Relating to immigration documentation or other information to verify citizenship or immigration status and to notification to the federal government of an arrested or detained person who is unlawfully present in the United States; creating a criminal offense.

HB 3856 requires non-citizens in Texas who are legally required to carry federal immigration documentation to present it to police during a lawful detention. It makes it a misdemeanor (Class C, or Class B for repeat offenses or false information) to refuse to provide truthful immigration status, fail to show required documents, or give false information. The bill also mandates that police notify federal immigration authorities within 12 hours if they determine a detained person is unlawfully present in the U.S. This law directly affects non-citizens subject to federal immigration documentation requirements and law enforcement officers.
