In order to work in criminal investigations for federal agencies such as the FBI, you'll need at least a bachelor's degree. A master's degree is often preferred in federal crime investigation. Suitable education subjects include criminal justice, biology, chemistry and psychology.
Military experience is usually highly valued by government agencies hiring federal criminal investigators. Joining a military organization in your area could help give you some of the experience needed to eventually become a federal criminal investigator. Even working as a security guard or in a collections agency can count toward your criminal investigations experience. Becoming a police officer in civilian or military policing could also be a good possible start to a criminal investigations career.
Your references and recommendations for past and current work experience should be excellent. You must have a clean criminal record as well as no outstanding debts. Physical fitness is mandatory for investigators. If you want to become a federal criminal investigator, you will most likely be tested on your physical fitness and energy level. Vision and hearing tests are also likely. Polygraph tests to indicate your honesty are given to aspiring investigators by most federal agencies.
A strong interest in investigating with the intent to solve crimes is necessary if you want to become a federal criminal investigator.

You should be able to work well on your own as well as within the larger scope of a team. You'll have to have a stable personality and be able to communicate with potentially violent people.
If you've completed the required education and experience as well as passed all agency tests, you will then take a federal criminal investigations training program. The training could take up to six months or even longer depending on the particular federal agency. You should expect the possibility of relocating if you hope to become a federal criminal investigator.
