A California criminal conviction can carry immigration consequences far heavier than the state sentence itself. Deportation, denial of a green card, a permanent bar on reentry, or a rejected citizenship application can follow from a misdemeanor plea that carries no jail time under state law. The immigration consequences of California crimes are governed by federal law, but California has built protections into its criminal process, capped misdemeanor sentences at 364 days, and created targeted post-conviction remedies that can undo damage a plea has already done.
Which California Convictions Put Immigration Status at Risk
Federal immigration law groups criminal grounds for removal into several categories. A conviction under California law triggers immigration consequences based on how the offense fits into these federal categories, not based on how serious the charge looks in state court.
Crimes Involving Moral Turpitude
Crimes involving moral turpitude are offenses federal courts have characterized as involving dishonesty, fraud, or conduct that shocks the conscience. The term has no precise statutory definition, and it remains one of the most litigated categories in immigration law. Theft, fraud, forgery, and certain violent offenses consistently fall into it.
A single moral turpitude conviction triggers deportability if the offense was committed within five years of the person’s admission to the United States and carries a potential sentence of one year or more. Two or more moral turpitude convictions make a person deportable regardless of when they occurred, as long as they did not arise from a single incident.1Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
Common California offenses in this category include petty theft under Penal Code 484 and grand theft under Penal Code 487, forgery under Penal Code 470,2California Legislative Information. California Penal Code 470 – Forgery and identity theft under Penal Code 530.5.3California Legislative Information. California Penal Code 530.5 – Identity Theft
Federal law provides a narrow “petty offense exception” to inadmissibility for a single moral turpitude offense where the maximum possible sentence did not exceed one year and the person was not actually sentenced to more than six months.4Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens For many California misdemeanors, this exception can be the difference between keeping and losing legal status.
Controlled Substance Offenses
Federal immigration law makes virtually any controlled substance violation a ground for deportation. The only exception is a single offense of possessing 30 grams or less of marijuana for personal use.1Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens Possession, sale, and manufacturing offenses all trigger removal proceedings.
In California, the charges that most often cause problems are possession of a controlled substance under Health and Safety Code 113505California Legislative Information. California Health and Safety Code 11350 – Possession of Controlled Substances and sale or transportation under Health and Safety Code 11352. A Section 11352 conviction is especially dangerous because it can qualify as a drug trafficking aggravated felony when the record identifies a federally listed substance, which carries mandatory deportation with almost no available relief.
Even offenses that seem trivial in state court can end a person’s ability to remain in the country. Possession of drug paraphernalia under Health and Safety Code 11364 can make a noncitizen inadmissible despite carrying no significant criminal penalty. And the specific substance identified in the record of conviction matters enormously. If a plea to a California drug charge does not identify which controlled substance was involved, the conviction may avoid the federal deportation ground because immigration authorities cannot prove the substance is federally listed.
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. Any qualifying conviction for an offense committed after admission makes a noncitizen deportable.6Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
California offenses that commonly trigger this ground include corporal injury to a spouse or cohabitant under Penal Code 273.5, misdemeanor domestic battery under Penal Code 243(e)(1),7California Legislative Information. California Penal Code 243 – Battery and felony child endangerment under Penal Code 273a(a), which involves circumstances likely to cause great bodily harm or death. The misdemeanor version of child endangerment under subdivision (b) is treated differently and generally is not classified the same way, though it still warrants careful analysis.8California Legislative Information. California Penal Code 273a – Child Endangerment
A court finding that a noncitizen violated the protective portions of a stay-away or restraining order also creates deportation exposure, without any new criminal conviction.
Firearm Offenses
Any conviction involving the purchase, sale, possession, or carrying of a firearm or destructive device as defined under federal law makes a noncitizen deportable. In California, the charges that most often raise this risk are possession of a firearm by a prohibited person under Penal Code 298009California Legislative Information. California Penal Code 29800 – Prohibitions on Firearm Access and carrying a concealed firearm without a permit under Penal Code 25400.
The federal deportation ground requires the weapon to meet the federal definition of “firearm” under 18 U.S.C. § 921(a). Many California weapons offenses cover devices that fall outside that federal definition, which can matter significantly during plea negotiations.
