An FBI agent is a member of our federal law enforcement branch. Their mission is to enforce our country’s laws, defend against terrorist threats, and provide assistance to all forms of law enforcement. This branch is responsible for investigating many types of criminal activity, as well as assisting other law enforcement agencies with their investigations. Their primary responsibility is to investigate interstate crime. Some of the types of crimes they investigate are cyber crimes, drug trafficking, international espionage, and highly sensitive security investigations. FBI agents will perform several activities in their pursuit of the criminals. These agents will conduct surveillance, monitor wire taps, and go undercover. They will also interview all types of people related to the crime. An FBI agent can work in the office on occasion and out in the field. This position usually requires a great deal of travel. With all of these duties, a 40-hour workweek can run into overtime.
