OPINION OF THE COURT
This appeal presents two questions of first impression. First, we consider whether the general criminal venue provision, 18 U.S.C. § 3238, applies when a defendant commits part of his offense inside the United States. Second, we determine whether 18 U.S.C. § 2423(c) and (f)(1), which together criminalize noncommercial illicit sexual conduct outside the United States, is a valid exercise of Congress’s power under Article I, Section 8, Clause 3 of the United States Constitution (the Foreign Commerce Clause).
I
On November 25, 2005, Thomas Pendleton boarded a plane in New York City and flew to Hamburg, Germany. Six months after his arrival in Germany, Pendleton sexually molested a fifteen-year-old boy. German authorities arrested Pendleton, and a jury in Hamburg found him guilty of “engaging in sexual acts with a person incapable of resistance.” After serving nineteen months in a German prison, Pendleton returned to the United States, where he was arrested and indicted by a federal grand jury in the District of Delaware on one count of engaging in noncommercial illicit sexual conduct in a foreign place, in violation of 18 U.S.C. § 2423(c) and (f)(1).
Adopted in 2003 as part of the Prosecutorial Remedies and Other Tools to End the Exploitation of Children Today Act (the PROTECT Act), § 2423(c) provides: “Any United States citizen or alien admitted for permanent residence who travels in foreign commerce, and engages in any illicit sexual conduct with another person shall be fined under this title or imprisoned not more than 30 years, or both.” The statute defines “illicit sexual conduct” in two ways: (1) “a sexual act (as defined in section 2246) with a person under 18 years of age that would be in violation of chapter 109A if the sexual act occurred in the special maritime and territorial jurisdiction of the United States;” or (2) “any commercial sex act (as defined in section 1591) with a person under 18 years of age.” 18 U.S.C. *302 § 2423(f). Pendleton was indicted under the first subpart of § 2423(f), which criminalizes noncommercial sex with a minor.
Pendleton moved to dismiss the indictment, challenging Congress’s authority to regulate noncommercial activity outside the United States under the Foreign Commerce Clause and the Due Process Clause of the Fifth Amendment. The District Court denied Pendleton’s motion, holding that 18 U.S.C. § 2423(c) was a valid exercise of Congress’s power to regulate the “channels” of foreign commerce.

See United States v. Clark,
Following a two-day jury trial, Pendleton was convicted of engaging in illicit sexual conduct in Germany in violation of 18 U.S.C. § 2423(c), and he was sentenced to thirty years in prison.

