While the federal government makes the ultimate decision whether to admit or deport a noncitizen, the states often play a crucial role. Several provisions of federal immigration law that trigger deportation depend in large part on crimes that are defined, charged, and sentenced at the state level. Even a conviction for a low-level crime for which a state imposes no jail time can result in serious immigration consequences—including deportation.
Some states are adopting policies to take account of the immigration consequences of criminal convictions. This explainer will briefly review the intersection of state criminal law and federal immigration law. It will then outline several ways in which states are exercising their authority over state criminal law and procedure to influence federal immigration enforcement.
I. Background: Crimmigration
The intersection between immigration and criminal law is highly complex. Although immigration proceedings are civil matters, some criminal convictions may make a noncitizen deportable or inadmissible under federal law. This interplay between immigration law and criminal law is often referred to as “crimmigration.”
The Immigration and Nationality Act (INA), the federal law that governs immigration, includes a broad set of crimes for which a conviction may make a noncitizen—even a lawful, permanent resident—deportable or ineligible for certain immigration relief. This includes both federal and state crimes, many of which are not defined in the INA.
Several provisions of the INA set out only a category of crimes for which a conviction will trigger immigration consequences. For example, a noncitizen may be deported for having committed a “crime involving moral turpitude” or an “aggravated felony.” Whether specific crimes count as crimes involving moral turpitude, or aggravated felonies, depends on a state’s definition of the crime and the potential sentence permitted under state law. This means that the same criminal acts may trigger deportation if committed in one state, but not if committed in another state.
Recognizing the highly complex and technical laws involved, and the seriousness of deportation as a consequence of a criminal plea, the United States Supreme Court’s 2010 case Padilla v. Kentucky held that defense attorneys are constitutionally obligated to advise their clients about whether their plea carries a risk of deportation. The Padilla decision injected immigration law directly into the practice of criminal defense attorneys, prosecutors, and judges alike. Failure to advise a noncitizen client about the immigration consequences of their plea is ineffective assistance of counsel under the Sixth Amendment for which a defendant may seek post-conviction relief.
II. State efforts to limit immigration consequences of criminal convictions
Since the Supreme Court’s ruling in Padilla, many states have made changes to their criminal systems to take into account the immigration consequences of criminal convictions for noncitizen defendants.
Padilla counsel. In 2011, the state of New York authorized funding for immigration-related legal support, training, and resources to assist indigent-defense and family-law attorneys in complying with the mandate of Padilla. The result was the nation’s first statewide network of immigration assistance centers to advise criminal and family court attorneys on immigration law. The six Regional Immigration Assistance Centers (RIAC) issue advisory letters that analyze the potential immigration consequences of a case disposition and offer possible dispositions that reduce the immigration impact on the noncitizen.
Prosecutorial discretion. Some prosecutors have changed the way that they charge low-level and nonviolent offenders to take into account the potential immigration consequences of a conviction. In 2016, California enacted a statewide law mandating that prosecutors “consider the avoidance of adverse immigration consequences in the plea negotiation process” for all cases. Elsewhere, individual prosecutor’s offices have adopted similar practices. In Baltimore, the state’s attorney instructed the office’s prosecutors to consider the “unintended collateral consequences that our decisions have on our immigrant population.” In Brooklyn, NY, and Philadelphia, PA, the district attorneys’ offices have hired immigration counsel to train prosecutors on how to minimize the risk of deportation for noncitizens charged with low-level and nonviolent offenses.
Executive pardons. In some instances, states have the power to remove immigration consequences associated with past convictions. For most crimes, a state governor’s pardon has the effect of erasing a conviction for immigration purposes and protecting a noncitizen from deportation on account of the conviction. For some crimes—drug and firearm convictions, for example—a governor’s pardon may remove the automatic deportation trigger, giving the immigration judge the discretion to issue relief.
In 2000, the Georgia Board of Pardons and Parole made two key procedural changes to its pardon process in order to protect noncitizens at risk of deportation because of convictions for low-level state crimes. First, the Board opened its pardon process to misdemeanors, and second, it waived the otherwise applicable eligibility waiting period. In a 15-month period, the Board pardoned 138 legal permanent residents at risk of deportation—all of whom had either a U.S. citizen spouse or children and all but one of whom had been convicted of only a misdemeanor.
State governors in New York and California have recently exercised their discretion in this space, commuting the sentences of people convicted of crimes that carry the potential for immigration consequences. In California, a new law requires the state parole board to consider an expedited review of pardon applications from people at risk of deportation.
Reducing misdemeanor sentences. A noncitizen can be subject to deportation for a single conviction of a crime involving moral turpitude or an aggravated felony when the potential sentence for the crime is a year or more. The immigration law does not define a crime of moral turpitude, but courts have explained that it includes theft and fraud crimes—even misdemeanors like petit larceny or passing a bad check. Even when a person doesn’t spend a single day in jail, conviction for a crime involving moral turpitude with the potential for a one-year sentence makes deportation automatic. Similarly, a conviction for an aggravated felony, for immigration purposes, often includes misdemeanor crimes. Possession of stolen property, forgery, or failure to appear in court—often misdemeanors under state law—render a noncitizen deportable when a sentence of a year or more is imposed.
New York recently became the fifth state to amend its criminal laws to reduce the maximum penalty for misdemeanors from 365 days to 364 days in order to remove those crimes from the class of convictions that trigger deportation and inadmissibility.
Decriminalization. States have broad authority to define classes of unlawful behavior. Unlawful acts that are less than criminal—infractions or violations, for example—do not typically come along with the same constitutional guarantees (e.g., right to counsel) as for criminal activity. For this reason, sanctions for noncriminal offenses will not usually constitute convictions for immigration purposes.
Some states have moved to decriminalize certain unlawful behaviors so as not to subject noncitizens to detention and deportation based on these low-level violations. In 2018, California passed a law decriminalizing street vending after a widely-publicized incident in which a woman who had been arrested for selling corn in a public park was held in immigration custody for 6 months. Under the new law, local governments are permitted to set up regulatory structures to regulate street vending; vendors who violate local regulations are subject to administrative penalty only.
Notably, a state’s decision to decriminalize the possession, use, or sale of cannabis (marijuana) will not remove some immigration consequences associated with it. The U.S. Department of Justice recently issued a policy alertto indicate that a noncitizen may be found to lack the “good moral character” necessary to become a U.S. citizen because of their involvement with cannabis, “even where such activity is not a criminal offense under state law.” 
The federal government has exclusive authority to determine which noncitizens it will permit to enter and remain in the country. But immigration law relies heavily on the states to define crimes that trigger deportation of noncitizens. Because the states enjoy exclusive authority over state criminal laws, states have the ability to influence federal immigration enforcement. No state-law measure could take away the federal government’s power over the nation’s immigration laws and enforcement. But some states are exercising their authority at the intersection of criminal and immigration law to exert some measure of control over the effect that states’ actions have on the immigration status of people who encounter their criminal-justice systems.
