that, to this end, entry of Hernandez’s state plea was continued several times. Hernandez also offered the affidavit of one of his state-court attorneys, Aron Pena, who stated that it was the “understanding of everyone concerned” that Hernandez would be permitted to receive credit against his state sentence while serving his federal term of imprisonment. 2
On August 28, 1998, the district court concluded that, under the terms of Hernandez’s federal plea agreement, all issues raised in his § 2255 petition were waived with one exception: whether the court’s failure to warn Hernandez that his federal sentence would run consecutive to his state sentence rendered his federal plea involuntary. As to that issue alone, the district court ordered an evidentiary hearing, which was conducted December 1, 1998.
At the hearing, Hernandez restated the terms of the purported agreement between his state-court attorneys and state and federal prosecutors. Hernandez admitted that his federal plea agreement was silent as to whether his federal sentence would run consecutive to or concurrent with his state sentence. He also acknowledged that he had no discussions with his federal-court attorney, Ron Moody, concerning the alleged sentencing agreement. Further, the parties stipulated that Moody had no knowledge of any agreement that would have Hernandez’s federal sentence run concurrent with his state sentence. Hernandez’s other state-court attorney, Antonio Balderas, testified that he did not remember whether he discussed the purported sentencing scheme with federal prosecutors. Likewise, federal prosecutor Mark Frazier testified that he remembered having only vague discussions with state prosecutors and Hernandez’s state attorneys concerning the possibility of a concurrent sentence.
On December 22, 1998, the district court denied Hernandez’s § 2255 motion, finding that the federal government made no promises with respect to Hernandez’s federal term of imprisonment. That day, the district court entered final judgment; Hernandez’s timely request for a certificate of appealability (“COA”) was later denied. We granted Hernandez a COA solely on the issue of whether the “district court’s failure to inform him that his state and federal sentences might run consecutively” rendered his guilty plea involuntary.
DISCUSSION
I.
The validity of a guilty plea is a question of law we review de novo.
See United States v. Amaya,
The district court’s authority (or lack thereof) to order consecutive or concurrent terms of imprisonment is described in 18 U.S.C. § 3584. We have not before considered whether a defendant must be advised of § 3584’s effect. Prior to September 1, 1987 (§ 3584’s effective date), 18 U.S.C. § 3568 required that a federal term of imprisonment run consecutive to any other sentence to which a defendant was subject.
4
In
United States v. Myers,
The Ninth Circuit, however, stood alone in requiring that a defendant be advised of § 3568’s effect.
Cobb v. United States,
Likewise, the Third Circuit in
Kincade v. United States,
*256 [Consequences no matter how unpalatable which are not related to the length or nature of the federal sentence cannot be considered direct consequences. In the instant case, section 3568 had no effect whatever upon the length of the federal sentence. The statute did operate to increase the length of Kincade’s overall incarceration, but not by modifying his federal punishment.
Id.
at 909 (footnote omitted). We have several times reached the same result as the Third and Fourth Circuits with respect to § 3568, though our reasoning was consistently less expressive.
See Barbee v. Ruth,
II.
We conclude that the effect of 18 U.S.C. § 3584 is not a consequence of which a defendant must be advised before a guilty plea may be accepted. Section 3584 provides, in relevant part: ■
Imposition of concurrent or consecutive terms. — If multiple terms of imprisonment are imposed on a defendant at the same time, or if a term of imprisonment is imposed on a defendant who is already subject to an undischarged term of imprisonment, the terms may run concurrently or consecutively....
18 U.S.C. § 3584(a). Although the plain language of § 3584 suggests that the district court is without discretion to order that a federal term of imprisonment run concurrent with a yet-to-be-imposed state sentence, we have found to the contrary.
See United States v. Brown,
Moreover, were we to follow the circuits that have concluded that a district court has no discretion to order that a federal sentence run concurrent to a state sentence unless the latter has already been imposed,
5
we would, following the persuasive reasoning of
Cobb
and
Kincade
and our own precedents under § 3584’s predecessor, arrive at the same result. As discussed above, the Fourth Circuit in
Cobb
and the Third Circuit in
Kincade
held that the district court need only advise a defendant of consequences that affect his federal sentence. Thus, the application of a no-discretion construction of § 3584, the effect of which would be that the federal
*257
sentence would run consecutive to a later-imposed state sentence, would not affect the length of defendant’s federal term of imprisonment and therefore is not a consequence of which defendant must be warned.
See United States v. Parkins,
Hernandez urges us to follow the Ninth Circuit’s opinion
United States v. Neely,
CONCLUSION
For the foregoing reasons, the judgment of the district court is AFFIRMED. 6
Notes
. In early 1997, Hernandez sought relief in state court, and on March 3, 1998, with the assistance of state prosecutors, an order of dismissal was issued with respect to the state charges. Thereafter, having spent approximately five years in state prison, Hernandez was delivered into federal custody to begin his federal sentence.
. The terms "voluntary” and "knowing” are frequently used interchangeably, although, strictly speaking, the terms embody different concepts. Compare 1A Charles Alan Wright, Federal Practice and Procedure § 172, 142-44 (3d ed.1999)(slatíng a plea of guilty is not voluntary if it is induced by threats, misrepresentation, unfulfilled promises, or promises of an improper nature), with id. § 173, 171-73(stating that a plea is not knowing unless, among other things, defendant understands "what the maximum possible penalty is, including any potential fine and the effect of any special parole or supervised release term”).
. Section 3568 provided, in relevant part:
"The sentence of imprisonment of any person convicted of an offense shall commence to run from the date on which such person is received at the penitentiary, reformatory, or jail for service of such sentence....”
.
See Romandine v. United States,
. Having found that Hernandez’s plea was validly entered, we need not address the government's contention that Hernandez waived his right to challenge his plea.
