DHS is authorized to acquire new interests in lands under the INA. However, the federal
government may already own some land along the border pursuant to presidential proclamations
made long ago. In 1907, President Roosevelt reserved from entry and set apart as a public
reservation all public lands within 60-feet of the international boundary between the United States
and Mexico within the State of California and the Territories of Arizona and New Mexico.63
