This bill mandates that the Secretary of Homeland Security establish a rule within 180 days of its enactment to ensure the secure delivery of immigration status documents. The rule will require that any such document mailed via the United States Postal Service include a trackable accountability measure . These measures are designed to provide verifiable delivery and can take one of two forms. They can be a Postal Service barcode or similar marking that allows for the tracking of each individual document, or a requirement for a signature of the recipient for documents sent from United States Citizenship and Immigration Services facilities. This provision specifically excludes documents that are presented to an individual in person.
