The Sulpicians are in charge of three seminaries in the United States, one in Zambia, and one in Malawi :

• Assumption Seminary in San Antonio, Texas

By concentrating upon the development of men for Hispanic ministry and for church leadership through collaboration in ministry, Assumption Seminary is meeting the challenge of calling forth effective leaders for the church as it moves into the next millennium.

• Emmaus Spirituality Centre of Lusaka, Zambia

Sulpicians priests serve in Zambia since the Zambian bishops call them to train young Zambian seminarians.
As a result, the Emmaus Spirituality Centre, a propaedeutic year of seminary formation, was established in 1989 in Zambia’s capital city, Lusaka. In the years that followed several Zambian priests, with the permission of their respective bishops, were invited to join the Sulpicians in their apostolate as Sulpicians of the U.S. Province serving in Zambia.

• St. Anthony's Seminary of Kachebere, Malawi

At the invitation of Cardinal Filoni, Prefect of the Congregation for the Evangelization of Peoples and Archbishop Murat, Nuncio of Zambia and Malawi, and with the approval of Very Rev. Ronald D. Witherup, PSS, Sulpician Superior General, the Province of the United States has taken responsibility for St. Anthony’s Seminary, Kachebere, Malawi. The Episcopal Conference of Malawi has entrusted the priestly formation of its seminarians to the Sulpicians beginning February 2018.
