A criminal charge in California can trigger deportation proceedings, block a green card or visa renewal, and end your eligibility for U.S. citizenship — even for offenses that seem minor under state law. The consequences depend on the type of charge, your current immigration status, and how the case is resolved in court.
Federal immigration law — not California law — determines which criminal convictions lead to removal, inadmissibility, or denial of naturalization. That means a plea deal that looks favorable in an Orange County criminal courtroom can still carry mandatory immigration penalties. If you are not a U.S. citizen and you are facing criminal charges, the decisions made before a plea or conviction can determine whether you remain in the United States.

This article provides general information about the intersection of criminal and immigration law in California. It is not legal advice — each situation requires individual evaluation.
Why Do Criminal Charges Carry Immigration Consequences?
The Immigration and Nationality Act (INA) is the federal statute that governs who can enter, remain in, and be removed from the United States. Under the INA, certain criminal convictions automatically trigger deportation, make a person inadmissible (unable to obtain or renew a visa or green card), or disqualify someone from U.S. citizenship — regardless of how California state courts classify the offense.
This means that a misdemeanor under California law can be treated as an aggravated felony under federal immigration law. A plea to a reduced charge that avoids jail time can still count as a “conviction” for immigration purposes. And an arrest that never leads to charges can still affect a pending visa application, DACA renewal, or asylum claim.
The U.S. Supreme Court recognized the severity of this problem in Padilla v. Kentucky (2010). In that case, the Court held that deportation is so closely tied to the criminal process that it is effectively part of the penalty — not a side effect. The Court ruled that criminal defense attorneys have a Sixth Amendment duty to advise noncitizen clients about the immigration consequences of a guilty plea before the client decides whether to accept it. Failing to provide that advice constitutes ineffective assistance of counsel.
California took this further. Penal Code § 1016.2 codified the Padilla principle into state law, declaring that immigration consequences are an integral part of the criminal case for noncitizen defendants. Penal Code § 1016.3 requires prosecutors — not just defense attorneys — to consider the avoidance of adverse immigration consequences as a factor when negotiating plea agreements. And Penal Code § 1016.5 requires California courts to warn defendants before accepting a guilty or no-contest plea that the conviction may result in deportation, exclusion from the United States, or denial of naturalization.
These protections exist because the stakes are that high. But they only work when the defense attorney understands immigration law well enough to use them. Legal professionals use the term “crimmigration” to describe this intersection of criminal defense and immigration law — an area that requires fluency in both systems to navigate effectively.
Which Criminal Offenses Can Lead to Deportation in California?
Not every criminal charge triggers immigration consequences, but the categories that do are broader than most people expect. Federal immigration law groups offenses into specific classifications, each with different consequences.
Crimes Involving Moral Turpitude (CIMTs)
A crime involving moral turpitude (CIMT) is an offense that involves fraud, dishonesty, or conduct considered inherently wrong — theft, certain assaults, sex offenses, and fraud-based crimes typically fall into this category. There is no single statutory definition, so the classification depends on the specific elements of the charge.
A single CIMT committed within five years of admission to the United States, where the potential sentence is one year or more, can make a person deportable. Two or more CIMTs committed at any time — even years apart — can also trigger removal proceedings, regardless of when the person entered the country. Examples under California law include shoplifting under Penal Code § 459.5 (if classified as a theft offense involving intent to defraud), felony welfare fraud, and assault with intent to commit great bodily injury.
Aggravated Felonies
“Aggravated felony” is a federal immigration term defined by the INA — it does not correspond directly to California’s felony classifications. The category includes drug trafficking, firearms offenses, crimes of violence, sexual abuse, murder, fraud offenses involving losses over $10,000, and certain theft or burglary convictions where the sentence imposed is one year or more.
A conviction classified as an aggravated felony under the INA results in mandatory deportation with almost no available relief. The person becomes permanently barred from reentering the United States and is ineligible for most forms of immigration relief, including asylum. Even offenses that California treats as misdemeanors or “wobblers” can qualify as aggravated felonies if they meet the federal statutory criteria.
This is one reason California limits the maximum sentence for misdemeanors to 364 days rather than one year. A one-year sentence can trigger aggravated felony status under the INA, so that single day makes a significant difference in immigration consequences.
