Immigration Consequences of a Federal Conviction

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

For a noncitizen facing a federal charge, the criminal case and the immigration case are inseparable. A conviction can do more than impose a sentence — it can end a person’s lawful status and result in removal from the United States, sometimes with little or no possibility of relief. For many noncitizen defendants, the immigration consequence is the most important issue in the entire case, outweighing even the length of a prison term.

This guide explains the immigration consequences of a federal conviction — the grounds of deportability, the severe category of “aggravated felony,” how crimes involving moral turpitude and controlled-substance offenses are treated, and why the precise charge of conviction is so often decisive. It is grounded in 8 U.S.C. § 1227, the Supreme Court’s decision in Padilla v. Kentucky, and the case law applying the categorical approach. Elizabeth Franklin-Best, P.C. handles federal criminal defense nationwide and treats a client’s immigration exposure as a core element of the defense, not an afterthought. Principal attorney Elizabeth Franklin-Best is listed in Best Lawyers in America 2026 as a “Best Lawyer” in Appellate Practice and ranked by Chambers USA 2026 for Litigation: White-Collar Crime & Government Investigations — recognition built in precisely the kind of work where the charge of conviction, and therefore the immigration outcome, gets decided. Across more than 330 federal proceedings and over 100 appeals in courts nationwide, she has seen how a single count of conviction or a loss figure entered without objection can reshape a client’s future long after the criminal sentence is served. Managing Director Christopher Zoukis, the firm’s federal prison and reentry authority, informs the post-sentencing side of that analysis.

If you are a noncitizen facing a federal charge — or your family member is — the firm offers a paid, one-hour initial consultation to review the criminal exposure and the immigration stakes together.

Quick Answer: Immigration Consequences

Question	Answer
Can a federal conviction get a noncitizen deported?	Yes. Under 8 U.S.C. § 1227, many convictions make a noncitizen deportable, and for a broad class of offenses removal is, as the Supreme Court has said, nearly automatic.
What is an aggravated felony?	A category defined in 8 U.S.C. § 1101(a)(43). It need not be “aggravated” or even a felony in the ordinary sense. It makes a noncitizen deportable and ineligible for most discretionary relief.
When is fraud an aggravated felony?	When the offense involves fraud or deceit and the loss tied to the count of conviction exceeds $10,000 — the rule of 8 U.S.C. § 1101(a)(43)(M)(i), measured under Nijhawan v. Holder from sentencing-phase facts like stipulations and restitution.
Does a green card protect me?	No. A lawful permanent resident can be placed in removal proceedings and lose status based on a qualifying conviction.
Why does the exact charge matter so much?	Immigration courts use the categorical approach, comparing the elements of the offense of conviction to the immigration category. The precise charge can decide whether removal is triggered.
Should immigration be considered in my criminal case?	Yes. Under Padilla v. Kentucky, counsel must advise on deportation risk, and the criminal resolution should be shaped with the immigration stakes in view.

Key Takeaways

• A criminal conviction is the trigger for immigration consequences; removal proceedings are civil but intimately tied to the criminal process.
• Padilla v. Kentucky holds that defense counsel must advise a noncitizen client about the deportation risk of a guilty plea.
• The criminal grounds of deportability in 8 U.S.C. § 1227(a)(2) include crimes involving moral turpitude, aggravated felonies, controlled-substance offenses, firearms offenses, and domestic-violence offenses.
• An “aggravated felony” under 8 U.S.C. § 1101(a)(43) need not be aggravated or a felony in the ordinary sense; it makes a noncitizen deportable and ineligible for most discretionary relief.
• Many federal fraud offenses can qualify as aggravated felonies or crimes involving moral turpitude.
• Under Nijhawan v. Holder, the $10,000 fraud-loss threshold is a circumstance-specific fact — loss stipulations and restitution orders tied to the count of conviction can decide it.
• An aggravated felony does more than make a person deportable: it bars cancellation of removal and asylum and triggers mandatory detention under 8 U.S.C. § 1226(c).
• Controlled-substance convictions carry particularly severe and layered immigration consequences.
• Immigration courts use the categorical approach, comparing the elements of the offense of conviction to the immigration category.
• Because the analysis turns on the elements of the precise charge, charge selection and plea structure can determine whether removal is triggered.
• A green card does not protect against a removable conviction; a lawful permanent resident can lose status.
• The criminal defense and the immigration analysis must be coordinated from the start, while the conviction is not yet final.

