Which office is responsible for providing information about Customs Brokers with pending or resolved cases?

The appropriate office responsible for providing information about Customs Brokers with pending or resolved cases is the AMO, or the Appropriate Management Office. This office typically oversees regulatory compliance and handles cases related to customs brokers, ensuring that all activities meet the legal requirements set forth by customs regulations.

By having this designated office, the system ensures that there is a specific entity that can provide updates on the status of cases involving customs brokers, including any ongoing issues or resolutions that have been achieved. This role is essential for maintaining transparency and trust in the customs brokerage process, as it allows stakeholders, including customs brokers, to stay informed about their standing and any relevant actions taken.

The other options represent different entities or functions that may not be directly involved in case management for customs brokers. As such, AMO is the most relevant choice in the context of handling information regarding these cases.
