Full Fair and Complete Exchange Act or the FACE Act This bill requires the federal government to compensate land owners the full fair market value for land seized for the construction of any barrier or related infrastructure at the U.S.-Mexico border. The government shall not take possession of such land before the compensation has been received and all relevant court proceedings have been completed. For tribal land, the government shall secure the approval of all relevant tribal stakeholders before taking possession. The bill also imposes various consultation and public meeting requirements related to such land acquisitions.
