Defendant-Appellant Angelica Vitug appeals from her conviction of a total of fourteen counts of visa fraud, 18 U.S.C. § 1546, making false statements to an agency of the United States, 18 U.S.C. § 1001, mail fraud, 18 U.S.C. § 1341, and conspiracy to commit those offenses, 18 U.S.C. § 371, before the United States District Court for the Southern District of New York (Kimba M. Wood, Judge). Vi-tug contends that venue was not properly laid in the Southern District of New York with respect to ten of the substantive counts for which she was convicted. 1 We agree as to counts Six through Nine for visa fraud, and counts Eighteen and Twenty-One for mail fraud; accordingly, we vacate Vitug’s conviction as to those counts. We affirm as to the remaining challenged counts. We remand for further proceedings.
BACKGROUND
Vitug, an endocrinologist, and her co-defendant, Silverio Ramirez, an immigration lawyer, were charged on October 17, 2002 with a variety of offenses stemming from their efforts to obtain fraudulent visas for Ramirez’s clients. The indictment, *137 filed in the Southern District of New York, alleged that Ramirez and Vitug falsely represented to the Immigration and Naturalization Service (“INS”) and the United States Department of Labor (“U.S.DOL”) that Ramirez’s clients would have jobs in the United States with sponsoring employers. Vitug allegedly participated in the scheme by submitting documents to the U.S. DOL and INS representing that her medical practice would employ Ramirez’s clients in jobs that did not exist. Ramirez and Vitug were tried together, and on December 17, 2002, they were convicted on all counts of the indictment. On April 23, 2003, the District Court sentenced Vitug principally to five months’ imprisonment, to be followed by three years’ supervised release. Vitug has completed serving her term of imprisonment and is presently serving her term of supervised release.
Viewing the facts in the light most favorable to the government,
see United States v. Delia,
In February 1997, Ramirez filed with the INS four Form 1-129 Petitions and attachments, certifying that Vitug’s employer, Brooklyn Medical Group (“BMG”), would hire four of Ramirez’s clients to work as “Public Health Educators” at BMG. Vitug signed the Form 1-129 Petitions as well as supporting documents stating that she was a “Founding Partner” of BMG and that BMG currently employed a “Public Health Educator (Diabetes Educator).” The evidence at trial established that Vitug was not a founding partner of BMG, that BMG had never employed a “Public Health Educator,” and that Vitug lacked hiring authority. The evidence also showed that Vitug signed the 1-129 Petitions in New Jersey and that they were filed with an INS branch office in Vermont. Included among the attachments to the 1-129 Petitions were LCA forms that Vitug had previously signed in New Jersey and sent to the Manhattan office of the U.S. DOL for approval.
The second type of fraud involved the submission of false Form ETA-750 applications to the U.S. DOL. Form ETA-750s enable aliens to obtain visas that permit them to remain in the United States indefinitely. See 8 U.S.C. § 1182(a)(5)(A). These visas, too, require sponsorship by an American employer, and the sponsoring employer must show that efforts were made, unsuccessfully, to recruit American citizens for the specific position to be filled *138 by the alien. Red 15 The employer submits a Certified Job Notice and a Recruitment Report to prove that recruitment efforts were made.
In May 1997 and December 1999, Vitug signed and submitted to the U.S. DOL two Form ETA-750s, a Certified Job Notice, and a Recruitment Report, on behalf of two of Ramirez’s clients who would purportedly work as a “Controller” and an “Office Manager” in Vitug’s private New Jersey medical practice, which was curiously located in Ramirez’s New Jersey law office. Testimony by Ramirez’s secretary called these positions into doubt, and evidence indicated that one of these individuals never actually worked for Vitug, while the other worked for her as a chauffeur on Saturdays. Moreover, Ramirez’s secretary testified that, although an advertisement was placed in a newspaper for one of the positions, she overheard Ramirez tell Vitug, in substance, that this step was pretextual and that she should look for flaws to disqualify applicants. The Form ETA-750s, the Certified Job Notice, and the Recruitment Report were initially filed with the New Jersey Department of Labor (“N.J.DOL”), which later forwarded the documents to the U.S. DOL’s Manhattan office. 3
At the close of the government’s case, Vitug moved to dismiss under Rule 29, arguing, among other things, that venue did not properly lie in the Southern District of New York for certain counts. See Fed.R.Crim.P. 29. The District Court initially reserved, but then denied, the motion when it was renewed at the close of the evidence, holding that “[v]iewed in the light most favorable to the government, a preponderance of the evidence clearly demonstrates that essential elements of the conduct constituting the charged offenses occurred in the Southern District of New York, notwithstanding the fact that some essential elements may also have occurred elsewhere.” This appeal ensued.