Why a Conviction Can Mean Removal

The immigration consequences of a conviction are not punishment imposed by the criminal court. Removal proceedings are civil, and they take place in a separate immigration system. But the two systems are tightly linked: a criminal conviction is the trigger that sets the immigration consequence in motion.

The Supreme Court recognized exactly this in Padilla v. Kentucky. The Court described deportation as a “particularly severe penalty” that, while not technically a criminal sanction, is “intimately related to the criminal process.” It observed that, for a broad class of noncitizen offenders, removal has become “nearly an automatic result” of a conviction. On that basis, the Court held that defense counsel has a Sixth Amendment duty to advise a noncitizen client about the deportation risk a guilty plea carries.

Padilla, 559 U.S. 356 (2010), did more than create a duty to warn. The Court drew a line that matters enormously in practice: where the deportation consequence of a plea is truly clear — as it is for many federal drug and fraud offenses — counsel must give correct advice about that consequence, and where the law is uncertain or unsettled, counsel must at minimum flag the risk of adverse immigration consequences. A vague “this might affect your status” does not discharge the duty when the statute plainly commands removal.

The Supreme Court has also addressed what happens when that advice fails. In Jae Lee v. United States, 582 U.S. 357 (2017), a defendant pleaded guilty after his lawyer wrongly assured him the plea would not lead to deportation. The Court held that he could establish prejudice under Strickland v. Washington by showing a reasonable probability that, properly advised, he would have rejected the plea and insisted on trial — even without a viable trial defense — because deportation was the determinative issue in his decision and contemporaneous evidence backed that up. Claims of this kind are generally raised through a § 2255 motion asserting ineffective assistance of counsel, and they are far harder to win than getting the advice right the first time.

The practical meaning of Padilla is that the immigration stakes cannot be treated as someone else’s problem to sort out later. They are part of the criminal case from the beginning. Decisions made in the criminal proceeding — what charge a person is convicted of, the structure of a plea, even the length of a sentence — determine, in immigration court, whether the person can stay in the country.

Grounds of Deportability Under § 1227

The grounds on which a conviction can make a noncitizen deportable are set out in 8 U.S.C. § 1227. The criminal grounds in § 1227(a)(2) are the ones that matter most in a criminal case, and they fall into several categories:

• Crimes involving moral turpitude. A noncitizen can be deportable for a crime involving moral turpitude committed within a defined period after admission, or for multiple such crimes at any time.
• Aggravated felonies. A noncitizen convicted of an “aggravated felony” at any time after admission is deportable — the most severe category, discussed below.
• Controlled-substance offenses. A conviction relating to a controlled substance is a ground of deportability, subject to a narrow exception.
• Firearms offenses. Certain firearm and destructive-device convictions are grounds of deportability.
• Domestic violence and related offenses. Convictions for domestic violence, stalking, and child abuse, neglect, or abandonment are separate grounds.

A separate body of law — the grounds of inadmissibility — governs a noncitizen seeking admission, a visa, or adjustment to permanent residence. The deportability and inadmissibility frameworks overlap but are not identical, and which one applies depends on the person’s status and what they are seeking. Both must be considered in a full analysis.

Applied Insight: The immigration grounds rarely map neatly onto the labels used in the criminal code. An offense that sounds minor can fall within a serious immigration category, and an offense that sounds serious may not. That mismatch is why a conviction’s immigration effect must be analyzed on its own terms, not assumed from the criminal charge’s name.

