The main purpose of this legislation, known as the "Passport Sanity Act," is to prevent the U.S. Secretary of State from issuing passports, passport cards, or Consular Reports of Birth Abroad that include an unspecified gender designation, specifically the "X" option. This bill aims to standardize gender designations on these documents to only include "male" or "female." Key provisions of the bill require the Secretary of State to ensure that all applications for the specified documents only allow for the selection of "male" or "female" as gender designations.
