Immigration Consequences of a California Criminal Case
If you are not a U.S. citizen, a criminal case has a second set of consequences that are decided by federal immigration law rather than by the judge in your case — and a resolution that looks good in criminal court can be the worse outcome once immigration law is applied to it. This is the part most often discovered too late.
Your lawyer has to advise you about this
Defense counsel has a constitutional duty to advise a noncitizen client about the immigration consequences of a plea. That duty exists because these consequences are severe and are not obvious from the criminal case itself. It is a floor, though — the real work is negotiating with them in mind from the beginning.
"Conviction" means something broader here
Federal immigration law has its own definition of a conviction, and it is wider than the state-court sense. A disposition that leaves no conviction on a state record — a diversion, a deferred structure, a later reduction — can still count as one for immigration purposes. This is the single most consequential misunderstanding in this area, and it is why immigration advice cannot wait until after the criminal case is resolved.
It is the category, not the seriousness
Immigration exposure follows defined statutory categories — offenses classified as aggravated felonies, crimes involving moral turpitude, controlled-substance offenses, domestic-violence offenses, and firearm offenses. Those categories do not track how serious a charge feels. A misdemeanor can carry consequences a more serious-sounding charge does not, which is why the analysis has to be done on the specific offense rather than by intuition.
Where the sentence length itself matters
For several categories, the consequence turns on the length of the sentence imposed — not on how much of it is actually served — with a threshold at one year. A sentence structured just below that threshold and one structured at it are entirely different immigration outcomes from the same charge. This is a durable, concrete thing a defense lawyer can negotiate for, and it is invisible unless someone is looking for it.
Detainers, and why the state matters
An immigration detainer can attach at the jail before the criminal case resolves at all. How much local jails cooperate with federal immigration authorities differs substantially among California, Arizona, and New Mexico, which means the same charge carries a different practical risk of immigration detention depending on where it was brought.
Why we handle both
This firm practices immigration law as well as criminal defense, so the immigration analysis happens while the criminal case is being negotiated rather than as a post-mortem afterward. If you are not a U.S. citizen, say so at the first conversation — it changes what a good resolution looks like. Se habla español.
Criminal Defense law in California
California gives a defense lawyer more structural room than most states — and runs your driving case on a separate track from your criminal case.
- Felony or misdemeanor — often a choice: Many California offenses are 'wobblers': the same conduct can be charged as either a felony or a misdemeanor, and the court has authority to reduce a charged felony to a misdemeanor. Which side of that line a case lands on drives almost everything that follows, and it is one of the things a defense lawyer argues about earliest.
- Two cases at once in a DUI: A California DUI runs as two separate matters — the criminal case in court, and an administrative license action the DMV brings on its own timeline, with its own hearing and its own standard. You can win one and lose the other. The window to demand the DMV hearing is short and unforgiving, so it is the first thing to handle.
- Where a felony sentence is served: After realignment, many California felony sentences are served in county jail under supervision rather than in state prison. This surprises people, and it changes what a negotiated resolution can look like.
- The felony line keeps moving: California voters have repeatedly redrawn the felony/misdemeanor line for drug and theft offenses by ballot initiative, so how the same conduct is charged depends on when it happened and on the initiative landscape in force.
- Resolving a case without a conviction: California has an unusually broad set of statutory diversion paths — including drug, mental-health, and veteran diversion — that can resolve a case without a conviction. If you are not a U.S. citizen, ask specifically how a diversion is treated under federal immigration law, because the answer is not always the same as the state answer.
- Bail and getting out: A California court must consider your ability to pay before setting money bail that would keep you in custody.
Frequently asked questions
Can I be deported for a misdemeanor?
Possibly. Immigration consequences follow defined statutory categories rather than how serious a charge sounds, so some misdemeanors carry exposure that more serious-sounding charges do not. The analysis has to be done on the specific offense.
If the case is dismissed or diverted, am I safe?
Not necessarily. Federal immigration law defines "conviction" more broadly than state law does, and a disposition that leaves no state conviction can still count as one. This is the most common and most costly misunderstanding in this area.
Does it matter how long the sentence is?
For several categories, yes — the consequence can turn on the length of the sentence imposed rather than time actually served, with a threshold at one year. A sentence structured just under that line can be a completely different immigration outcome.
I have a green card. Does this apply to me?
Yes. Lawful permanent residents can be placed in removal proceedings based on certain convictions. Having a green card does not remove the exposure, and it is worth advice before resolving any case.
Should I tell my criminal lawyer I am not a citizen?
Yes, at the first conversation. It is confidential, and it changes what a good resolution looks like. A defense lawyer who does not know cannot negotiate around consequences you cannot afford.
California law — what people ask
Can a felony be reduced to a misdemeanor in California?
For a large category of offenses, yes. California calls them wobblers: the same conduct can be charged either way, and the court has authority to reduce a charged felony to a misdemeanor. Which side of that line a case ends on drives the exposure, where any sentence is served, and most of the consequences that outlast the case — so it is argued about early rather than at the end.
Why does a California DUI involve two separate cases?
Because the criminal charge and your driving privilege are decided separately. The DMV runs its own administrative action with its own hearing, its own standard and its own timeline, and you can win one and lose the other. The window to demand the DMV hearing is short and unforgiving, which makes it the first thing to handle in a new case.
Will a California felony sentence be served in state prison?
Not necessarily. After realignment many felony sentences are served in county jail under supervision rather than in state prison. It surprises people, and it changes what a negotiated resolution can realistically look like.
Can a California case be resolved without a conviction?
California has an unusually broad set of statutory diversion routes — including drug, mental-health and veteran diversion — which can resolve an eligible case without a conviction. Eligibility rules are specific and they move, so they get checked against the current rules rather than assumed. If you are not a U.S. citizen, ask separately how federal immigration law treats that outcome; the answer is not always the same.
Has California changed what counts as a felony for drug and theft cases?
Repeatedly, by ballot initiative, and in both directions. That means how the same conduct is charged can depend on when it happened and on which initiative framework is in force. It is one of the few areas where advice more than a couple of years old is genuinely unreliable.
Think you may have a case?
The case review takes about two minutes. It's free and confidential, with no obligation.
