Alien smuggling, harboring and other federal immigration crimes

What does the law make illegal?

Smuggling, transporting and harboring, 8 U.S.C. § 1324

Federal immigration law uses the word "alien" for anyone who is not a U.S. citizen or national (8 U.S.C. § 1101(a)(3)). Section 1324(a)(1)(A) makes it a crime for any person, including a U.S. citizen, to do any of the following (8 U.S.C. § 1324):

• Bring in. Knowing someone is an alien, bring or try to bring them into the United States anywhere other than a designated port of entry (§ 1324(a)(1)(A)(i)).
• Transport. Knowing, or in reckless disregard of the fact, that someone came, entered or remains here unlawfully, transport or move them inside the United States "in furtherance of" that violation (§ 1324(a)(1)(A)(ii)).
• Harbor. With the same knowledge or reckless disregard, conceal, harbor or shield them from detection in any place, including a building or vehicle (§ 1324(a)(1)(A)(iii)).
• Encourage or induce. Encourage or induce someone to come to, enter or live in the United States, knowing or in reckless disregard of the fact that it is or will be unlawful (§ 1324(a)(1)(A)(iv)).
• Conspire or help. Agree with others to do any of these, or aid or abet them (§ 1324(a)(1)(A)(v)).

Courts generally describe "reckless disregard" as being aware of a substantial risk that the passenger or tenant was here unlawfully and choosing to ignore it. In United States v. Hansen, 599 U.S. 762 (2023), the Supreme Court read "encourages or induces" narrowly: it covers only purposely soliciting or helping specific acts known to violate federal law, not general speech or advocacy. Read that way, the Court held the clause is not unconstitutionally overbroad.

A separate offense, § 1324(a)(2), covers bringing or trying to bring someone into the country at all, even at a port of entry, knowing or in reckless disregard of the fact that they don't have permission to come. It is also a crime to knowingly hire at least 10 people in a 12-month period knowing they are unauthorized workers who were smuggled in (§ 1324(a)(3)).

Illegal entry, marriage fraud and business fraud, 8 U.S.C. § 1325

Under 8 U.S.C. § 1325(a), a non-citizen commits illegal entry by (1) entering or trying to enter anywhere other than where immigration officers designate, (2) avoiding examination or inspection by immigration officers, or (3) entering or trying to enter by a willfully false or misleading statement or by willfully hiding an important fact. Simply being in the country without status is generally a civil immigration matter, not this crime. Coming back after a removal is a separate, more serious crime, covered on our illegal reentry page.

• Marriage fraud (§ 1325(c)): knowingly entering into a marriage to get around the immigration laws.
• Business fraud (§ 1325(d)): knowingly setting up a business to get around the immigration laws.

Fake and fraudulent immigration documents, 18 U.S.C. § 1546

Section 1546(a) covers knowingly making, altering or counterfeiting a visa, green card, border crossing card or other document used for entry or as proof of permission to stay or work; using, possessing or receiving one knowing it is fake or was obtained by fraud; impersonating someone or using a false name in an application; and knowingly making a false statement under oath, or under penalty of perjury, about a material fact in an immigration application (18 U.S.C. § 1546). Section 1546(b) separately covers using a false or borrowed ID document, or a false attestation, to satisfy the employment-verification (Form I-9) requirements.

What are the penalties?

• Forfeiture: vehicles, boats and planes used in smuggling, and the proceeds, can be taken (8 U.S.C. § 1324(b); 18 U.S.C. § 982(a)(6)).
• Fines: up to $250,000 per felony count (18 U.S.C. § 3571).
• Supervised release: up to 5 years when the maximum is life, up to 3 years for most other felonies here, and up to 1 year for a 2-year offense (18 U.S.C. § 3583(b)).

How does sentencing work for this charge?

Smuggling, transporting and harboring are sentenced under USSG §2L1.1. The base offense level is usually 12 (higher for some convictions under 8 U.S.C. § 1327). Then:

• Not for profit, or only a spouse or child: −3 (§2L1.1(b)(1)).
• Number of people: +3 for 6–24, +6 for 25–99, +9 for 100 or more; the defendant isn't counted (§2L1.1(b)(2)).
• Prior immigration felonies: +2 or +4 (§2L1.1(b)(3)).
• Unaccompanied minor: +4 (§2L1.1(b)(4)).
• Weapons: +2 to +6, with floors of level 18 to 22 (§2L1.1(b)(5)).
• Substantial risk of death or serious injury: +2, with a floor of level 18. Examples in the commentary include carrying people in a trunk or engine compartment, overloading a vehicle, or leaving people in a dangerous remote area without enough water (§2L1.1(b)(6) and Application Note 3).
• Injury or death: +2 to +6 for injury, +10 for a death; a homicide guideline can apply instead (§2L1.1(b)(7), (c)).
• Holding people against their will or for payment: +2, with a floor of level 18 (§2L1.1(b)(8)).
• Role: the people being smuggled don't count as participants unless they helped smuggle others, and in large operations a leadership increase often applies (Application Note 6).

Document trafficking is sentenced under USSG §2L2.1 (base level 11, with increases for 6 or more documents), and getting or using a document for oneself under USSG §2L2.2 (base level 8, +2 for someone previously deported). The guidelines don't apply to a first illegal entry under § 1325(a), because it is a Class B misdemeanor; the judge can impose any sentence the statute allows (USSG §1B1.9).

Some districts also have early disposition ("fast-track") programs for these charges, which let the government ask for up to 4 levels off (USSG §3F1.1). For context only: the Sentencing Commission reports that smuggling made up about 17% of federal immigration cases in fiscal year 2025, the average sentence was 15 months, 64% of those sentenced were U.S. citizens, and 71% had little or no criminal history (USSC Quick Facts, FY 2025). Averages don't predict the sentence in any one case.

