About Us

The Omaha Sister Cities Association (OSCA) is an all-volunteer 501(c)3 organization dedicated to promoting citizen diplomacy.  We operate on membership dues, corporate and personal contributions, and event income.  We are not funded by the City of Omaha.  Most of our expenses are from hosting visiting delegations from our sister cities, publishing our newsletter, and other special projects and events.


We have been a successful and growing organization for 44 years.  Our sister city affiliations are approved by the Omaha City Council and the Mayor.  These government officials are an important participant in our sisiter city delegation visits and in hosting our visitors in Omaha.  We attribute our success to our city government leadership and the broad base of student and adult volunteers.
