What does ADIS primarily deal with?

ADIS, which stands for the Arrival and Departure Information System, is primarily focused on capturing and managing data concerning the arrivals and departures of individuals in the United States. This system is crucial for tracking entry and exit information that helps in maintaining national security and managing immigration processes.

The correct choice highlights the primary function of ADIS, which centers around the logging of individuals' movements into and out of the country. This information is vital for various agencies involved in immigration enforcement and policy implementation, providing them with accurate data to make informed decisions regarding immigration status and maintaining the integrity of the U.S. borders.

While options regarding documentation of alien status, integration of immigration policies, and legal representation may relate to broader immigration processes, they do not specifically identify the core purpose of ADIS. This system does not focus on the documentation of status issues or legal matters; rather, its role is to track physical movements, supporting a more comprehensive view of immigration enforcement and management.
