Answer:
The Arizona v. United States decision struck down all Arizona's most restrictive provisions on illegal immigration.
Explanation:
Federalism is a form of government that stands in direct opposition to the notion of centralism, that is, to the form of political organization of states in which power appears centralized in the hands of a single governing group. Federalism, for its part, allows power (and the freedom to make decisions) to be distributed independently to the federal, state, and local government.
Under federalism, the rules governing immigration matters are different for the federal government, the state government, and the place where one can set their own guidelines for this. With regard to immigration, we can say that since the 1990s, states have increasingly adopted the political domain of immigration, and state involvement in immigration is partly due to their interest in preventing illegal immigrants from accessing public services, as educational and welfare benefits. In addition, we can state that federal immigration laws outperform state laws.
False information about immigration federalism is: "Arizona's decision against the United States overturned all of Arizona's most restrictive provisions on illegal immigration."
