In the United States, the organizer of a public assembly must typically apply for and obtain a permit in advance from the local police department or other local governmental body.
[10] Applications for permits usually require, at a minimum, information about the specific date, time, and location of the proposed assembly, and may require a great deal more information.
[11] Localities can, within the boundaries established by Supreme Court decisions interpreting the First Amendment right to assemble peaceably, impose additional requirements for permit applications, such as information about the organizer of the assembly and specific details about how the assembly is to be conducted.
