California Penal Code: Immigration Consequences of Crimes

If you are not a U.S. citizen, a California criminal case can do more than put you in jail or on probation. The immigration consequences of crimes in California can include deportation, a permanent bar on reentering the country, loss of a green card, and denial of citizenship, and those consequences can follow convictions that look minor on the state side. A misdemeanor plea with no jail time can still end your ability to remain in the United States. California law builds in protections and remedies for noncitizens, but they only help if you understand how a state charge translates into federal immigration law.

Which California Convictions Put a Noncitizen at Risk

Federal immigration law groups criminal convictions into several categories. A single California conviction can fall into more than one, and the categories do not line up neatly with how California labels its offenses.

Crimes Involving Moral Turpitude

Crimes involving moral turpitude are offenses federal courts have characterized as involving dishonesty, fraud, or conduct that shocks the conscience. There is no precise statutory definition. In California, theft under Penal Code 484, grand theft under Penal Code 487, forgery under Penal Code 470, and identity theft under Penal Code 530.5 consistently land in this category.¹²

A single such conviction makes a noncitizen deportable if the offense was committed within five years of admission to the United States and carries a possible sentence of one year or more. Two or more convictions make a person deportable regardless of when they occurred, as long as they did not arise from a single incident.³ The same conviction can also make a person inadmissible, which blocks visas, green cards, and reentry after travel. A narrow “petty offense exception” applies when a person has only one such conviction, the maximum possible sentence did not exceed one year, and the actual sentence was six months or less.⁴

Controlled Substance Offenses

Drug convictions are among the most damaging charges a noncitizen can face. Federal law makes virtually any controlled substance violation a ground for deportation, with one narrow exception: a single offense of possessing 30 grams or less of marijuana for personal use.³ Everything else, including possession under Health and Safety Code 11350 and sale or transportation under Health and Safety Code 11352, can place a noncitizen in removal proceedings.⁵ A Section 11352 conviction is particularly dangerous because it can qualify as a drug trafficking aggravated felony when the record identifies a federally listed substance.

Even possession of drug paraphernalia under Health and Safety Code 11364 can make a person inadmissible, despite carrying no significant criminal penalty. One nuance matters at the plea stage: if the record of conviction does not identify which controlled substance was involved, the conviction may avoid the federal deportation ground, because immigration authorities cannot prove the substance appears on the federal schedule.

Domestic Violence and Crimes Against Children

Federal law creates a separate deportation ground for domestic violence, stalking, and child abuse convictions. There is no five-year window and no sentence threshold here. Any qualifying conviction committed after admission makes a noncitizen deportable.⁶

In California, corporal injury to a spouse or cohabitant under Penal Code 273.5 almost certainly triggers deportability. Misdemeanor domestic battery under Penal Code 243(e)(1) can also lead to removal, because the federal statute focuses on the nature of the offense rather than the sentence.⁷ Felony child endangerment under Penal Code 273a(a), which involves circumstances likely to cause great bodily harm or death, is treated as a deportable crime of child abuse; the misdemeanor version under subdivision (b) is generally classified differently but still warrants careful analysis.⁸ A court finding that a noncitizen violated the protective portion of a stay-away order is itself a deportation ground, even without a new conviction.

Firearm Offenses

Any conviction related to purchasing, selling, possessing, or carrying a firearm or destructive device can make a noncitizen deportable.³ In California, that most often means possession by a prohibited person under Penal Code 29800 or carrying a concealed firearm without a permit under Penal Code 25400.⁹ The federal deportation ground requires the weapon to meet the federal definition of “firearm” under 18 U.S.C. § 921(a), and some California weapons offenses cover devices that fall outside that definition. The specific charge and its elements can determine whether the conviction triggers the firearms ground at all.

Aggravated Felonies

The aggravated felony label carries the harshest consequences in immigration law. A noncitizen convicted of an aggravated felony is deportable, barred from most forms of relief including asylum and cancellation of removal, subject to mandatory detention without bond, and permanently inadmissible.¹⁰ The name is misleading. Many offenses that qualify as aggravated felonies under federal immigration law are misdemeanors under California law.

