Which of the following professionals is most likely to be involved in the registration process for Customs Brokers?

The Commissioner is integral to the registration process for Customs Brokers because this role involves overseeing the administration of customs laws and regulations within a country's customs authority. The Commissioner has the authority to establish the standards and procedures necessary for individuals to become accredited customs brokers.

In this context, the role of the Commissioner is vital as they ensure that the registration process is conducted according to the regulatory framework established by law. This ensures that customs brokers meet all necessary qualifications, adhere to compliance regulations, and maintain the integrity of customs operations.

While other professionals like legal counsel may provide guidance on legal matters and compliance, and customs inspectors focus on enforcement and regulation adherence, they do not directly handle the registration process itself. An account executive typically deals with sales or client relations and would not be involved in the accreditation of customs brokers. Thus, the Commissioner's direct involvement aligns with their regulatory responsibilities, making them the most likely professional to be engaged in the registration of customs brokers.
