How does the tier classification of my US sex offence affect international enforcement?

SORNA establishes three tiers based on offence severity and recidivism risk, with Tier III (most serious) requiring lifetime registration. Foreign authorities receiving Interpol Green Notices or bilateral intelligence generally see the tier classification and underlying offence description. Higher-tier classifications attract greater scrutiny — Tier III listings are far more likely to result in visa refusals, border detention, or local registration requirements abroad. Challenging tier classification domestically requires demonstrating misclassification under federal guidelines or pursuing state-level reclassification procedures where permitted, which typically involves risk assessment evidence.
