Engineers Without Borders International (EWB-I) is an international association of some national EWB/ISF groups, whose mission is to facilitate collaboration, exchange of information, and assistance among its member groups that have applied to become part of the association. EWB-I helps the member groups develop their capacity to assist poor communities in their respective countries and around the world. The main office of EWB-I resides in the USA with regional offices in Mexico, India, Belgium, and Egypt. The regional offices serve as the first point of entry for those national EWB/ISF groups that wish to apply for membership of EWB-I and represent the EWB/ISF groups that are part of the association. EWB-I is run by an international board composed of representatives of many EWB/ISF groups.
