Some states hold an exam to get the license. A licensed private investigator can investigate any kind of case. There are different types of cases which need private investigation. For example, cases of matrimony, like cheating, fraud, suspicion over the spouse, etc. need investigations which can be kept secret.
Other cases of crimes in the field of insurance, business, murder cases etc. also need an investigator in order to find out the truth. There are many training centers for the training of investigation. One can do a professional course in the field of investigation and can acquire a license.
In the field of private investigation, there are people from military, police, federal services, and spies etc., who after their retirement take up this profession.
