What type of operation involves Immigration Checkpoints?

Immigration Checkpoints are a key component of Interior Enforcement Operations. These operations take place away from the immediate border area and focus on monitoring and controlling immigration status within a country's interior. By strategically placing checkpoints on highways and roads, Border Patrol agents can effectively conduct inspections of vehicles to verify the immigration status of individuals, thereby enhancing enforcement of immigration laws in areas that are not right at the border.

While roving patrols, border surveillance, and traffic control may involve aspects of immigration enforcement, they do not specifically pertain to the established, stationary nature of checkpoints where systematic inspections are conducted. Roving patrols are more mobile and discretionary, targeting suspicious activity; border surveillance focuses on monitoring border areas; and traffic control primarily pertains to road safety and regulations, not specifically immigration enforcement. Therefore, selecting Interior Enforcement Operations accurately reflects the intended focus and purpose of immigration checkpoints.