Aggravated Felonies: The Most Severe Category

The “aggravated felony” is the most consequential category in immigration law, and the term is badly misleading. An aggravated felony need not be “aggravated” in any ordinary sense, and it need not even be a felony — some offenses classified as misdemeanors under criminal law can qualify.

The category is defined by a long list in 8 U.S.C. § 1101(a)(43), which contains roughly two dozen subsections. It includes offenses such as murder, drug trafficking, certain firearm offenses, a theft offense for which the term of imprisonment is at least one year, and a fraud or deceit offense in which the loss to the victim or victims exceeds a defined dollar threshold — a category that captures many federal white-collar fraud offenses.

What makes the aggravated-felony category so severe is the double consequence. A noncitizen convicted of an aggravated felony is not only deportable — the conviction also makes the person ineligible for most forms of discretionary relief from removal, including common avenues like cancellation of removal. As courts have put it, for an aggravated felon, removal can become close to a foregone conclusion. An aggravated-felony conviction can also carry mandatory immigration detention and a streamlined removal process.

Two details deserve emphasis. First, because the fraud-offense category turns on a loss threshold, and the theft category turns on a one-year sentence, the numbers in a case — the loss amount the conviction rests on, the exact sentence imposed — can determine whether an offense is an aggravated felony. Second, even a sentence of “one year” can be the line: a sentence set even slightly below that mark can change the immigration outcome. These are the kinds of details that a careful criminal defense can sometimes influence.

The $10,000 Fraud Aggravated Felony: § 1101(a)(43)(M)

For the clients this firm serves, one subsection towers over the rest of the list. Under 8 U.S.C. § 1101(a)(43)(M)(i), an offense that “involves fraud or deceit” is an aggravated felony if the loss to the victim or victims exceeds $10,000. A companion clause, (M)(ii), covers tax evasion under 26 U.S.C. § 7201 where the revenue loss to the government exceeds the same figure. Because federal fraud indictments routinely allege losses far beyond $10,000, a noncitizen convicted of mail, wire, bank, or securities fraud is very often an aggravated felon in the eyes of immigration law — with every form of relief that label forecloses.

How the $10,000 figure is measured was settled in Nijhawan v. Holder, 557 U.S. 29 (2009). The loss threshold is not an element of the offense that must appear in the statute; it is a “circumstance-specific” fact about how the crime was committed on the particular occasion, which an immigration judge may find from sentencing-phase material such as a defendant’s own stipulation or a restitution order. But Nijhawan carries an equally important limit: the loss must be tied to the specific counts covered by the conviction — not to acquitted counts, dismissed counts, or general relevant conduct — and the government must prove it by clear and convincing evidence.

Tax offenses beyond § 7201 are swept in as well. In Kawashima v. Holder, 565 U.S. 478 (2012), the Supreme Court held that willfully filing a false tax return, and aiding the preparation of one, under 26 U.S.C. §§ 7206(1) and (2) are crimes “involving fraud or deceit” under clause (M)(i) — so they become aggravated felonies whenever the government’s revenue loss exceeds $10,000, even though § 7206 appears nowhere in the tax-specific clause. A noncitizen professional weighing a “lesser” false-return plea to avoid an evasion charge needs to understand that the immigration consequence may be identical.

Applied Insight: In a fraud case, the documents that decide the immigration outcome are often drafted with only the Sentencing Guidelines in mind. A loss stipulation negotiated to position a Guidelines range, or a restitution figure entered without objection, can quietly supply the proof that the loss on the count of conviction exceeded $10,000. Defending a noncitizen means treating every number that enters the record of conviction as an immigration document, because under Nijhawan, that is exactly what it becomes.

Obstruction, Money Laundering, and Other White-Collar Traps

The fraud clause is not the only aggravated-felony provision aimed at financial cases. Three others recur in white-collar prosecutions:

• Money laundering. Clause (D) covers offenses described in 18 U.S.C. §§ 1956 and 1957 if the amount of the funds exceeded $10,000.
• Obstruction, perjury, and witness bribery. Clause (S) covers offenses relating to obstruction of justice, perjury or subornation of perjury, or bribery of a witness, where the term of imprisonment is at least one year.
• Commercial bribery, counterfeiting, and forgery. Clause (R) reaches these offenses, again with a one-year imprisonment trigger.