DISCUSSION
Both the Sixth Amendment and Federal Rule of Criminal Procedure 18 require that defendants be tried in the district where their crime was “committed.” U.S. Const. amend. IV, Fed. R.Crim.P. 18;
see also
U.S. Const, art. iii, § 2, cl. 3. When a federal statute defining an offense does not specify how to determine the location where the crime was committed, “[t]he
locus delicti
must be determined from the nature of the crime alleged and the location of the act or acts constituting it.”
United States v. Cabrales,
*139
When a crime consists of a single, non-continuing act, the proper venue is clear: The crime “is ‘committed’ in the district where the act is performed.”
United States v. Beech-Nut Nutrition Corp.,
Except as otherwise expressly provided by enactment of Congress, any offense against the United States begun in one district and completed in another, or committed in more than one district, may be ... prosecuted in any district in which such offense was begun, continued, or completed. 4
Although the Supreme Court has recognized Congress’s power to define offenses as continuing, it has been wary of extending that label too broadly.
See United States v. Johnson,
The government has the burden of proving that venue is proper.
Beech-Nut,
*140
Vitug argues that the District Court erred in finding that she could be prosecuted in the Southern District of New York for several charges of visa fraud (counts Six through Nine), making false statements (counts Eleven through Fourteen), and mail fraud (counts Eighteen and Twenty-One). Because “venue must be proper with respect to each count,” we may conclude that venue was proper as to some counts but not as to others.
Beech-Nut,
A. Visa Fraud (Counts 6-9)
Counts Six through Nine charged Vitug under 18 U.S.C. § 1546 with subscribing as true and presenting a fraudulent “Form 1-129 Petition ... and attachments” for four of Ramirez’s clients on the “approximate date” of February 7, 1997. As the Supreme Court has said, the first step in a venue inquiry is to “identify the conduct constituting the offense.”
Rodriguez-Moreno,
[w]hoever knowingly makes under oath, or ... knowingly subscribes as true, any false statement with respect to a material fact in any application, affidavit, or other document required by the immigration laws or regulations prescribed thereunder, or knowingly presents any such application, affidavit or other document which contains any such false statement or which fails to contain any reasonable basis in law or fact [will be subject to specified penalties].
(emphases added). Here, the verbs of the statute exhaustively identify the conduct constituting the offense. The statute proscribes the making of, or subscribing to, false statements under oath, as well as the presentation of documents containing such statements. Accordingly, venue would be proper if any of these “essential conduct elements” occurred in the Southern District of New York.
Rodriguez-Moreno,
The evidence at trial showed that Vitug signed the 1-129 Petitions in New Jersey and that they were filed, with attachments, at an INS branch office in Vermont. Vi-tug thus contends that while venue for Counts Six through Nine would have been proper in New Jersey or Vermont, she could not be prosecuted in the Southern District of New York.
The government responds that because at least one of the attachments to each of the Form 1-129 Petitions was sent to the Manhattan branch of the U.S. DOL for approval before being returned to New Jersey for inclusion as attachments to the Form 1-129 Petitions that were filed in Vermont, venue was proper in the Southern District of New York. The government put forth evidence at trial showing that Vitug had previously submitted four LCA forms to the Manhattan U.S. DOL. 5 Moreover, a government witness testified that INS adjudicators review and rely upon LCA forms in deciding whether to approve a Form 1-129 Petition. Based on this evidence, the government argues that a rational juror could have concluded by a preponderance of the evidence that venue was proper since documents that were later appended to the Form 1-129 package were presented and acted upon in the Southern District of New York.
