OPINION
Appellant, Fausto Miguel Uribe-Rios, appeals his conviction and sentence under 8 U.S.C. § 1326 for being “found in” the United States without the permission of the Attorney General after having previously been deported for an aggravated felony. Appellant reentered the United States under an alias and was later arrested and convicted by North Carolina authorities for drug trafficking. Upon his release from state prison after a five-year sentence, Appellant was interviewed by federal immigration authorities. During that interview, Appellant revealed his real identity and unauthorized presence in the United States. Eight days later, Appellant was indicted under section 1326. Appellant moved to dismiss the indictment on statute of limitations, venue, and pre-in-dictment delay grounds. After the district court denied the motion, Appellant pleaded guilty and was sentenced. On appeal, Appellant raises the same arguments and also challenges his sentence on Fifth and Sixth Amendment grounds. For the reasons set forth below, we affirm.
I.
Appellant Fausto Miguel Uribe-Rios, a citizen of Mexico, has been deported from the United States on at least five separate occasions in ten years, at least once after having been convicted of an aggravated felony. He unlawfully reentered the United States in 1997 and was subsequently arrested by North Carolina law enforce *350 ment officials for drug trafficking in August 2000.
The record shows that Appellant used over thirty aliases during his time in the United States, including, but not limited to, “Francisco Rios Medina,” “Francisco Uribe-Rios,” “Efrain Gomez-Gonzalez,” “Jose Antonio Bautista Cobos,” “Victor Gomez-Gomez,” “Adolfo Rios Medina,” “Ruben Hureverios,” and “Paco Gomez.” J.A. 175. Following his arrest in 2000, he was prosecuted under the name “Francisco Rios Medina” in Wake County, which is located in the Eastern District of North Carolina. On January 26, 2001, following a trial in North Carolina state court, he was sentenced to six years in state prison.
Although Appellant was initially incarcerated in a facility located in the Eastern District of North Carolina, in December 2004 he was transferred to a different facility located in the Western District of North Carolina where he served the remainder of his state prison term. Before the transfer occurred, federal immigration authorities placed a detainer 1 on Appellant under the name “Francisco MEDINA-Rios.” The detainer, dated May 28, 2004, advised North Carolina officials that an “[ijnvestigation ha[d] been initiated to determine whether this person is subject to removal from the United States.” S.A. l. 2
Upon his release from state prison in the Western District of North Carolina on September 21, 2006, Appellant was immediately taken into custody by the United States Bureau of Immigration and Customs Enforcement (“ICE”). In an interview with ICE agents conducted that same day, Appellant stated that his real name was Fausto Miguel Uribe-Rios, he had previously used the alias “Francisco Rios Medina,” he had previously been deported, and he had not applied to the Attorney General for permission to reenter the United States. Appellant reiterated these statements in a sworn affidavit. J.A. 52-53. ICE agents processed Appellant’s fingerprints at that time, discovering deportation orders and warrants under Appellant’s true name, Fausto Miguel Uribe-Rios, as well as under the aliases “Francisco Uribe-Rios” and “Efrain Gomez-Gonzalez.” It is undisputed that the federal government did not have actual knowledge of Appellant’s presence in this country under his correct name until this time.
Appellant was indicted in the Western District of North Carolina on September 29, 2006, under 8 U.S.C. § 1326 for being “found in” the United States without the permission of the Attorney General after having previously been deported for an aggravated felony. 3 Section 1326 provides in pertinent part:
(a) In general ... any alien who—
(1) has been ... removed or has departed the United States ... and thereafter
(2) enters, attempts to enter, or is at any time found in, the United States, unless ... the Attorney General has expressly consented ...
shall be fined under Title 18, or imprisoned not more than 2 years, or both.
(b) Criminal penalties for reentry of certain removed aliens — Notwithstanding subsection (a) ...
*351 (2) [Any alien] whose removal was subsequent to a conviction for commission of an aggravated felony, such alien shall be fined under such Title, imprisoned not more than 20 years, or both.
