The fact is the solution MUST be a federal one and this has long been resolved by the mandate of the Constitution and the precedence of Supreme Court Cases. In INS v. Chada, 462 U.S. 941 (1983) the court said that the plenary authority of Congress over aliens under Art. I, § 8, cl. 4, is not open to question
The Chada Court cites Buckley v. Valeo, 424 U.S. 1 (1976) which states: Congress has plenary authority in all cases in which it has substantive legislative jurisdiction, McCulloch v. Maryland, 4 Wheat. 316 (1819), so long as the exercise of that authority does not offend some other constitutional restriction."
The McCulloch Court also solidified that the Constitution is the Supreme Law of the Land. The Constitution NOT the State Law of Arizona on this issue that affects ALL the borders of the United States and not just Arizonas.
