The Mexico-North Research Network, in collaboration with the US Department of State, Secretaría de Relaciones Exteriores, the Rockefeller Foundation, the Council of American Overseas Research Centers (CAORC), the Smithsonian Center for Latino Initiatives (SCLI), the US-Mexico Program at the National Museum of Natural History and the Cultural Institute of Mexico, hosted the IV Forum on U.S-Mexico Transnationalism and Transnational Communities on October 27th and 28th. The first day of the forum concentrated on the themes of Transnational Research and Education and Transnational Integration and Identity Construction and was followed by a reception, while the second day served as a showcase for recipients of the Mexico-North Research Network’s 2004 Transnationalism Fellowship Program. This is the first year that the forum has been held in Washington, DC and will undoubtedly strengthen US-Mexican relations.
