The local organizations are referred to as Local Organization (LO) with a local board, and it is at the local level that most activities take place: conferences, projects, local publications, etc. A LO will be a member of a national organization or National Organization (NO) that is governed by a national board. The different NOs are members of Junior Chamber International.

The international organization publishes JCI World, a quarterly magazine, in six languages. It holds an annual conference, the JCI World Congress, in November of each year and regional annual meetings, the JCI Area Conferences. Leadership positions in the organization are held only for one year; this goes for JCI local Presidents, for JCI National Presidents, and also for the JCI World Presidents. Some members are given life membership of the organization and become "senators" and members of the JCI Senate. JCI Bangladesh is the national organization and is one of the active and result-driven youth national organizations of South Asia. Since 1998, the organization has been contributing to creating leaders and resulting in sustainable positive impacts in society. Currently, JCI Bangladesh has 40 Local Organizations (LO) with more than 5000 members all around the country under the strong leadership of Senator Mr. Ziaul Haque Bhuiyan, the 2023 National President of JCI Bangladesh. JCI Bangladesh encourages young people to become active citizens and to participate in efforts towards social and economic development, international cooperation, goodwill, and understanding.