California convictions that commonly qualify include robbery under Penal Code 211 (as a crime of violence when the sentence is one year or more), burglary under Penal Code 459 (as a theft or burglary offense when the sentence is one year or more), drug sale or transportation under Health and Safety Code 11352 when the record identifies a federally listed drug, fraud offenses where the victim’s loss exceeds $10,000, and any theft conviction with a sentence of one year or more.¹⁰

The sentence threshold is where many cases turn. For immigration purposes, “sentence” includes any period of incarceration ordered by a court, even if the sentence is suspended entirely.¹¹ A suspended one-year sentence with no actual jail time counts the same as a year served.

Deportability Versus Inadmissibility

Federal immigration law has two separate penalty tracks, and the same conviction can hit one, the other, both, or neither.

Deportability applies to noncitizens already present after lawful admission. The grounds based on criminal convictions appear in 8 U.S.C. § 1227 and include crimes involving moral turpitude, aggravated felonies, controlled substance violations, firearms offenses, and domestic violence convictions.³ A deportable noncitizen can be placed in removal proceedings before an immigration judge.

Inadmissibility applies when a noncitizen is trying to enter the country, obtain a visa, get a green card, or adjust status. The criminal inadmissibility grounds under 8 U.S.C. § 1182 are broader in some respects, and a single conviction for a crime involving moral turpitude or a controlled substance violation can block entry or adjustment.⁴ Green card holders who travel abroad face a specific trap. On return, they are treated as seeking admission, so a conviction that caused no trouble at home can suddenly make them inadmissible at the border. An old conviction that was never an issue can surface years later, leading to questioning, card confiscation, or removal proceedings on reentry.

Why the 364-Day Rule Matters

Several of the thresholds above turn on a one-year sentence. Penal Code 18.5 caps the maximum sentence for any California misdemeanor at 364 days instead of one year.¹² That single day of difference is one of the most meaningful immigration protections in state law. A moral turpitude offense is deportable only when a sentence of one year or longer “may be imposed.” Several aggravated felony categories require an imposed sentence of at least one year. The petty offense exception to inadmissibility also depends on whether the maximum possible sentence exceeded one year. Capping misdemeanors at 364 days pushes California misdemeanors below each of those triggers.

The cap applies retroactively, but with a catch. Someone sentenced to one year in county jail before January 1, 2015 can petition the sentencing court to modify the sentence to 364 days.¹² The Board of Immigration Appeals has held that it will not treat older convictions as capped unless the defendant actually obtains that modification from the trial court. If you have an older misdemeanor sentence of exactly one year, getting a formal reduction is a concrete step worth taking.

What Should Happen at the Plea

Before a California court accepts a guilty or no-contest plea, the judge must read a specific warning on the record: if you are not a U.S. citizen, a conviction may result in deportation, exclusion from the country, or denial of naturalization. Penal Code 1016.5 requires this advisal verbatim. If the court skips it and the conviction later carries immigration consequences, the court must vacate the conviction and let the defendant withdraw the plea. When no record of the advisal exists, the law presumes it was not given.¹³

The judge’s generic warning is a floor. Penal Code 1016.3 requires defense attorneys to go further by giving accurate, case-specific advice about the immigration consequences of any proposed plea, and, where possible, by negotiating a disposition that avoids or minimizes those consequences.¹⁴ This duty codifies the U.S. Supreme Court’s holding in Padilla v. Kentucky, which recognized that competent counsel on immigration consequences is part of the Sixth Amendment right to counsel. If your lawyer has not given you specific advice about how a proposed plea will affect your status, ask. If a plea is already on the table, ask whether a different charge or sentence structure would carry a different immigration result.

Fixing an Old Conviction

California offers several routes to address convictions already on your record. They vary dramatically in how much protection they actually provide under federal law.

Vacating a Conviction Under Penal Code 1473.7

Penal Code 1473.7 is the strongest tool California provides. It lets a person who is no longer in criminal custody move to vacate a conviction or sentence when a prejudicial error damaged their ability to understand, defend against, or knowingly accept the immigration consequences of the plea.¹⁵ To win, the moving party must prove two things by a preponderance of the evidence: that such a prejudicial error occurred, and that the conviction is currently causing or could cause removal, denial of an immigration benefit, or denial of naturalization. The motion does not require proving ineffective assistance of counsel, though that can be part of the argument. There is no strict time limit while the person remains out of custody.