At the close of the Government’s case, Pendleton moved for judgment of acquittal under Federal Rule of Criminal Procedure 29(a), claiming that he should have been tried in the Eastern District of New York. The District Court denied the motion, holding that venue was proper in the District of Delaware because Pendleton was arrested there following his return to the United States.
United States v. Pendleton,
Pendleton timely appealed the District Court’s judgment of sentence and seeks reversal for two reasons: (1) venue was improper in the District of Delaware; and (2) the “noncommercial” prong of 18 U.S.C. § 2423(c) is facially unconstitutional. We consider each argument in turn.
II
Jurisdiction lies over Pendleton’s appeal under 28 U.S.C. § 1291 and 18 U.S.C. § 3582, and we exercise plenary review over the District Court’s venue determination.
United States v. Perez,
As a defendant in a criminal trial, Pendleton has a constitutional right to
*303
be tried in the district where his crime was committed.
Id.
at 329 (citing U.S. Const. amend. VI and U.S. Const, art. Ill, § 2, cl. 3). Congress may fix jurisdiction in any district where a “crucial element” of the crime is performed.
Id.
When Congress has “not indicate[d] where it considers] the place of committing the crime to be,” we determine jurisdiction “from the nature of the crime alleged and the location of the act or acts constituting it.”
United States v. Rodriguez-Moreno,
Although the PROTECT Act contains no express venue provision, Pendleton argues that Congress fixed venue for all crimes involving “transportation in foreign commerce” only in those districts where foreign travel commenced. For this proposition, Pendleton cites 18 U.S.C. § 3237(a), which reads in relevant part:
Any offense involving the use of the mails, transportation in interstate or foreign commerce, or the importation of an object or person into the United States is a continuing offense and, except as otherwise expressly provided by enactment of Congress, may be inquired of and prosecuted in any district from, through, or into which such commerce, mail matter, or imported object or person moves.
Because he boarded the plane to Germany in the Eastern District of New York, Pendleton claimed jurisdiction would have been proper only in that district. The District Court disagreed, writing that “the PROTECT Act contains no directive as to the appropriate venue for the prosecution of those charged under its provisions.” Consequently, the Court relied on
Rodriguez-Moreno’&
two-pronged approach to determine venue in this case.
Pendleton,
Contrary to Pendleton’s argument, § 3237(a) does not include a mandatory venue provision. Rather, the statute instructs that offenses involving interstate or foreign transportation
“may be
inquired of and prosecuted ... in the district from ... which such commerce ... moves.”
Id.
(emphasis added). Accordingly, the Government is not statutorily barred from prosecuting Pendleton in another district if it can show that a portion of his offense was committed there. Moreover, the Constitution does not “ ‘command a single exclusive venue.’ ”
United States v. Goldberg,
Where, as here, Congress has not designated the venue in the relevant criminal statute, we employ the two-pronged approach set forth in
Rodriguez-Moreno. See
Any United States citizen or alien admitted for permanent residence who travels in foreign commerce, and engages in any illicit sexual conduct with another person *304 shall be fined under this title or imprisoned not more than 30 years, or both.
18 U.S.C. § 2423(c). The crime of conviction thus comprises three elements: (1) being a United States citizen or permanent resident; (2) traveling in foreign commerce; and (3) engaging in illicit sexual conduct.
See Clark,
Of these three elements, we agree with the District Court that “engaging in illicit sexual conduct” is the most critical to § 2423(c). Indeed, the title of the offense' — “Engaging in Illicit Sexual Conduct in Foreign Places” — describes only this conduct. Moreover, while travel in foreign commerce is an element of § 2423(c), the crime itself is not complete until a person engages in illicit sex. In this regard, § 2423(c) is unlike the crime of “[tjravel with intent to engage in illicit sexual conduct,” defined in § 2423(b), which is complete as soon as one begins to travel with the intent to engage in a sex act with a minor.
See United States v. Bredimus,
Because the crux of Pendleton’s offense was “committed ... out of the jurisdiction of any ... district,” the District Court held that 18 U.S.C. § 3238 was the controlling venue provision. Section 3238 provides that an offense “begun or committed” outside the United States “shall be [prosecuted] in the district in which the offender ... is arrested.” Pendleton argues that § 3238 does not apply to him because part of his offense occurred in the Eastern District of New York and the title of § 3238 describes only those “offenses not committed in
any
district.”
Id.
(emphasis added). This, argument has some persuasive force, as two of our sister courts of appeals have held that “[s]ection 3238 does not apply unless the offense was committed entirely on the high seas or outside the United States.”
United States v. Pace,
On the other hand, the Courts of Appeals for the Fourth and Fifth Circuits have held that § 3238 applies even when some of a defendant’s offense conduct takes place in the United States.
See, e.g., United States v. Levy Auto Parts,
Although the title of § 3238 includes only “offenses not committed in any district,” it is a “well-settled rule of statutory interpretation that titles and section headings cannot limit the plain meaning of statutory text where that text is clear.”
M.A. ex rel. E.S. v. State-Operated Sch. DisL,
Here, although Pendleton’s offense began when he initiated foreign travel by boarding a plane bound for Germany in the Eastern District of New York, he “committed” the offense when he engaged in an illicit sex act in Germany. Because Pendleton’s criminal conduct was “essentially foreign,”
Levy Auto Parts,
Ill
Having found that venue was proper in Delaware, we turn to Pendleton’s substantive claim, namely, his assertion that the “noncommercial prong” of 18 U.S.C. § 2423(c) is facially unconstitutional. Pendleton’s constitutional claim is subject to plenary review.
United States v. Singletary,
A
The Constitution authorizes Congress “to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes.” U.S. Const. art. I, § 8, cl. 3. In the early days of the Republic, the Supreme Court defined “commerce” broadly to include “every species of commercial intercourse” between two parties.
Gibbons v. Ogden,
The three-category framework outlined in
Lopez
and
Morrison
applies, on its face, to statutes enacted pursuant to the Interstate Commerce Clause. The Supreme Court has yet to determine whether this framework applies to cases involving Congress’s power to regulate pursuant to the Foreign Commerce Clause. Early opinions of the Court suggest that the three sub-parts of the Commerce Clause should be interpreted similarly. Notably, in
Gibbons v. Ogden,
Chief Justice Marshall'suggested that “commerce, as the word is used in the constitution, is a unit ... [and] it must carry the same meaning throughout the sentence, and remain a unit, unless there be some plain intelligible cause which alters it.”
Notwithstanding Chief Justice Marshall’s statement in
Gibbons,
the three subclauses of Article 1, § 8, cl. 3 have acquired markedly different meanings over time. Whereas the Interstate Commerce Clause has been constrained by state sovereignty concerns,
see, e.g., Morrison,
The Foreign Commerce Clause likewise has “followed its own distinct evolutionary path,”
Clark,
Although jurisprudence on the so-called “dormant” Foreign Commerce Clause is well-developed, “[cjases involving the reach of ... congressional authority to regulate our citizens’ conduct abroad are few and far between.”
Clark,
The Government urges us to adopt the Ninth Circuit’s approach to the Foreign
*308
Commerce Clause. Although we agree with
Clark
that the Interstate Commerce Clause developed to address “unique federalism concerns” that are absent in the foreign commerce context, we are hesitant to dispose of Lopez’s “time-tested” framework without further gúidance from the Supreme Court.
See id.
at 1119 (Ferguson, J., dissenting). The Supreme Court has not yet held that Congress has greater authority to regulate activity outside the United States than it does within its borders; in fact, the language used to describe its extraterritorial jurisdiction is quite similar to that used in
Lopez. See, e.g., Hartford Fire Ins. Co. v. California,
B
“[T]he authority of Congress to keep the channels of interstate commerce free from immoral and injurious uses has been frequently sustained, and is no longer open to question.”
Heart of Atlanta Motel, Inc. v. United States,
In
United States v. Tykarsky,
we held that 18 U.S.C. § 2423(b), which criminalizes interstate travel with intent to engage in illicit sexual conduct with a minor, is a valid exercise of Congress’s power to regulate the channels of commerce.
In
United States v. Shenandoah,
we upheld portions of the Sex Offender Registration and Notification Act (SORNA), 18 U.S.C. § 2250(a)(1) and (2) and 42 U.S.C. § 14072(i)(l), making it illegal for a sex offender to fail to properly register after traveling in interstate commerce.
*310
Nevertheless, SORNA was specifically enacted to address “one of the biggest problems in our current sex offender registry,” 152 Cong. Rec. S8012-14 (daily ed. July 20, 2006),
The same rationale applies to Pendleton’s case. Just as SORNA’s “failure to report” provision was intended to prevent convicted sex offenders from “us[ing] the channels of interstate commerce in evading a State’s reach,”
Carr,
*311
Members of Congress also expressed concern that § 2423(b) would not adequately deter child-sex tourists because prosecutors were having an “extremely difficult” time “proving intent in such cases.” 148 Cong. Rec. 3884 (stating that intent is particularly “difficult to prove without direct arrangement booked through obvious child sex-tour networks.”). This, in turn, “ereat[ed] a loophole in the law for men who go abroad to have sex with minors, which in the United States is considered statutory rape.”
Id.
Section 2423(c) was enacted to close the enforcement gap and to “send a message to those who go to foreign countries to exploit children that no one can abuse a child with impunity.”
Id.
Thus, as it did with SORNA, Congress enacted § 2423(c) to regulate persons who use the channels of commerce to circumvent local laws that criminalize child abuse and molestation. And just as Congress may cast a wide net to stop sex offenders from traveling in interstate commerce to evade state registration requirements, so too may it attempt to prevent sex tourists from using the channels of foreign commerce to abuse children.
Id.; Clark,
In sum, because the jurisdictional element in § 2423(c) has an “express connection” to the channels of foreign commerce,
Morrison,
IV
For the foregoing reasons, we will affirm the District Court’s judgment of conviction and sentence.

