The licensing in one state does not necessarily allow you to operate in another state. California has reciprocity with about half a dozen states and then they are probably another dozen states that allow you to operate in their state if the investigation initiated in your state and you crossed the state line as far as following the investigation. Some, however require you to register with them as an out of state investigator within 30 days, while some require you to register with them within 10 days. You can usually find those specific requirements are by checking on the Internet with whatever specific state you want to work in.
