Catherine is assigned to the Nashville Sub-office which is a sub-office of the New Orleans Field office. She has jurisdiction over three sub-offices assigned to the New Orleans Field Office. The three sub-offices include the Nashville, Chattanooga and Knoxville Enforcement and Removal Operations (ERO) offices. These three offices are Criminal Alien Program offices and the employees participate in the criminal alien program wherein they review numerous local, county, state and federal jails to identify criminal aliens who meet the current Immigration and Customs Enforcement priorities. The Nashville sub-office also has a Fugitive Operations Team. The team is responsible for targeting subjects who have a final order of removal. Due to limited resources, the majority of the subjects are high priorities including convicted criminals and subjects who present a threat to public safety and national security.