The obstruction clause grew broader recently. In Pugin v. Garland, 599 U.S. 600 (2023), the Supreme Court held that an offense may “relate to obstruction of justice” under clause (S) even if no investigation or proceeding was pending when the obstructive conduct occurred, reasoning that obstruction is often most effective precisely when it stops an investigation from ever beginning. White-collar defendants frequently face obstruction counts alongside fraud charges, and after Pugin, an obstruction plea carrying a sentence of a year or more can create aggravated-felony exposure on its own — even where the fraud counts are resolved below the $10,000 line.

One more trap deserves mention: for the one-year clauses, immigration law counts the sentence imposed, including any portion suspended. A “365 days, suspended” disposition that feels like a victory in criminal court is a one-year term of imprisonment in immigration court.

Moral Turpitude and Controlled-Substance Offenses

Two other categories arise constantly.

A crime involving moral turpitude is a category traditionally understood to involve fraud, dishonesty, or conduct that is inherently base or depraved. A single such crime can make a noncitizen deportable if it was committed within a defined period after admission and is serious enough, and multiple such crimes can make a person deportable regardless of timing. Many federal fraud offenses are treated as crimes involving moral turpitude, which is why white-collar convictions carry real immigration risk.

Controlled-substance offenses are treated with particular severity in immigration law. A conviction relating to a controlled substance is generally a ground of deportability, with only a narrow exception for a single offense involving simple possession of a small amount of marijuana. Many drug convictions also independently qualify as aggravated felonies. For a noncitizen, a federal drug charge therefore carries layered immigration exposure that must be assessed carefully.

The Categorical Approach and Charge Selection

Understanding how immigration courts decide whether a conviction triggers a consequence is essential, because it reveals where the leverage lies. Courts generally use what is called the “categorical approach.”

Under the categorical approach, an immigration court does not re-examine what the person actually did. Instead, it compares the elements of the offense of conviction to the generic federal definition of the immigration category. As the Supreme Court has explained, because immigration consequences are predicated on convictions rather than conduct, the analysis looks to the statutory definition of the offense, not the underlying facts. If the elements of the offense of conviction match or fall within the immigration category, the consequence attaches; if the offense is broader than the category, it may not.

The leading modern statement is Moncrieffe v. Holder, 569 U.S. 184 (2013). There the Supreme Court explained that the question is whether the statute of conviction categorically fits within the generic federal definition, and — critically — that a court must presume the conviction rested on nothing more than the least of the acts the statute criminalizes. If even that minimum conduct falls outside the immigration category, the conviction does not trigger the consequence, no matter what the person actually did. The presumption has one check: there must be a realistic probability, not just a theoretical possibility, that the statute would be applied to the broader conduct. The approach is not universal, either — as Nijhawan shows, certain provisions, like the $10,000 loss threshold, call for circumstance-specific facts rather than an elements comparison, so counsel must know which mode governs each category.

This is the single most important strategic point in the entire area. Because the analysis turns on the elements of the precise offense of conviction, the choice of charge — which statute, which subsection, what the plea actually establishes — can be the difference between a conviction that triggers removal and one that does not. A defense that understands the categorical approach can sometimes structure a resolution around a charge whose elements do not match a removable category, or whose numbers fall on the safer side of a threshold.

Applied Insight: For a noncitizen client, the immigration analysis should drive the criminal strategy, not follow it. A plea that looks favorable on the criminal side — a shorter sentence, a familiar charge — can be catastrophic in immigration court if its elements match an aggravated felony. The strongest outcomes come from treating “a conviction that does not trigger removal” as a primary goal from day one.

