What can be ordered under INA § 235(d)(2) concerning vessels?

Under INA § 235(d)(2), the correct action pertains to the authority to detain and deliver aliens for inspection. This section is part of the immigration and nationality laws that grant enforcement officials the power to manage individuals who arrive at the U.S. borders or ports of entry, particularly those seeking admission or engaging in transit.

The provision is significant because it allows designated immigration authorities—such as Customs and Border Protection (CBP)—to apprehend individuals suspected of violating immigration laws and to ensure they are properly processed and examined. This step is crucial for maintaining the integrity of U.S. immigration practices, as it facilitates thorough assessments of individuals' eligibility to enter or remain in the country.

The other options provided, such as releasing detained aliens, conducting health checks, and inspecting cargo, do not align directly with the specific powers granted under INA § 235(d)(2). While some of those activities might be part of broader immigration or customs enforcement procedures, the definite and designated process involved in the section emphasizes the action of detaining and delivering for inspection as essential to handling immigration cases at the borders.