Pending at the Supreme Court. In Beaird v. United States, No. 25-5343, set for argument on October 13, 2026, the Court agreed to decide whether Stinson v. United States (1993) still states the rule for how much weight courts must give the Guidelines’ commentary, the notes that follow each guideline. The answer could affect rules on this page that come from commentary rather than from the guideline text itself.

Guideline numbers on this page are from the Guidelines Manual in effect since November 1, 2025, which no longer uses “departures”: the judge calculates the range, then weighs the factors in 18 U.S.C. § 3553(a). For more depth, see How the federal Sentencing Guidelines work, at Sentencing.net, a Criminal Center site.

How do these cases usually start and move?

Many smuggling cases start at a Border Patrol checkpoint or a traffic stop near the border, when agents find passengers who are not U.S. citizens. Others start with a tip about a "stash house," an employer investigation, or a document-fraud referral from immigration officials. Agents often interview the passengers right away, and their statements become key evidence.

The people who were smuggled may be held as "material witnesses" when their testimony is important and they might not be available later (18 U.S.C. § 3144). Their testimony is sometimes taken early by deposition, with the defense present, so they can be released. This can move the case quickly, and it is one reason the defense needs to get involved early.

Many smuggling and document cases are resolved by plea, sometimes through a fast-track program with a short deadline.

Immigration consequences, in general terms

For a non-citizen, a conviction for smuggling or document fraud can be an "aggravated felony" under immigration law (8 U.S.C. § 1101(a)(43)(N), (P)), which can lead to removal and limit future options. Defense lawyers must tell a non-citizen client whether a plea carries a risk of deportation (Padilla v. Kentucky, 559 U.S. 356 (2010)). Criminal Center handles the federal criminal case. For questions about status, relief from removal or visas, talk with an immigration lawyer.

The usual stages of a federal case

1. 1Investigation. Agents gather records and interview witnesses, often using grand jury subpoenas. Someone the prosecutor views as a "target" may get a target letter before an indictment (Justice Manual 9-11.151, 9-11.153).
2. 2Charges. A federal felony is usually charged by indictment: a grand jury decides in private whether there is probable cause (Fed. R. Crim. P. 6, 7). Some cases start with an arrest on a criminal complaint.
3. 3First appearance and detention. After an arrest, the person goes before a magistrate judge without unnecessary delay (Fed. R. Crim. P. 5). The judge decides whether they are released or held until trial (18 U.S.C. § 3142).
4. 4Evidence and motions. The government must turn over certain evidence (Fed. R. Crim. P. 16). The defense can ask the court to suppress evidence or dismiss charges (Fed. R. Crim. P. 12).
5. 5Plea or trial. Many federal cases end in a guilty plea, which the judge must find knowing and voluntary (Fed. R. Crim. P. 11). At trial, the government must prove every element beyond a reasonable doubt, and a jury verdict must be unanimous (Fed. R. Crim. P. 31(a)).
6. 6Sentencing. A probation officer writes a presentence report, and each side can object in writing within 14 days of receiving it (Fed. R. Crim. P. 32). The judge then decides the sentence under 18 U.S.C. § 3553(a).

What defense issues come up in these cases?

• Knowledge. Did the driver or host actually know, or recklessly ignore, that the passengers or tenants were here unlawfully? Giving a ride or renting a room is not a crime by itself.
• "In furtherance" and "harboring." Did the transport actually help the unlawful presence continue? Did the person conceal or shield someone, or just live with or employ them? Courts define these words in different ways.
• Encouraging after Hansen. Was there purposeful solicitation or help with a specific unlawful act, or only general speech?
• The stop. A roving Border Patrol stop needs reasonable suspicion (United States v. Brignoni-Ponce, 422 U.S. 873 (1975)); brief questioning at a fixed checkpoint does not (United States v. Martinez-Fuerte, 428 U.S. 543 (1976)). A search beyond that still needs a legal basis.
• Witness statements. Were the passengers' statements reliable, and did the defense get a fair chance to question them before they were released or removed?
• Profit and minimums. Was the offense really for profit, which can raise the maximum, trigger a § 1324(a)(2) minimum, and block the 3-level decrease?
• Counting. How many people were involved for the counts and for §2L1.1(b)(2)? Is the same group of people charged more than once?
• Risk and injury facts. Does the evidence actually support the danger, injury or detention increases?
• Documents. For § 1546, did the person know the document was fake or obtained by fraud, and was a false statement about a material fact?

Every case turns on its own facts. These are issues to look at, not predictions about how any case will turn out.

What happens after a conviction?

• Appeal. A notice of appeal is usually due within 14 days after the judgment is entered (Fed. R. App. P. 4(b)(1)(A)). Many plea agreements waive the right to appeal, but in Hunter v. United States (2026) the Supreme Court held that a waiver can’t be enforced when doing so would cause a miscarriage of justice, a high bar. See federal appeals at Sentencing.net.
• A § 2255 motion. A motion asking the sentencing court to vacate, set aside or correct the sentence, for example for ineffective assistance of counsel. It is usually due within one year after the conviction becomes final (28 U.S.C. § 2255(f)). See 2255motion.com.
• Compassionate release. A motion asking the judge to reduce a prison sentence for extraordinary and compelling reasons, filed after the person asks the warden and either exhausts BOP appeals or waits 30 days (18 U.S.C. § 3582(c)(1)(A)). It can’t be used to attack the validity of the conviction itself (Fernandez v. United States (2026)). See CompassionateRelease.com.
• Clemency. The President can pardon a federal offense or commute (shorten) a federal sentence (U.S. Const. art. II, § 2). See Clemency.com.