We disagree. First, the counts in question specifically charged visa fraud in connection with the submission of the Form I-129 packages in Vermont. Vitug was not
*141
charged in connection with assembling the forms prior to their submission. Even assuming
arguendo
that steps taken in compiling the Form 1-129 packages could have given rise to a violation of the visa fraud statute, the issue is not before us since the government did not charge Vitug with violating the statute on that basis or argue that theory at trial. Vitug’s case closely parallels
Beechr-Nut.
There, the defendants were charged under the Federal Food, Drug, and Cosmetic Act with “[t]he introduction or delivery for introduction into interstate commerce of any food ... that is adulterated or misbranded.” 21 U.S.C. § 331(a). Although they were prosecuted in the Eastern District of New York, their only connections with that venue were that they had placed telephone orders for adulterated apple juice concentrate to suppliers there and had mailed the suppliers confirmations of these orders.
Beech-Nut,
As in
Beechr-Nut,
Vitug’s act of sending the LCA forms to the Manhattan branch of the U.S. DOL prior to assembling her Form 1-129 package and submitting it to Vermont was “preparatory to the offense,” not part of it.
Beech-Nut,
Beech-Nut
makes clear that even if we were to treat visa fraud as a continuing offense under 18 U.S.C. § 3237(a), the result would be the same. As we explained, “[tjhough § 3237 traces an offense from inception to completion, its thrust is entirely forward-looking; it contains no retrospective provision establishing venue in a district in which the defendant performed only acts that preceded the inception of the offense.”
Beech-Nut,
B. Making False Statements (Counts 11-14)
Vitug was charged in Counts Eleven through Fourteen with making false statements under 18 U.S.C. § 1001 by presenting to the U.S. DOL two Form ETA-750 petitions, a Recruitment Report, and a Certified Job Notice, all of which contained false statements. 18 U.S.C. § 1001(a) provides, inter alia, that:
whoever, in any matter within the jurisdiction of the executive, legislative, or judicial branch of the Government of the United States knowingly and willfully ... makes or uses any false writing or document knowing the same to contain any materially false, fictitious, or fraudulent statement or entry [shall be subject to certain delineated punishments],
(emphasis added). It is thus unlawful under § 1001 to make or use false statements in matters within the jurisdiction of the United States government. The evidence at trial established that each of the documents referenced in Counts Eleven through Fourteen contained materially false statements, that they were initially filed with the N.J. DOL, and that the N.J. DOL ultimately forwarded them to the U.S. DOL in Manhattan for processing.
Vitug argues that because she made the false statements in New Jersey, where she filed the documents, venue did not lie in the Southern District of New York.
United States v. Candella,
Our case is congruent with
Candella.
Although Vitug filed the fraudulent documents in New Jersey, they were forwarded to a federal government agency in Manhattan. Vitug seeks to distinguish
Candella
on the ground that the N.J. DOL was not a “mere conduit” of the documents, but rather “had the duty to review and process them and the power to reject or deny them.” Br. for Appellant at 34;
see also
former 20 C.F.R. § 656.20
et seq.
Whether or not the New Jersey agency reviewed the applications, however, the fact is that it forwarded them to the U.S. DOL in the Southern District of New
*143
York. As we said in
Candella,
“[although enough was done in the Eastern District [of New York] to constitute a crime there ... it does not follow that the crime then terminated, and that what transpired in Manhattan was irrelevant for venue purposes.”
Candella,
Under
Saavedra,
our inquiry should not end with finding that venue properly lay because Vitug committed a continuing offense.
Saavedra,
C. Mail Fraud (Counts 18 and 21)
Vitug also challenges venue with respect to two counts of mail fraud under 18 U.S.C. § 1341. That statute provides:
Whoever, having devised or intending to devise any scheme or artifice to defraud ... for the purpose of executing such scheme or artifice or attempting to do so, places in any post office or authorized depository for mail matter, any matter or thing whatever to be sent or delivered by the Postal Service, or deposits or causes to be deposited any matter or thing whatever to be sent or delivered by any private or commercial interstate carrier, or takes or receives therefrom, any such matter or thing, or knowingly causes to be delivered by mail or such carrier according to the direction thereon, or at the place at which it is directed to be delivered by the person to whom it is addressed, any such matter or thing [shall be subject to certain specified penalties].
