The USA Province of the MSC supports activities and missions in Colombia (South America) and in countries in the South Pacific, South Asia and Africa.

The worldwide congregation of the Missionaries of the Sacred Heart is organized into Provinces, Regions, Unions and Sections, depending on how well-established the mission is. For instance, the Colombia Section started out as a mission of the MSC USA Province. Over the years, the mission has grown and fewer MSC from the USA were needed to carry out the projects there because several young Colombian men joined our congregation. The community in Colombia continues to grow, however the mission is still largely dependent on the MSC USA Province for financial support, and so the MSC Colombian Section is a part of the MSC USA Province.

Instead of being part of a province, the MSC Unions (MSC Africa Union, MSC India Union and MSC Pacific Union) are directly under the Generalate in Rome. Each Union relies on the support of the well-established MSC provinces around the world to help fund their projects and to train the new members of their rapidly growing communities. The United States Province of the Missionaries of the Sacred Heart sends financial support to each of these unions to help them complete their many mission projects and ministries.
