Two Systems That Collide
The United States criminal justice system and the immigration system operate independently — but a conviction in one can trigger devastating consequences in the other. A non-citizen who pleads guilty to a criminal charge may receive a light sentence from the criminal court while simultaneously triggering mandatory deportation under immigration law. These consequences are often invisible at the time of the plea, and many defense attorneys fail to advise their clients about them.
For families where a loved one is both a non-citizen and facing or serving a criminal conviction, understanding the immigration consequences is urgent.
The Categories of Convictions That Trigger Immigration Consequences
Aggravated Felonies
The term "aggravated felony" in immigration law is deeply misleading — it includes many offenses that are not felonies under state law and are not considered particularly aggravated in ordinary usage. Under 8 U.S.C. § 1101(a)(43), aggravated felonies include:
- Murder, rape, and sexual abuse of a minor
- Drug trafficking offenses
- Theft or burglary with a sentence of one year or more
- Fraud or deceit offenses with a loss to victims exceeding $10,000
- Money laundering exceeding $10,000
- Crimes of violence with a sentence of one year or more
- Running a prostitution business
A conviction for an aggravated felony results in mandatory deportation with almost no exceptions, permanent bar to most immigration benefits, and a permanent bar to returning to the US after removal.
Crimes Involving Moral Turpitude (CIMTs)
This is a vague and broad category that courts have struggled to define consistently. Generally includes fraud, theft, violent crimes, and crimes involving dishonesty. A single CIMT can make a non-citizen deportable or inadmissible depending on when it was committed relative to admission and the sentence imposed.
Controlled Substance Offenses
Almost any drug conviction — including simple possession in many cases — triggers deportability. This includes state convictions. A single marijuana possession conviction can make a green card holder deportable even if marijuana is legal in the state where the conviction occurred, because federal immigration law controls.
Domestic Violence and Firearms Offenses
Domestic violence convictions, stalking, violations of protective orders, and firearms trafficking offenses all trigger deportability for non-citizens.
Who Is Affected
Immigration consequences apply to all non-citizens — not just undocumented people:
- Green card holders (permanent residents): Can be deported for qualifying convictions even after decades of lawful residence
- Visa holders: Student visas, work visas, tourist visas are all subject to revocation
- DACA recipients: A criminal conviction typically terminates DACA eligibility
- Asylum seekers and refugees: Certain convictions can bar asylum claims or terminate refugee status
- Those applying for citizenship: Criminal convictions can permanently bar naturalization
The Padilla Obligation
In Padilla v. Kentucky (2010), the Supreme Court held that criminal defense attorneys are constitutionally required to advise non-citizen clients about the deportation consequences of a guilty plea. Failure to do so can constitute ineffective assistance of counsel — meaning a conviction based on a guilty plea where the defendant wasn't informed of immigration consequences may be challengeable.
If your family member pleaded guilty without being told the plea would lead to deportation, this may be grounds for post-conviction relief — both in the criminal court (to vacate the plea) and in immigration proceedings.
What Families Can Do
- Determine whether the conviction falls into a deportable category — this requires review by an immigration attorney familiar with criminal law
- If a plea was entered without proper Padilla advice, investigate a motion to withdraw the plea
- In immigration removal proceedings, certain defenses and waivers may be available depending on the circumstances