18 U.S.C. § 1341 (emphases added). Count Eighteen charged Vitug with mailing to the INS a fraudulent “Form 1-129 Petition ... and attachments” — the same package that formed the basis for the charges of visa fraud in Counts Six through Nine. Count Twenty-One charged Vitug with mailing a Recruitment Report to the N.J. DOL, which was forwarded on to the U.S. DOL in Manhattan. This was the same document that supported the charge of making false statements in Count Eleven. Because the two counts require different analytical approaches, we consider them separately.
i. Count Eighteen
Here, as in Counts Six through Nine, the Form 1-129 Petition and attachments were mailed from New Jersey to an INS office in Vermont; however, the LCA form, which was one of the attachments, had previously been sent to the Manhattan office of the U.S. DOL for approval. The question is therefore the same as in the earlier counts: Was Vitug’s act of mailing the LCA form into New York merely “preparatory to the offense” of mailing the Form 1-129 Petition and attachments, or was it part of the charged offense?
Beech-Nut,
The government notes that in
Brennan,
we left open the question of whether, after
Rodriguez-Moreno,
venue is proper not only where “the defendant ‘places,’ ‘deposits,’ ‘causes to be deposited,’ ‘takes,’ or ‘receives’ mail, or ‘knowingly causes’ mail ‘to be delivered,’ ” but also “in any district where any aspect of the ‘scheme or artifice to defraud’ was practiced.”
9
Brennan,
The Sixth Amendment speaks in terms of the district where a crime is “committed,” and as the Supreme Court has repeatedly emphasized, the
“locus delicti ...
must be determined from the nature of the crime alleged and the location of the
act
or
acts
constituting it.”
Rodriguez-Moreno,
While a scheme to defraud is certainly one of three essential elements of mail fraud, it is not an essential
conduct
element.
See United States v. Walker,
The view that a fraudulent scheme is not itself proscribed conduct finds further support in the law of double jeopardy. It is well-established that each use of the mails constitutes a separate offense of mail fraud.
See Badders,
For these reasons, we conclude that “having devised or intending to devise a scheme or artifice to defraud,” while an essential element, is not an essential
conduct
element for purposes of establishing venue.
Cf United States v. Pace,
In seeking to extend the reasoning of
Rodriguez-Moreno
to our case, the government overlooks a critical difference between the charged offense here, § 1341, and the charged offense in that case, 18 U.S.C. § 924(c)(1). The question in
Rodriguez-Moreno
was whether the defendant could be prosecuted in New Jersey under § 924(c)(1) when he kidnapped the victim in Texas and carried him through numerous states, including New Jersey, but used a gun only in Maryland.
See Rodriguez-Moreno,
The government would have us conclude that “having devised or intending to devise a scheme or artifice to defraud” under § 1341 is comparable to “during a crime of violence” under § 924(c)(1). But whereas a crime of violence such as kidnaping is an act, and thus may qualify as an essential
conduct
element, for the reasons we have already identified, “having devised or intending to devise a scheme or artifice to defraud” is not. 18 U.S.C. § 1341. Thus, even taking into account the Supreme Court’s instruction that “verbs are [not] the sole consideration in identifying the conduct that constitutes an offense,”
Rodriguez-Moreno,
This conclusion is consistent with the Supreme Court’s admonition that provisions implicating venue are to be narrowly construed.
See Johnson,
Accordingly, Vitug began the offense under Count Eighteen when, on approximately February 7, 1997, she or Ramirez “place[d]” in a mailbox the “1-129 Petition and attachments,” “knowingly causing] them to be delivered” to the INS in Vermont. Having thus defined the conduct constituting the offense of mail fraud, the question is whether the mailing of the LCA form to the Southern District New York was part of the charged offense, or merely preparatory to it.
See Beech-Nut,
*147 ii. Count Twenty-One
Count Twenty-One, which charged Vitug with mail fraud in connection with the Recruitment Report that was mailed to the N.J. DOL and forwarded to the U.S. DOL in Manhattan, presents the same factual predicate as Count Eleven. Vitug argues that venue was not proper in the Southern District of New York because the mailing was “made in New Jersey to the New Jersey Department of Labor.” Br. of Appellant Vitug at 34-35.
