A typical day for a Coast Guard Investigative Service agent involves conducting interviews, collecting and analyzing physical and digital evidence, and writing detailed investigative reports. Agents may be assigned to work on cases related to maritime law violations, drug trafficking, fraud, or internal affairs. Collaboration with other law enforcement agencies, both within and outside the Coast Guard, is common, requiring effective teamwork and communication. While office duties such as paperwork and case management are routine, agents should also expect to respond to field operations or incidents at a moment's notice, making flexibility and readiness key parts of the job.
