28 C.F.R. § 72.7
(2) Special rules for certain cases. The following special requirements apply:
(b) Periodic in-person verification. A sex offender must appear in person, allow the jurisdiction to take a current photograph, and verify the information in each registry in which the offender is required to register. In carrying out the required verification of information in each registry, the sex offender must correct any information that has changed or is otherwise inaccurate and must report any new registration information. A sex offender must appear in person for these purposes not less frequently than—
(d) Reporting of departure and termination concerning residence, employment, and school attendance.
(g) Compliance with jurisdictions' requirements for registering and keeping the registration current.
(1) A sex offender who does not comply with a requirement of SORNA in conformity with the time and manner specifications of paragraphs (a) through (f) of this section must comply with the requirement in conformity with any applicable time and manner specifications of a jurisdiction in which the offender is required to register.
Example 1 to paragraph (g)(1). A sex offender convicted in a state does not initially register before release from imprisonment, as required by 34 U.S.C. 20913(b)(1) and paragraph (a)(1) of this section, because the state has no procedure for pre-release registration of sex offenders. Instead, the state informs sex offenders that they must go to a local police station within seven days of release to register. The sex offender must comply with the state's requirements for initial registration, i.e., the offender must report to the police station to register within seven days of release.
Example 2 to paragraph (g)(1). A sex offender does not register when he is released from custody, or does not register upon entering a jurisdiction to reside as required by 34 U.S.C. 20913(c) and paragraph (c) of this section, because the jurisdiction, at the time, does not register sex offenders based on the offense for which he was convicted. The jurisdiction later sends the sex offender a notice advising that it has extended its registration requirements to include sex offenders like him and directing him to report to a specified agency within 90 days to register. The sex offender must report to the agency to register within the specified timeframe.
Example 3 to paragraph (g)(1). A sex offender registers as required when released from imprisonment or upon entering a jurisdiction to reside, but the jurisdiction has no procedure for sex offenders to appear periodically in person to update and verify the registration information as required by 34 U.S.C. 20918 and paragraph (b) of this section. The jurisdiction later sends the sex offender a notice advising that it has adopted a periodic verification requirement and directing the sex offender to appear at a designated time and place for an initial update meeting. The sex offender must appear and update the registration as directed.
Example 4 to paragraph (g)(1). A sex offender does not report his email address to the jurisdiction in which he resides when he initially registers, or within three business days of a change as required by paragraph (e) of this section, because email addresses are not among the information the jurisdiction accepts for inclusion in its registry. The jurisdiction later notifies the sex offender that it has extended the registration information it collects to include email addresses and directs him to send a reply within a specified time that provides his current email address. The sex offender must comply with this direction.