8 U.S.C. § 1326.
In the district court, Appellant moved to dismiss the indictment, arguing that the applicable statute of limitations had run, that venue was improper, and that he was prejudiced by pre-indictment delay. The district court rejected Appellant’s arguments and denied the motions to dismiss the indictment.
United States v. Uribo-Rios,
No. 3:06cr395,
Appellant timely appealed his conviction, raising the same statute of limitations, venue, and pre-indictment delay claims raised in the district court below. He also raised a new claim that his sentencing violated his rights under the Fifth and Sixth Amendments because he was sentenced based on past convictions that were neither admitted by him nor proven to a jury beyond a reasonable doubt.
II.
We have jurisdiction under 28 U.S.C. § 1291. Appellant’s arguments turn on questions of law, which we review de novo.
United States v. Woolfolk,
ill.
The parties do not dispute that the applicable statute of limitations is five years. 5 Appellant argues that the statute of limitations began running on January 26, 2001, when he “entered the custody of the State of North Carolina.” Appellant’s Br. at 15. He contends that “[a]t that point, he had been ‘found’ by authorities as required to establish a violation of 8 U.S.C. § 1326.” Id. He notes that at or by this date, he had given his name as “Miguel Uribe-Rios” in state court and had testified in that forum as to his illegal status in the United States. He further emphasizes that “he was in the exclusive control of government authorities” and had been fingerprinted. Id. at 15,18.
To support his statute of limitations argument, Appellant relies heavily on
United States v. Gomez,
In addition to
Gomez,
Appellant cites cases from the Second, Fifth, and Tenth Circuits for the proposition that “for an alien to be ‘found,’ the government must have ‘knowledge of the illegality of his presence, through the exercise of diligence typical of law enforcement authorities.’ ”
United States v. Bencomo-Castillo,
A.
Appellant’s argument that the limitations period began running on January 26, 2001 is unpersuasive for several reasons. At the outset, we note that Appellant cites no evidence in the record showing that on January 26, 2001, federal immigration authorities were aware of his identity and illegal presence in the United States. As Appellant correctly points out, courts interpreting section 1326 have held that “a previously deported alien is ‘found in’ the United States when his physical presence is discovered and noted by the immigration authorities.”
United States v. Reyes-Nava,
Contrary to Appellant’s argument that when he was incarcerated by state officials he was in the custody of “governmental” authorities and therefore “found” under section 1326, courts have routinely held that an alien is “found in” the United States only when
federal,
not state, immigration officials become aware of the alien’s presence and illegal status. In
United States v. Santana-Castellano,
B.
Appellant also relies on Gomez and a theory of constructive knowledge to sup *354 port his statute of limitations argument. His arguments are unavailing in this case for several reasons.
1.
First, we note that the plain text of section 1326 does not support a theory of constructive knowledge. An alien violates 8 U.S.C. § 1326 when the alien “is at any time found in[] the United States” — not when the alien is “found or should have been found” in the country, as Appellant argues. The Seventh Circuit has already rejected a theory of constructive knowledge under section 1326, finding that “when the government ‘should have discovered’ a deportee’s illegal presence in the United States is irrelevant to when the statute of limitations begins to run.”
United States v. Gordon,
2.
Second, even if section. 1326 does countenance a theory of constructive knowledge, we conclude, consistently with other circuit courts, that such a theory does not benefit Appellant. Notably, Appellant cites
no
case in which a court has found that federal immigration authorities had constructive knowledge of an alien’s illegal presence in the United States when the alien concealed his identity through the use of an alias. Although the theory of constructive knowledge imposes upon federal immigration officials a duty to exercise “diligence typical of law enforcement authorities” in ascertaining an alien’s immigration status,
see United States v. Bencomo-Castillo,
In
Bencomo-Castillo,
for example, the Tenth Circuit acknowledged the availability of a constructive knowledge theory under section 1326, but nevertheless affirmed the district court’s determination that federal immigration authorities had “found” an alien only when “an INS agent identified him as a previously deported alien,” and not at an earlier point when state police arrested him, took his fingerprints, and submitted them to the FBI.
