The IASA (Instituto Alarma y Seguridad Aruba) is a key government entity under the Ministry of Justice that serves as Aruba’s primary border control authority. It manages the flow of people entering and exiting the island, working at the airport and sea ports to ensure national security. While DIMAS handles long-term residency and work permits, IASA is responsible for short-term stays, tourist admissions, and the daily enforcement of immigration laws at the border.
