MEMORANDUM

Jesse Lee Vardaro appeals his conviction under 18 U.S.C. § 2250 (a) for failure to register as a sexual offender under the Sex Offender Registration and Notification Act (“SORNA”). We have jurisdiction under 28 U.S.C. § 1291 , and we affirm.

Under SORNA, an individual who has been convicted of a sex offense must register, and keep'the registration current, “in each jurisdiction where the offender resides, where the offender is an employee, and where the offender is a student.” 42 U.S.C. § 16913 (a). SORNA also requires that a:

Id. § 16913(c).

The district court found that Vardaro, who had registered as a sex offender in Michigan, was ' an employee of Dawson Geophysical in Montana from October 28, 2007, until early January 2008, and that he resided in Montana during that same approximate period. Accordingly, the district court concluded that Vardaro was required to register as a sex offender in Montana.

On appeal, Vardaro concedes that he is an individual .required to register under SORNA, that he traveled in interstate commerce, and that he knowingly failed to update his registration. He argues that the district court improperly concluded that he resided in Montana for purposes of SORNA and was therefore required to register in that state. Importantly, however, he fails to challenge the district court’s finding that he was employed in Montana and therefore had an obligation, independent of his residence status, to register under SORNA. Because Vardaro had an obligation under SORNA to register in the jurisdiction in which he was employed and because he does not challenge the district court’s findings that he was employed in Montana and that he failed to register there, his conviction must be affirmed.

AFFIRMED.