The government responds that, as with the counts of making false statements,
Candella
makes venue proper on a continuing offense theory. In order to find that
Candella
applies to Count Twenty-One, however, we would first have to determine whether mail fraud, like making false statements, may qualify as a continuing offense under the first paragraph of § 3237(a).
11
This would require deciding whether mail fraud, too, is “not unitary but instead spans space or time.”
Beech-Nut,
We need not reach this question, however, because the mail fraud statute itself explicitly makes venue proper where the defendant “knowingly causes to be delivered by mail or such carrier according to the direction thereon, or at the place at tohich it is directed to he delivered by the person to whom it is addressed.” 12 18 U.S.C. § 1341 (emphasis added). Here, it is clear that Vitug caused the Recruitment Report to be delivered by mail to the N.J. DOL. The New Jersey agency — “the person to whom [the Recruitment Report was] addressed” — then directed it to be delivered to the U.S. DOL in Manhattan. Under the plain language of the statute, therefore, venue would be proper in the Southern District of New York as to this count provided that Vitug knowingly caused the Recruitment Report to be delivered to Manhattan.
The government asserts in its post-argument letter brief that Vitug “knowingly caused [the Recruitment Report] to be sent to the SDNY for processing and final approval by the U.S. Department of Labor (even though the mailing was reviewed first at the New Jersey Department of Labor before being sent to the U.S. Department of Labor).” However, it does not direct us to anything in the record to support the bald assertion that Vitug had knowledge that the document would be forwarded to Manhattan. The govern
*148
ment has thus failed to meet its burden of proving venue.
See Beech-Nut,
CONCLUSION
For the reasons provided, we AffiRM Appellant’s convictions for Counts Eleven through Fourteen of the indictment, and Vacate her convictions for Counts Six through Nine, Eighteen, and Twenty-One. We Remand for further proceedings in conformity with this opinion.
Notes
. We treat Vitug’s other grounds for appeal, as well as the claims of her co-defendant, in a separate summary order. Defendant-Appellant Ramirez does not join Vitug's venue claims.
. The informal term “H-IB” visa derives from Section 101(a)(15)(H)(i)(b) of the Immigration and Nationality Act, which sets out the requirements for this type of visa. See 8 U.S.C. § 1101(a)(15)(H)(i)(b).
. The documents were first filed with the N.J. DOL pursuant to former 20 C.F.R. § 656.20 et seq., through which the U.S. Secretary of Labor delegated authority to the state departments of labor to carry out the functions described in 8 U.S.C. § 1182(a)(5)(A).
. The second paragraph of § 3237(a) goes on to specify certain types of offenses that are per se continuing:
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.
Id..; see United States v. Brennan,
. Count Ten of the indictment charged Vitug with making false statements by submitting the LCAs to the Manhattan branch of the DOL on the "approximate date" of January 30, 1997. Vitug does not challenge venue as to that count.
. Count Ten indicates that these mailings were made on the “approximate date” of January 30, 1997 — at least one week before the Form 1-129 packages were sent.
. Brooklyn lies within the Eastern District of New York, while Manhattan lies in the Southern District of New York.
. Vitug’s mail fraud offense could only be considered continuing under the first paragraph of 18 U.S.C. § 3237(a), as this Court has held that mail fraud does not qualify as “use of the mails” under the second paragraph of the continuing offense statute.
See Brennan,
. We did not need to answer that question in
Brennan
because "the government [did] not contend that the defendants either devised or executed the fraud in the Eastern District of New York.”
Brennan,
. Moreover, even assuming that devising a scheme sometimes involves conduct beyond mere thought, the statute does not insist that a scheme actually have been devised; it only requires that the defendant “intend[]” to devise a scheme. 18 U.S.C. § 1341.
. After all, it is only when an offense is continuing that venue is properly laid in " ‘the whole area through which force propelled by an offender operates.' ”
Candella,
. The "knowingly causes to be delivered” clause was not in the original mail fraud statute, which was enacted in 1872, but was added to it during an early revision and reenactment. In