Drug Offenses
Drug convictions receive some of the harshest treatment under federal immigration law. Almost any controlled substance conviction — including simple possession under California Health & Safety Code § 11350 or § 11377 — can make a person deportable or inadmissible.
There is a narrow exception under federal law for a first offense involving simple possession of 30 grams or less of marijuana. But this exception is unreliable and does not apply in all immigration contexts. California’s legalization of recreational marijuana does not protect noncitizens, because marijuana remains a Schedule I controlled substance under federal law. Even admitting to drug use during an immigration interview — without any criminal conviction — can trigger inadmissibility findings.
If you were charged with a DUI involving drugs rather than alcohol alone, the immigration consequences are more severe. A drug-related DUI can be treated as a controlled substance violation for immigration purposes, separate from any analysis of whether DUI itself qualifies as a crime of moral turpitude. For more on how DUI charges interact with immigration status, see our article on what happens after a DUI arrest in California.
Domestic Violence and Firearm Offenses
Domestic violence convictions, stalking, child abuse, and violations of protective orders are independently deportable offenses under the INA — they do not need to qualify as crimes of moral turpitude or aggravated felonies to trigger removal. Certain firearm offenses, including unlawful possession, also carry deportation consequences regardless of how California classifies the offense.
How Does Your Immigration Status Affect What Happens?
The same criminal conviction can produce very different immigration outcomes depending on whether someone is undocumented, holds a temporary visa, or is a lawful permanent resident.
Undocumented Individuals
If you are undocumented, any contact with the criminal justice system increases the risk of immigration enforcement. An arrest — even without a conviction — can bring you to the attention of Immigration and Customs Enforcement (ICE). A criminal conviction accelerates removal proceedings and eliminates most forms of discretionary relief.
Under current federal enforcement priorities, noncitizens with any criminal history face heightened scrutiny. The practical reality is that an undocumented person who is arrested in Orange County may face removal proceedings regardless of whether the criminal case results in a conviction.
Visa Holders (H-1B, F-1, B-2, and Others)
If you hold a temporary visa — a work visa, student visa, tourist visa, or any nonimmigrant classification — a criminal conviction can lead to visa revocation, denial of renewal, or denial of adjustment of status if you are applying for a green card. Certain convictions also make you inadmissible, meaning you may be denied reentry to the United States if you leave the country.
Students and workers should consult an attorney before entering any plea. A conviction that seems manageable in criminal court can end your ability to remain in the country or return after travel.
Green Card Holders (Lawful Permanent Residents)
Lawful permanent residents are not immune from deportation. Certain convictions — aggravated felonies, CIMTs, drug offenses, domestic violence, and firearms offenses — can strip permanent resident status and trigger removal proceedings. If you are applying for U.S. citizenship, any criminal history is reviewed during the naturalization process, and even minor convictions can result in denial based on the “good moral character” requirement.
A criminal conviction from years ago can surface during a citizenship interview. A 2017 theft conviction in Orange County, for example, could become the basis for denying a 2026 naturalization application — or worse, placing the applicant in removal proceedings.
DACA Recipients
If you hold DACA status, a criminal conviction or even a significant misdemeanor can result in termination of your DACA protections. Because DACA is a discretionary program, any criminal history gives USCIS grounds to deny renewal. Losing DACA status removes both your work authorization and your protection from deportation.
Why Does It Matter to Have One Attorney for Criminal Defense and Immigration?
Most criminal defense attorneys handle the criminal case and refer immigration questions to a separate attorney. Most immigration attorneys do not handle criminal cases. This creates a gap: the criminal defense strategy gets built without considering immigration consequences, or the immigration attorney learns about the conviction after the damage is already done.
An attorney who practices both criminal defense and immigration law evaluates the full picture before any plea is entered. That means looking at the criminal charge, the client’s immigration status, and the specific plea alternatives that may resolve the criminal case without triggering a deportable conviction. California law supports this approach — Penal Code § 1016.3 requires prosecutors to consider immigration consequences in plea negotiations, but the defense attorney has to know what to ask for and which alternative dispositions avoid the immigration trigger.
This is the difference between resolving a case and protecting a future. A plea to a lesser charge that avoids jail may still qualify as an aggravated felony or a CIMT under federal law. A different plea — to a different charge, with different sentencing language — might resolve the same criminal case without the immigration penalty. But crafting that outcome requires an attorney who understands both systems well enough to see the trap before it closes.