Lawful Permanent Residents Are Not Immune

A common and dangerous misconception is that holding a green card protects a person from the immigration consequences of a conviction. It does not. A lawful permanent resident can be placed in removal proceedings and lose their status based on a qualifying conviction, just as a visa holder or other noncitizen can.

Long residence, family ties, and deep roots in the United States do not change the basic rule, although they can matter to whatever discretionary relief may be available. And where the conviction is an aggravated felony, the very relief that long-residing permanent residents would otherwise rely on is often foreclosed. A green card is valuable, but it is not a shield against a removable conviction.

It is also worth understanding what counts as a “conviction” for immigration purposes. Immigration law has its own definition, which can reach certain dispositions — including some that involve withheld adjudication paired with a plea and a penalty — that a person might not think of as a conviction at all. A disposition that resolves a criminal case favorably can still carry immigration consequences if it satisfies that definition.

Inadmissibility and the Bars to Relief

Deportability is only half of the framework. A separate statute, 8 U.S.C. § 1182, lists the grounds of inadmissibility that apply when a noncitizen seeks admission, a visa, or adjustment to permanent residence. The two lists diverge in ways that catch people by surprise. A single crime involving moral turpitude, for example, triggers inadmissibility no matter when it was committed (subject to a narrow petty-offense exception), while the comparable deportability ground requires commission within five years of admission and a possible sentence of a year or longer. The upshot: a conviction that does not make a person deportable can still make them inadmissible — a problem that surfaces the first time they travel abroad and present themselves for reentry, or apply to adjust status.

For an aggravated felony, the statutory bars stack on top of removability itself. Under the Immigration and Nationality Act, the conviction:

• bars cancellation of removal, the discretionary relief long-term permanent residents would otherwise seek, under 8 U.S.C. § 1229b(a)(3);
• counts automatically as a “particularly serious crime” that bars asylum under § 1158(b)(2)(B)(i);
• bars withholding of removal where the aggregate term of imprisonment is at least five years, under § 1231(b)(3)(B);
• permanently precludes the good moral character finding that naturalization requires, under § 1101(f)(8); and
• subjects the person to mandatory immigration detention during removal proceedings under § 1226(c), generally without an individualized bond hearing.

A noncitizen removed after an aggravated-felony conviction is also inadmissible permanently, and returning without permission becomes its own serious federal felony with enhanced penalties. The pattern is unmistakable: once the aggravated-felony label attaches, the law is engineered to make removal swift, detention mandatory, and return impossible. That is why so much of the defense effort described on this page is aimed at keeping the label from attaching at all.

Coordinating Criminal and Immigration Strategy

Because the criminal case drives the immigration result, the two have to be handled together. In practice, that means the criminal defense and the immigration analysis should be coordinated from the start of the case — often through close work between criminal defense counsel and immigration counsel.

On the criminal side, the defense can analyze how each potential charge and resolution would be treated under the immigration categories, identify which outcomes avoid a removable conviction where that is achievable, and negotiate toward a charge or sentence structure that protects the client’s status. None of this is a guarantee — the immigration consequences of some conduct cannot be avoided — but for many cases there is meaningful room to shape the outcome, and that room exists only before the conviction is final.

Elizabeth Franklin-Best, P.C. analyzes the immigration exposure of a federal criminal case as part of its defense strategy and works with immigration counsel so that the criminal resolution accounts for the immigration stakes. The goal is a defense that treats a client’s ability to remain in the country as the priority it usually is.

Frequently Asked Questions

How Our Firm Helps Noncitizen Defendants

Defending a noncitizen well means running two analyses at once. Before any plea discussion, we map each charge the government could pursue against the aggravated-felony clauses, the moral-turpitude grounds, and the inadmissibility list, so we know which resolutions carry removal and which do not. Where the case allows it, we negotiate the variables that decide the immigration outcome — the count of conviction, the loss figure tied to that count, the sentence relative to the one-year clauses — and we work alongside the client’s immigration counsel rather than handing the problem off after judgment. Immigration exposure is one piece of the broader picture mapped in our guide to the collateral consequences of a federal conviction.