Aggravated Felonies
The aggravated felony label carries the harshest immigration consequences in federal law. A noncitizen convicted of an aggravated felony is deportable, permanently barred from most forms of relief including asylum and cancellation of removal, subject to mandatory detention without bond, and permanently inadmissible.10Legal Information Institute. 8 USC 1101(a)(43) – Aggravated Felony Definition The name is misleading. Many offenses classified as aggravated felonies under immigration law are misdemeanors under state law.
California convictions that frequently qualify include robbery under Penal Code 211 and burglary under Penal Code 459 when the sentence imposed is one year or more; drug trafficking under Health and Safety Code 11352 when the record identifies a federally listed drug; theft offenses including receipt of stolen property when the sentence imposed is one year or more; and fraud offenses where the victim’s loss exceeds $10,000.
The sentence threshold matters. Under federal immigration law, “sentence” includes any period of incarceration ordered by the court, even if the sentence is suspended entirely.11Office of the Law Revision Counsel. 8 USC 1101 – Definitions A suspended one-year sentence is treated the same as a year actually served.
Deportability and Inadmissibility Are Not the Same
Federal immigration law uses two separate penalty tracks for criminal convictions. A conviction can trigger one, both, or neither.
Deportability applies to noncitizens already inside the United States after having been admitted. The grounds are listed in 8 U.S.C. § 1227 and include moral turpitude crimes, aggravated felonies, controlled substance violations, firearms offenses, and domestic violence convictions. 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 in 8 U.S.C. § 1182 are broader in some respects. A single moral turpitude conviction or controlled substance violation can block entry or adjustment.
Green card holders face a particular trap. When they travel abroad and return, they are treated as seeking admission. A conviction that never caused problems while they stayed in the country can suddenly make them inadmissible at the border, resulting in questioning, confiscation of the card, or placement in removal proceedings based on a years-old case.
The 364-Day Rule and Why It Matters
California Penal Code 18.5 caps the maximum sentence for any misdemeanor at 364 days rather than one year.12California Legislative Information. California Penal Code 18.5 That single day is not a technicality.
Federal immigration triggers repeatedly use one year as the line. A moral turpitude offense committed within five years of admission is deportable only if 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 hinges on whether the maximum possible sentence exceeded one year. By capping misdemeanors at 364 days, California pushed its misdemeanor offenses below these federal thresholds.
The cap applies retroactively, but with a catch. A person sentenced to one year in county jail before January 1, 2015, may petition the sentencing court to modify the sentence to 364 days. The Board of Immigration Appeals has held that it will not apply the 364-day cap retroactively to pre-2015 convictions unless the defendant actually obtains that sentence modification. For noncitizens with older misdemeanor convictions, getting the modification is a concrete step worth pursuing.
Naturalization and Good Moral Character
Naturalization applicants must show good moral character for at least five years before filing and continuing through the oath ceremony.13U.S. Citizenship and Immigration Services. USCIS Policy Manual – Good Moral Character A criminal record can derail this even when the underlying conviction is not deportable.
A conviction for an aggravated felony at any time permanently disqualifies an applicant. During the statutory period, the following also bar a good moral character finding:
- A conviction for a crime involving moral turpitude
- Any controlled substance violation, except simple possession of 30 grams or less of marijuana14U.S. Citizenship and Immigration Services. USCIS Policy Manual – Conditional Bars for Acts in Statutory Period
- Two or more convictions with aggregate sentences totaling five years or more
- Confinement in jail or prison for 180 days or more
- False testimony under oath to obtain an immigration benefit, whether or not the lie was material15eCFR. 8 CFR 316.10 – Good Moral Character
USCIS is not limited to the five-year window. The agency can consider conduct from any point in the applicant’s past if it appears relevant or if the applicant’s behavior during the statutory period does not show reform. A decades-old conviction can still support a naturalization denial.
Plea-Stage Protections in California Courts
California has built safeguards into the plea process that go further than federal constitutional requirements.