[F]or statute of limitations purposes in § 1326 prosecutions, there can be no finding of lack of diligence where it is deception by the alien as to his identity that has caused the government not to have knowledge of his presence. To hold otherwise would be to reward deceit by the alien and to encourage the withholding of information, and so the corruption of the deportation process.
Id. at 52. Like our sister circuits, we decline to employ a theory of constructive knowledge to find that federal immigration officials in this case failed to act with “diligence typical of law enforcement authorities” when Appellant concealed his identity with an alias.
3.
Moreover, Appellant cites no case in which a court has found that federal immigration authorities had constructive knowledge of an alien’s illegal presence in the United States when the alien was in the custody of state, rather than federal, law enforcement officials. As noted above, courts have uniformly declined to find that state officials’ knowledge of an alien’s illegal presence in the United States may be imputed to federal immigration authorities for purposes of determining when the limitations period begins to run. Although Appellant relies heavily on
Gomez
to support his constructive knowledge argument, this reliance is misplaced. In
Gomez,
the alien presented himself to
federal
immigration authorities and provided his real name and fingerprints. As the
Gomez
court noted, “[b]ecause the INS had in its possession Gomez’s fingerprints [under both his alias and his real name], and had access to the FBI facilities for fingerprint comparison, it possessed both the information and the means necessary to determine Gomez’s status as a deported alien.”
*356
There is no evidence in the record to show that, as in
Gomez,
federal immigration authorities had “both the information and the means necessary” to ascertain Appellant’s illegal presence in the United States.
Appellant has failed to show evidence of facts that would support a finding of constructive knowledge as articulated by our sister circuits. Regardless of whether section 1326 countenances a constructive knowledge theory, such a theory is unavailable to Appellant because of his own malfeasance in using an alias and because fundamental principles of dual sovereignty do not allow us to impute the knowledge of state officials to federal officials. Indeed, Appellant urges us to adopt a theory of constructive knowledge unsupported by either the statutory text or case law. We decline to find a lack of diligence “where it is deception by the alien as to his identity that has caused the government not to have knowledge of his presence.”
DeLeon,
Because Appellant has not shown that federal immigration officials discovered his illegal presence in the United States and ascertained that he had reentered after a previous deportation on January 26, 2001, his statute of limitations argument fails.
IV.
Appellant next argues that venue was improper in the Western District of North Carolina because he was “found” in the Eastern District of North Carolina before his involuntary transfer to the
*357
Western District of North Carolina in December 2004. Title 8 U.S.C. § 1329 states that a prosecution for a violation of section 1326 “may be instituted at any place in the United States at which the violation may occur.” Courts have interpreted this provision as placing venue for a section 1326 offense in any district where an alien is “found.”
See United States v. Almendarez,
Appellant argues that he “should have been ‘found,’ at the latest, when federal immigration authorities placed a detainer on him” on June 7, 2004 — before state officials transferred him to another state institutional facility in the Western District of North Carolina. Appellant’s Br. at 22. He cites
United States v. Hernandez-Hernandez,
Hemandez-Hemandez is inapposite to this case. There is no indication that the alien in that case concealed his identity from state and federal law enforcement authorities by using an alias. Nor is there any indication that immigration authorities were not aware of the alien’s identity and immigration status when the detainer was issued. In contrast, the record here shows, at most, that federal immigration authorities had requested a detainer on someone named “Francisco MEDINA-Rios” and that an “[ijnvestigation ha[d] been initiated to determine whether this person [was] subject to removal from the United States.” S.A. 1. Appellant points to nothing in the record to show that when they placed a detainer on Francisco Medina-Rios, federal immigration authorities had actual knowledge of either his real identity or immigration status, let alone both.
