agencies; immigration; data sharing

Purpose

Mandates that the state and any state agency must share data requested by the U.S. government relating to unauthorized noncitizens, undocumented immigrants and visa overstays.

Background

The U.S. Immigration and Naturalization Service must provide an individual's citizen verification or immigration status information to a federal, state or local government seeking to verify citizenship or immigration status for any authorized purpose (8 U.S.C. § 1373(c)).

Officials or agencies of the state and counties, cities, towns and other political subdivisions of the state may not be prohibited or restricted in any way from sending, receiving or maintaining information relating to the immigration status, lawful or unlawful, of an individual or exchanging that information with any other federal, state or local governmental entity to: 1) determine eligibility for a public benefit, service or license provided by a federal, state or local municipality; 2) verify a claim of residence or domicile if the determination is required under state law or a judicial order for a civil or criminal proceeding; 3) if the person is not a U.S. citizen, determine whether the person is in compliance with the registration requirements prescribed by the federal Immigration and Nationality Act; or 4) otherwise comply with federal law (A.R.S. § 11-1051).

            There is no anticipated fiscal impact to the state General Fund associated with this legislation.

Provisions

1. Requires the state and any state agency to share any data requested by the U.S. government regarding the status of or any information relating to an unauthorized alien, an undocumented immigrant or any individual who overstays the individual's visa in Arizona.

2. Specifies that the mandate is notwithstanding any other law.

3. Repeals the mandate on January 1, 2029.

4. Becomes effective on the general effective date.