Before accepting a guilty or no-contest plea, a California 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. This requirement comes from Penal Code 1016.5, and the warning must be read verbatim. If the court skips this step and the defendant later shows the conviction carries immigration consequences, the court must vacate the conviction and allow the defendant to withdraw the plea. When no record exists that the advisal was given, the law presumes it was not.16California Legislative Information. California Penal Code 1016.5 – Plea
The court’s warning is a floor, not a ceiling. Penal Code 1016.3 requires defense attorneys to provide accurate, case-specific advice about the immigration consequences of any proposed plea and, when consistent with the client’s goals, to try to negotiate a disposition that avoids or minimizes those consequences.17California Legislative Information. California Penal Code 1016.3 – Plea This codifies the Supreme Court’s holding in Padilla v. Kentucky that the Sixth Amendment requires competent counsel on immigration consequences.
If your defense attorney did not analyze the immigration consequences of your plea, or if the judge never gave you the required advisal, both are grounds you can raise later.
Fixing an Old Conviction
California offers several avenues to address convictions already on the record, but they vary sharply in the protection they provide under federal law.
Motion to Vacate Under Penal Code 1473.7
Penal Code 1473.7 lets a person no longer in criminal custody move to vacate a conviction or sentence that is legally invalid because of an error that damaged the person’s ability to understand or defend against immigration consequences.18California Legislative Information. California Penal Code 1473.7 – Motion to Vacate Conviction or Sentence This is the strongest tool California provides for challenging an old conviction on immigration grounds.
The moving party must prove two things by a preponderance of the evidence: that a prejudicial error damaged the ability to meaningfully understand, defend against, or knowingly accept the immigration consequences of the plea; 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 filing deadline, as long as the person is no longer in criminal custody.
When a conviction is vacated under this statute, the underlying plea is withdrawn and the case returns to its pre-plea posture. The prosecution can refile or offer a new plea deal, which creates the opportunity for an immigration-safe resolution.
Why a Standard Expungement Is Not Enough
Many people assume a California expungement solves their immigration problem. It does not. Penal Code 1203.4 lets defendants who completed probation withdraw the guilty plea and have the case dismissed.19California Legislative Information. California Penal Code 1203.4 The relief matters for state-law purposes like employment applications, but federal immigration law defines “conviction” on its own terms. Under 8 U.S.C. § 1101(a)(48)(A), a conviction exists for immigration purposes whenever a person enters a guilty or no-contest plea and the judge imposes any form of punishment, penalty, or restraint, even if the conviction is later dismissed or set aside under state law.
A 1203.4 expungement does not eliminate the guilty plea. Immigration courts still treat the original plea as a conviction. This is one of the most common and costly misunderstandings noncitizens face.
Drug Diversion Dismissals Under Penal Code 1203.43
For drug cases, Penal Code 1203.43 offers stronger relief than a standard expungement. It allows a person who successfully completed a deferred entry of judgment drug program to withdraw the guilty plea entirely, and the court dismisses the case. The legislative intent was explicitly to eliminate the immigration consequences that attached to drug diversion pleas entered on or after January 1, 1997. Because this remedy targets the plea itself rather than the conviction record, it is more likely to be recognized in immigration proceedings.
State Limits on Immigration Enforcement
California limits how state and local law enforcement interact with federal immigration authorities through the California Values Act, codified in Government Code 7284.6. State and local agencies cannot use 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 provide personal information like home or work addresses to immigration authorities.20California Legislative Information. California Government Code 7284.6
These restrictions are not absolute. Government Code 7282.5 lets law enforcement cooperate with ICE when an individual has been convicted of a serious or violent felony, any felony punishable by state prison time, or specific categories of misdemeanors and felonies within defined look-back periods, including assault, battery (including domestic violence under Penal Code 273.5), burglary, robbery, fraud, weapons offenses, crimes against children, and felony DUI.21California Legislative Information. California Government Code 7282.5
Transferring a noncitizen from a California jail to ICE custody requires either a judicial warrant, a judicial probable cause determination, or that the individual fits within these criminal history criteria. None of this stops ICE from conducting its own operations at courthouses, homes, workplaces, or upon release from custody. Noncitizens with convictions falling within the exception categories face substantially higher risk of encounters with ICE than those without qualifying records.
