MSBs are generally required to file a suspicious activity report (SAR) for a transaction that involves at least $2,000 and that the MSBs know, suspect, or have reason to suspect is relevant to a possible violation of law or regulation; this includes the cross-border transfer of funds derived from unlawful employment or otherwise derived from funds the MSB knows, suspects, or has reason to suspect were illicitly obtained in the United States by illegal aliens.
As such, to support the filing of SARs reporting a possible violation of law or regulation connected to cross-border transfers of funds by illegal aliens, financial institutions should use the SAR key term “FIN-2025-Alert003” in SAR field 2 (“Filing Institutions Note to FinCEN”) and the narrative.