When a conviction is vacated under 1473.7, the plea is withdrawn and the case returns to its pre-plea posture. The prosecution may refile or offer a new deal, which opens the door to an immigration-safe resolution that was missed the first time.

Why a Standard Expungement Will Not Save You

Many people assume a California expungement under Penal Code 1203.4 solves the immigration problem. It does not. The statute lets defendants who completed probation withdraw the plea and have the case dismissed, which matters for state purposes like employment applications.¹⁶ But 8 U.S.C. § 1101(a)(48)(A) defines “conviction” independently: a conviction exists for immigration purposes whenever a person enters a guilty or no-contest plea and the judge imposes any punishment, penalty, or restraint, even if the case is later dismissed or set aside under state law.¹¹ A 1203.4 expungement replaces the conviction after the fact; it does not erase the plea. Immigration courts will still treat the original plea as a conviction.

Drug Diversion Dismissals Under Penal Code 1203.43

For drug cases, Penal Code 1203.43 offers stronger relief than a standard expungement. A person who successfully completed a deferred entry of judgment drug program can withdraw the guilty plea entirely, and the court dismisses the case. The stated legislative purpose was to eliminate the immigration consequences attached to drug diversion pleas entered on or after January 1, 1997. Because this remedy targets the plea itself, it is more likely than a 1203.4 dismissal to be recognized in immigration proceedings.

Naturalization and Good Moral Character

Applicants for U.S. citizenship must show good moral character for at least five years before filing and continuing through the oath ceremony.¹⁷ A criminal record can block naturalization even when it does not make the applicant deportable.

A conviction for an aggravated felony at any time permanently bars a finding of good moral character. During the statutory period, the following also bar it: a conviction for a crime involving moral turpitude; any controlled substance violation other than simple possession of 30 grams or less of marijuana; two or more convictions with aggregate sentences of five years or more; confinement in jail or prison for 180 days or more; and false testimony under oath to obtain an immigration benefit, regardless of materiality.¹⁸¹⁹

USCIS is not confined to the five-year window. The agency can look at conduct from any point in the applicant’s past if it appears relevant or if behavior inside the statutory period does not show reform.¹⁹ A decades-old conviction that seemed safely buried can still support a denial.

The California Values Act and Contact With ICE

California limits how state and local law enforcement interact with federal immigration authorities. Government Code 7284.6, enacted as SB 54, prohibits California agencies from using personnel or resources to investigate, detain, or arrest people for immigration enforcement. Officers cannot ask about immigration status, hold someone solely on an ICE request, participate in arrests based on civil immigration warrants, or share personal information like home or work addresses with immigration authorities.²⁰

Government Code 7282.5 carves out exceptions tied to criminal history. Agencies may cooperate with ICE when the individual has been convicted of a serious or violent felony, any felony punishable by state prison, or specific categories of other offenses within defined look-back periods, including assault, battery (and domestic violence under Penal Code 273.5), burglary, robbery, fraud, weapons offenses, crimes against children, and felony DUI.²¹ Cooperation is permitted, not required, and practice varies by jurisdiction.

When a noncitizen is booked into a California jail, ICE may issue a detainer asking the jail to hold the person past their scheduled release. Under the Values Act, local jails generally cannot honor these requests. Transfer to ICE custody requires a judicial warrant, a judicial probable cause determination, or that the individual meet the criminal history criteria under Government Code 7282.5.²⁰ None of this stops ICE from acting on its own. Federal agents can arrest people at courthouses, homes, workplaces, and on release from custody. The Values Act reduces federal immigration enforcement inside California; it does not eliminate it. Noncitizens with convictions that fall within the exception categories face substantially higher exposure.

If you are facing a California criminal charge and you are not a citizen, the single most important step is making sure your defense attorney treats the immigration consequences as part of the case, not an afterthought. If a case is already closed, a careful review by an immigration-aware attorney can tell you whether the 364-day modification, a 1473.7 motion, or a 1203.43 dismissal is available to you, and what each one would and would not fix.
