The surge of Obosi people (Ndi-Obosi) to U.S.A. and Canada started after the end of Nigeria Civil War (in 1970) to the late seventies. They settled across U.S.A. in different academic institutions and major metropolitan areas. From the early 1980s, a shift started to emerge. Due to the need to move closer to those they grew up with, stay closer to family members, or to be at a warmer part of the country, some Obosi families moved to Houston-Dallas corridor and Arkansas area. Houston accounted for the greatest number of Ndi-Obosi in U.S.A. from the late seventies to late eighties. Also, the northeastern U.S.A. (New York, New Jersey, Washington, and surrounding states) and Georgia maintained a sizable number of Obosi families. Houston was the first city in USA to have an organized Obosi meeting in the early 1980's.
Atlanta area inaugurated their union in the mid-eighties and subsequently Dallas, Texas; New York/New Jersey, Washington DC/ Maryland, Los Angeles, California; Chicago, Illinois; Bay Area/San Francisco, California formed local Obosi Associations. These town unions of Ndi-Obosi generated an awareness of where we reside and most importantly, how we are faring in this great land, U.S.A.
The seed for action was sewn and nurtured through one of the early efforts for a central organization directed toward embarking on projects at Obosi. This rallying cause brought out a need for a central organization and convention where Obosi people in USA could come and discuss topics of common interest. Thus, the inaugural convention of Obosi Development Association of USA (ODAUSA) was held on 4th of July weekend, 1995 in Atlanta, Georgia. The first convention was well represented by Obosi Sons and Daughters Association of Washington, Obosi Foundation of Dallas, Obosi Progressive Association of Houston, Obosi Indigenes of NY/NJ/CT, Obosi Association of Los Angeles, and Ndi-Obosi living in areas without town unions. It is worth mentioning that Obosi and Obosi Development Association was probably the first Nigerian town organization to hold a national convention in U.S.A.
After the convention, all autonomous Obosi unions across the country committed themselves to a strong central organization. Obosi families living far and outside an existing town union joined ODA. Ndi-Obosi in Chicago and San Francisco formed their town unions. The number of regional, autonomous Obosi unions under the umbrella of Obosi Development Association is eight (Atlanta, Georgia; Chicago, Illinois; Dallas, Texas; Houston, Texas; Los Angeles, California; New York/New Jersey/Connecticut; San Francisco, California; Washington/Baltimore/Maryland). A new branch, Obosi Sons and Daughters of New England came into existence in 2010. Canada is ODA’s new frontier. There is a strong interest of Ndi-Obosi in Canada to join ODA, with some families already playing important roles in the organization.
