Safe Zones Act of 2023 This bill makes changes to procedures relating to seeking asylum, including by establishing facilities outside of the United States to accept and process refugee applications to the United States. Specifically, the Department of State must establish safe zones that accept applications for asylum from individuals who are nationals of (1) the country where that safe zone is located, or (2) a country next to the country where the safe zone is located. The State Department must establish at least three safe zones along the U.S.-Mexico border and one safe zone in Guatemala. For each safe zone, the State Department must (1) ensure that it is fortified from danger; (2) provide temporary housing for individuals with pending applications; (3) provide adequate meals; and (4) provide access to various services, including medical services. The bill also imposes various requirements related to safe zones, including deadlines for processing applications. The bill expands the definition of asylum officer (i.e., officers who conduct initial credible fear reviews to determine whether an asylum seeker's application may proceed) to include trained and qualified staff as determined by the Department of Homeland Security (DHS). (In 2020, a federal court ruled that DHS may not use U.S. Customs and Border Protection agents to conduct such interviews.) The bill also requires the hiring of additional border patrol agents and immigration judges.
