Short answer: A criminal charge or conviction can hurt a non-citizen's immigration case in two different ways: it can make someone inadmissible (blocked from a visa, a green card, or re-entry) and/or deportable (removable even with a valid green card). Immigration law also defines some crimes far more broadly than criminal law does — a state "misdemeanor" can count as an "aggravated felony" for immigration purposes. Because these rules are technical and unforgiving, any non-citizen who is arrested, charged, or asked to sign a plea deal should get advice from a lawyer who understands both criminal and immigration law ("crimmigration") before entering any plea.
Two different questions: inadmissible vs. deportable
Inadmissibility (INA § 212(a)(2)) applies when someone is trying to enter the country, applies for a visa abroad, or applies to adjust status to a green card from inside the U.S. Certain convictions — and sometimes even an admission of the elements of a crime, with no conviction — can trigger this ground.
Deportability (INA § 237(a)(2)) applies to someone already lawfully in the U.S., including lawful permanent residents. Certain convictions after admission can make even a long-time green card holder removable.
The two lists overlap but are not identical; a person can be inadmissible without being deportable, or the reverse. That is why the same conviction can block a green card application, block naturalization, or trigger removal, depending on the person's current status. The full lists appear in the Immigration and Nationality Act (govinfo.gov) and the USCIS Policy Manual (uscis.gov); an immigration attorney can map a specific conviction to the specific ground.
"Conviction" means more in immigration law than you might think
Immigration law has its own federal definition of "conviction" (INA § 101(a)(48)(A)). A guilty or no-contest plea combined with some court-ordered punishment or restraint can count as a conviction for immigration purposes — even if the state calls it a "diversion," the charge was later dismissed after probation, no formal finding of guilt was entered, or the record was expunged. This is a common trap: a criminal defense lawyer unfamiliar with immigration law may steer a client toward a plea that looks favorable in criminal court (probation, no jail time, eventual dismissal) without realizing immigration law will still treat it as a conviction.
Crimes involving moral turpitude (CIMT)
"Crime involving moral turpitude" is an immigration-law term with no single statutory definition. Case law from immigration courts and the Board of Immigration Appeals describes it as conduct that is inherently base, vile, or depraved and contrary to accepted morality — commonly including many theft, fraud, and intent-to-injure offenses. Whether a specific state offense qualifies takes legal analysis of the statute's wording, not a label from sentencing.
A narrow "petty offense exception" excuses a single CIMT from triggering inadmissibility if the maximum possible sentence was one year or less and the person was not actually sentenced to more than six months. It applies to only one qualifying offense, not two or more.
Aggravated felonies: a misleadingly broad term
"Aggravated felony" (INA § 101(a)(43)) sounds like it should mean serious violent crime, but in immigration law it is a defined list of more than 20 categories, some triggered by a sentence length (often one year or more, even if suspended) or a dollar-loss threshold rather than by violence. So some state theft, fraud, or drug offenses that are misdemeanors under state law can still be "aggravated felonies" for immigration purposes.
An aggravated felony conviction is among the most severe outcomes in immigration law: it generally makes a person deportable with very limited defenses, eliminates eligibility for most relief from removal, bars asylum eligibility, and permanently bars establishing "good moral character" for naturalization (for offenses on or after November 29, 1990). This label depends on precise statutory wording and sentence details, not on what the charge is called, so only a lawyer who checks the specific statute and sentence can say whether it applies.
Controlled-substance and firearm offenses
Drug offenses are treated especially harshly. A conviction for violating a state, federal, or foreign controlled-substance law can trigger both inadmissibility and deportability. Even an admission of the elements of a drug offense — with no arrest or conviction — can support inadmissibility. A narrow exception in the deportability ground covers a single small-quantity marijuana possession offense; other drug offenses and the inadmissibility ground generally do not carry it. Because drug policy keeps shifting, confirm the current rule with an immigration attorney rather than assuming an exception applies. Drug trafficking is separately listed as an aggravated felony.