reprinted in
2003 U.S.C.C.A.N. 683, 686 (Apr. 9, 2003). However, the language of § 2423(c) was adopted verbatim from an earlier bill — the Sex Tourism Prohibition Improvement Act of 2002 — which relied on the Foreign Commerce Clause as the basis for its constitutional authority.

holding that no due process violation occurs when Congress criminalizes conduct abroad that is “condemned universally by law-abiding nations.”

U.S. at 225 (Johnson, J., concurring) (quoting the preamble of James Madison's draft resolution at the Virginia Ratifying Convention, stating that “the relative situation of the United States has been found, on trial, to require uniformity in their commercial regulations, as the only effectual policy for obtaining, in the ports of foreign nations, a stipulation of privileges reciprocal to those enjoyed by the subjects of such nations in the ports of the United States”);

. The Ninth Circuit in
Clark
claims to borrow this "rational basis” test from the Supreme Court's holding in
Gonzales v. Raich. See
The "rational basis” standard articulated by the Ninth Circuit in
Clark
does not consider any of these factors. Rather, its open-ended inquiry seems to borrow more heavily from the Supreme Court’s
pre-Lopez
jurisprudence, which held that a court’s "investigation ... end[s]” once it determines that "legislators ... have a rational basis for finding a chosen regulatory scheme necessary to the protection of commerce.”
Katzenbach v. McClung,
. In this respect, SORNA's “failure to register” provision is similar to the federal felon-in-possession law, 18 U.S.C. § 922(g), enacted pursuant to Congress’s authority under the Commerce Clause. Section 922(g) makes it unlawful for a felon to "possess in or affecting commerce, any firearm or ammunition ... which has been shipped or transported in
*310
interstate or foreign commerce.” In
United States v. Singletary,
we held that the transport of a weapon through the channels of interstate commerce — however remote in the distant past — provides a sufficient jurisdictional nexus to satisfy
Lopez's
first prong.
. Having found that the statute is constitutional under the first prong of
Lopez,
we need not address Pendleton’s contention that § 2423(f)(1) does not survive
Morrison's
stringent "substantial effects” test.
