Tapia, Martin: Home

Federal Preemption and Immigration Law

Introduction

Welcome everyone!

My name is Martin Tapia. I am a 3L student at Ave Maria School of Law.  This research guide is designed to provide with some introductory information on the relation between the preemption clause of the U.S. Constitution and Immigration law. Specifically, why most state laws regulating immigration matters are frequently struck down by federal courts. 

The U.S. Supreme Court ("Court") has ruled that “the authority to control immigration… is vested solely in the Federal government.” Traux v. Raich, 239 U.S. 33, 42 (1915).  As the exclusive power to regulate immigration is vested in the federal government, it is assumed that all states laws regulating immigration are displaced by federal law. In this regard, the primary federal immigration statute is the Immigration and Nationality Act (“INA”), which is codified in Title 8 of the United States Code.Thus, the Court has stricken down numerous state laws because they attempted to regulate immigration. Furthermore, the Court has held that “State[s] may not pursue policies that undermine federal law.” Arizona v. United States, 132 S. Ct. 2492, 2510 (2012).

However, the Court has also held that not all state laws regulating aliens are automatically invalid: “the Court has never held that every state enactment which in any way deals with aliens is a regulation of immigration and thus per se pre-empted by this constitutional power, whether latent or exercised.” De Canas v. Bica, 96 S. Ct. 933, 936 (1976). Thus, in case wherein a state or local government enacts a law which might be immigration-related, this law may not be unconstitutional as it would not be preempted by federal.

One of the most recent cases is the Arizona v. United States, 132 S.Ct. 2492 (2012), where the Court, after striking three sections based on preemption grounds, did not strike a fourth section of the Arizona statute authorizing state law enforcement officers to investigate a suspect's immigration status. Furthermore, the Court has also ruled that the Federal government power over immigration is not too broad as some states statutes indirectly regulating immigration have survived constitutional challenges. 

Therefore, as federal immigration law does not always preempt state laws touching immigration matters, this research guide will provide some material to determine when the preemption clause of the U.S. Constitution permits federal laws trump over state laws.

Statutes

The U.S. Constitution contains the Supremacy Clause, which mandates that federal law preempts state law. Also, the U.S. Constitution vests the Federal Congress with the power to regulate the naturalization process.

The Immigration and Nationality Act is the primary federal law regulating the immigration law in the United States.

Legislative History

No legislative history on the U.S. Constitution. However, the Immigration and Nationality Act (INA) of 1952 does have some legislative history..