Immigration law also has its own deportability ground for firearm offenses (INA § 237(a)(2)(C)): a conviction for buying, selling, using, owning, possessing, or carrying certain firearms, after admission, can make even a green card holder deportable, regardless of whether it also qualifies as a CIMT or aggravated felony.
Why crimmigration-aware criminal defense matters
In Padilla v. Kentucky, 559 U.S. 356 (2010), the U.S. Supreme Court held that the Sixth Amendment right to effective counsel requires a criminal defense attorney to advise a non-citizen client about the immigration consequences of a guilty plea — telling the client removal will result if the law is clear, or may result if it is unclear. An attorney who says nothing, or gives wrong advice, may have provided deficient representation, but fixing that after a plea is entered is far harder than getting it right the first time.
In practice: plea negotiations are often the single most important moment in the whole immigration case. A slightly different charge or sentence length can sometimes avoid an aggravated-felony or CIMT classification for the same underlying conduct. Many defense offices now consult an immigration attorney before a plea is signed — non-citizens should ask for that if it is not offered.
Waivers and relief: sometimes there is a path forward
A criminal record does not automatically end every case. Depending on the ground involved, waivers of certain inadmissibility grounds or cancellation of removal (for some long-term residents without a disqualifying aggravated felony) may exist, usually requiring hardship to qualifying relatives or other rules tied to exactly which ground applies. Do not assume a waiver applies to you — confirm current eligibility with an immigration attorney, USCIS (uscis.gov), or EOIR (justice.gov/eoir).
What to do if you or a family member is a non-citizen facing a charge
Tell your criminal defense attorney your immigration status immediately — even with a green card, even if status is unclear.
Do not accept any plea, deferred adjudication, or diversion program before getting an immigration-consequences assessment. "No jail time" does not mean "immigration-safe."
Ask your defense attorney to consult, or refer you to, an immigration attorney before any plea is entered.
Do not speak with immigration officers, including ICE, without a lawyer, and do not sign any immigration document you do not fully understand.
If already in removal proceedings, calendar every deadline the court gives you. Missing a hearing can trigger an in-absentia removal order, and appeal or motion-to-reopen deadlines are short and strictly enforced — confirm the exact deadline with your attorney or the court.
Beware of "notario" fraud. Immigration legal advice must come from a licensed attorney or a Department of Justice-accredited representative — verify one through EOIR's recognition and accreditation program before paying anyone.
Frequently asked questions
Can I be deported for a crime even though I have a green card?
Yes. Lawful permanent resident status does not protect against removal. Certain convictions after admission — including some aggravated felonies, controlled-substance offenses, firearm offenses, and crimes involving moral turpitude — can make a green card holder deportable.
If my case was dismissed after a diversion program, does immigration still count it as a conviction?
Often yes. A guilty or no-contest plea combined with court-ordered punishment or restraint can count as a conviction under federal immigration law even if the criminal case was later dismissed under a state diversion program. Do not assume a dismissal erases the immigration record without confirming with an immigration attorney.
Is "aggravated felony" the same as a felony under state law?
No. It is a federal immigration-law term covering more than 20 specific categories, some of which are misdemeanors under state law. Whether a conviction qualifies depends on the exact statute and sentence, not on the state's label for the charge.
Does my defense lawyer have to tell me about immigration consequences before I plead guilty?
Under Padilla v. Kentucky, yes: a criminal defense attorney has a constitutional duty to advise a non-citizen client about the immigration consequences of a guilty plea, including saying removal is likely if the law is clear, or may result if it is unclear.
Are all drug offenses treated the same way for immigration purposes?
No. Possession, distribution, and trafficking trigger different consequences, and a narrow exception exists for a single small-quantity marijuana possession offense. Because drug policy keeps changing, confirm the current treatment of a specific offense with an immigration attorney rather than assuming.
