LESC, or the Law Enforcement Support Center, is responsible for providing responses to inquiries made by law enforcement agencies related to immigration and alien files. When an inquiry into the INS Alien File is made, LESC typically generates an automated acknowledgment to confirm receipt of the inquiry. This automated system is efficient and enables timely communication between law enforcement agencies and immigration services.

The automated acknowledgment serves multiple purposes: it verifies that the inquiry has been successfully received, ensures that the requesting agency knows that their request is being processed, and it allows for tracking the inquiry without the need for more cumbersome methods such as physical documents or verbal confirmations. This system enhances the efficiency of communication in law enforcement operations.
