The Minnesota Vietnam Association for BiNational Adoption proposes Minnesota establish an office here and in Vietnam to look for children in orphanages who need to be adopted. These children would then be sent to adoptive parents in Minnesota. A bill on this proposal is working its way through the Legislature. Lowell Gomrood says there could be 2000 half-American children who might be cared for and adopted under provisions of the bill. Five small agencies in Vietnam face obstacles in sending children to the U.S. for adoption and the conditions in orphanages are inadequate.
