The Pascua Yaqui Tribe has drafted regulations in an effort to formalize the border-crossing process for their relatives in Mexico coming to their reservation in Arizona. Like dozens of Native American nations across the U.S., the Pascua Yaqui Tribe was sliced in two by modern-day international borders. When deer dancers and musicians living in Sonora, Mexico, make the trip into the U.S. for ceremonies, they may be detained or have their cultural objects confiscated. The effort is part of their work with the U.S. Department of Homeland Security’s recently formed Tribal Homeland Security Advisory Council. DHS did not respond to repeated requests for comment on the status of the regulations.
