When it comes to immigration enforcement, the roles of a police officer, sheriff, and state trooper differ significantly, primarily based on their jurisdiction and authority.
Although all three are law enforcement officers, their responsibilities in immigration matters are limited and largely determined by their specific areas of operation. .
Their involvement in immigration matters typically occurs when federal agencies such as Immigration and Customs Enforcement (ICE) request assistance or when immigration violations are linked to criminal activity, but they are not authorized to actively pursue or arrest individuals based solely on their immigration status.
Local police officers
Local police officers are responsible for enforcing the laws within a specific city or town. Their responsibilities typically include responding to emergencies, investigating crimes, and ensuring public safety within their jurisdiction.
Police officers typically do not have direct authority to enforce federal immigration laws unless they have specific training or guidance.
However, in certain situations, they can detain people suspected of being in the country illegally. But they generally must transfer responsibility for immigration matters to federal immigration authorities, such as ICE.
Some of the limitations police officers face are due to “sanctuary policies” supported by local police departments, which restrict cooperation with federal immigration authorities, especially in non-criminal situations such as routine traffic stops or arrests.
County Sheriffs
Sheriffs are law enforcement officers who operate at the county level. They have jurisdiction over unincorporated areas—areas outside of a city or town—as well as managing county jails and are responsible for executing arrest warrants, eviction notices, and court orders.
Sheriffs may have some interaction with immigration issues, particularly in the management of county jails.
Following the passage of HB 10, North Carolina sheriffs must cooperate with ICE to assist in identifying subjects detained for certain crimes .
Highway patrols
Troopers, also known as highway patrol officers, are law enforcement officers employed by the state government who generally focus on enforcing laws on state roads, highways, and other state property.
They are responsible for monitoring traffic, investigating accidents, and enforcing laws related to the operation of vehicles.
State troopers, like local police and sheriffs, do not have general authority to enforce federal immigration laws.
