USCCB Committee on Migration and Refugee Services:
Creating a world where immigrants, refugees, migrants, and people on the move are treated with dignity, respect, welcome and belonging.
Grounded by our belief in Jesus Christ and Catholic teaching, Migration and Refugee Services (MRS) fulfills the commitment of the U.S. Catholic bishops to protect the life and dignity of the human person. We serve and advocate for refugees, asylees, migrants, unaccompanied children, and victims of human trafficking.