Although Appellant makes much of the fact that he was involuntarily present in the Western District when he was found, this argument does not alter our venue analysis. As noted above, section 1329 places venue for a section 1326 violation in any district where the alien is found, with no regard as to whether the alien is in that district voluntarily. The Seventh Circuit has expressed a similar view in
Herrera-Ordones,
holding that “whether an alien was in a particular location by choice has no relevance in venue determinations” because “[v]enue is proper anywhere in the United States, wherever the previously deported and reentered alien is ‘found.’ ”
y.
Appellant also argues that the five years between his state incarceration in 2001 and his federal immigration prosecution in 2006 amounted to an unconstitutionally prejudicial pre-indictment delay. He argues that the delay violated his Fifth *358 Amendment right to due process because it cost him the chance to serve part of his federal and state sentence concurrently.
In
United States v. Marion,
Appellant’s Fifth Amendment due process argument is unavailing because he has failed to establish that pre-indictment delay resulted in the unavailability of any records, witnesses, or other evidence. 7 Instead, his sole argument on appeal is that pre-indictment delay cost him the chance to serve his federal and state sentences concurrently.
We reject this argument for several reasons. First, because there is no right to serve state and federal sentences concurrently, an appellant’s lost chance of doing so cannot be used to establish prejudice for the purposes of challenging pre-indictment delay.
United States v. Ferguson,
Second, we note that the opportunity to serve concurrent sentences does not implicate Appellant’s Fifth Amendment right to a fair
trial. See United States v. Ricketson,
Because Appellant failed to meet his burden of proving that pre-indictment delay actually prejudiced his right to a fair trial, his Fifth Amendment claim fails.
VI.
Finally, Appellant challenges his sentence, arguing that the district court’s consideration of prior convictions, evidence of which was neither alleged in the indictment nor proven to a jury beyond a reasonable doubt, violated his rights under the Fifth and Sixth Amendments.
See Apprendi v. New Jersey,
Appellant concedes that his claim falls within
Apprendi’s
express exception regarding evidence of prior convictions and acknowledges our recent reiteration that “the ‘fact of a prior conviction’ remains a valid enhancement even when not found by the jury.”
United States v. Thompson,
VII.
For the foregoing reasons, the opinion below is
AFFIRMED.
Notes
.A detainer is a mechanism by which federal immigration authorities may request that another law enforcement agency temporarily detain an alien "in order to permit assumption of custody by the Department [of Homeland Security].” See 8 C.F.R. § 287.7(d).
. References to "S.A." are to the Supplemental Appendix submitted by the parties. References to "J.A.” are to the Joint Appendix submitted by the parties.
. The indictment refers specifically to "Sections 1326(a) and (b)(2).” J.A. 6.
. The different spelling of "Uribe-Rios” in the caption appears to be a clerical error in the slip opinion below.
.
See
18 U.S.C. § 3282(a) (catch-all limitations period for non-capital offenses);
see also United States v. Rivera-Ventura,
. Notably, the court transcript refers to both "Francisco Medina [Miguel Uribe-Rios]” and "Miguel Uribe Rios/a.k.a. Francisco Medina.” J.A. 135G, 1351. Although Appellant asserts that he had "given his correct name of Miguel Uribe-Rios in open court and had testified under oath” as to his illegal immigration status and deportability, Appellant’s Br. at 15, *356 the record shows that the prosecution addressed him as “Mr. Medina,” J.A. 1351.
. The district court found, and Appellant has not contested, that Appellant admitted he was "unsure” whether immigration records had been lost and could not identify any witnesses who were no longer available to testify.

Smith v. Hooey,
. Appellant pleaded guilty to illegal reentry under 8 U.S.C. § 1326(a) and (b)(2). The statutory maximum term of imprisonment for that offense is 20 years. 8 U.S.C. § 1326(b)(2). Appellant was sentenced to 70 months imprisonment.