Attorney Anthony J. Nuñes practices both criminal defense and immigration law from the Law Office of Anthony J. Nuñes. This is not a referral arrangement — it is one attorney covering both sides of the problem, with 26 years of experience across both practice areas. For noncitizens facing criminal charges in Orange County, that dual-practice capability means the criminal defense strategy and the immigration strategy are built together from day one, not stitched together after the fact.
What Should You Do If You Are a Noncitizen Facing Criminal Charges in California?
Time matters. The decisions made in the first days after an arrest shape both the criminal and immigration outcomes. If you are a noncitizen who has been arrested or charged with a crime in California, take these steps:
- Do not accept a plea deal without understanding the immigration consequences. Even a misdemeanor plea can trigger deportation. Before agreeing to any disposition — including diversion programs — ask your attorney to evaluate the immigration impact of every proposed resolution.
- Tell your attorney about your immigration status immediately. Your attorney needs this information to build a defense strategy that protects both your criminal case and your ability to remain in the United States. Attorney-client privilege protects this disclosure — your attorney cannot share your immigration status with the court, the prosecution, or law enforcement.
- Understand that a California expungement does not erase immigration consequences. Under federal immigration law, a conviction expunged under Penal Code § 1203.4 is still treated as a conviction for deportation and inadmissibility purposes. Post-conviction relief under Penal Code § 1473.7 — which allows vacating a conviction based on failure to meaningfully understand the immigration consequences of a plea — may provide a more effective path. But avoiding the problem in the first place is far easier than trying to fix it after the fact.
- Do not discuss your case with police or immigration agents without a lawyer present. Statements made during an arrest or investigation can affect both the criminal case and any future immigration proceedings. Exercise your right to remain silent and request an attorney.
- Contact an attorney who handles both criminal defense and immigration law. A coordinated defense — where one attorney understands both systems — prevents the gap between criminal resolution and immigration consequences that leads to irreversible outcomes.
Frequently Asked Questions
Can I be deported for a misdemeanor in California?
Yes. Federal immigration law does not follow California’s misdemeanor/felony classifications. Certain misdemeanors — including drug possession, theft offenses, domestic violence, and crimes involving moral turpitude — can trigger deportation or make you inadmissible to the United States. The immigration consequence is determined by the federal classification of the offense, not the California label.
Does a DUI affect immigration status?
A standard first-offense DUI is generally not classified as a crime involving moral turpitude on its own. However, a DUI with aggravating factors — such as injury to another person, an extremely high BAC, or a DUI involving controlled substances — can carry immigration consequences including deportation. Any DUI arrest also creates a criminal record that appears in immigration background checks and can affect discretionary decisions on visa renewals, green card applications, and naturalization.
Will an expungement protect me from deportation?
No. Federal immigration law does not recognize California expungements under Penal Code § 1203.4. A conviction that has been expunged is still treated as a conviction for immigration purposes. Post-conviction relief under Penal Code § 1473.7, which allows a court to vacate a conviction based on a defendant’s failure to meaningfully understand the immigration consequences of a plea, may provide a more effective path — but it requires a separate legal strategy and is not guaranteed.
Can I lose my green card because of a criminal conviction?
Yes. Lawful permanent residents can be placed in removal proceedings for convictions classified as aggravated felonies, crimes involving moral turpitude, drug offenses, domestic violence, and certain firearm offenses. A criminal conviction can also prevent you from becoming a U.S. citizen by disqualifying you from the “good moral character” requirement for naturalization.
What should I do if I am arrested and I am not a U.S. citizen?
Contact an attorney who handles both criminal defense and immigration law before accepting any plea offer or entering any diversion program. Do not discuss your immigration status with law enforcement. Under California law (Penal Code § 1016.5), the court is required to advise you that a guilty or no-contest plea may result in deportation, but this warning alone does not protect you — it is your attorney’s responsibility to evaluate the specific immigration impact and negotiate accordingly.
Why is having one attorney for both criminal defense and immigration important?
Criminal defense and immigration law operate under different systems with different rules. A plea deal that resolves a criminal case quickly may trigger automatic deportation under federal law. An attorney who practices in both areas can negotiate a disposition that satisfies the criminal case while avoiding or minimizing the immigration consequences — something that requires understanding both the California Penal Code and the federal Immigration and Nationality Act. When two separate attorneys handle the two sides, critical information often falls through the gap between them.
