A national civil rights group is asking Knox County to withdraw its 287(g) application.
Back in August, immigrant rights advocates protested against the law. It allows authorities to check the legal status of anyone they suspect is in the country illegally.
Rutherford and Knox counties have submitted 287(g) applications.
Knox County Sheriff J.J. Jones has said the plan would allow jailers in the county to check a suspect's immigration status, but only if they were arrested and booked for the crime.
Right now, Davidson County is the only Tennessee county using the program.
Wednesday, the American Civil Liberties Group released a report on the impact of the program. According to the report, a majority of the deportations in Davidson County were triggered by minor, often traffic-related offenses.
The ACLU says the program encouraged racial profiling and forced immigrants to live in fear.
