No. Being undocumented in California, meaning present in the United States without legal immigration status, such as after a visa overstay, is a civil immigration matter rather than a crime by itself. Separate federal crimes cover improper entry, illegal reentry after a removal order, and willfully failing or refusing to register, each under its own statute.

Is unlawful presence by itself a federal crime?

No. Unlawful presence, meaning time in the United States without admission or parole, or after an authorized stay expires, can affect future immigration applications, but it is not a crime.

USCIS describes unlawful presence this way: it is "any period of time when you are present in the United States without being admitted or paroled, or when you are present in the United States after your 'period of stay authorized by the Secretary' expires." Depending on how much unlawful presence a person accrues, and whether the person leaves and tries to return, it can trigger a bar to admission of three years, ten years, or longer under 8 U.S.C. 1182(a)(9)(B) and (a)(9)(C). Some people facing these bars may qualify for a waiver of inadmissibility. These bars are decided by immigration authorities, such as an immigration judge, USCIS, or a State Department consular officer, not by a criminal court.

Immigration and Customs Enforcement treats this as a civil status enforced with civil tools. ICE's own guidance says officers "briefly detain aliens when they have reasonable suspicion that the aliens are illegally present in the United States," and may arrest a person using a Form I-200 civil administrative warrant, which does not require a judge's signature; a Form I-205 warrant, by contrast, authorizes removal only after an immigration judge has already issued a final order.

Registration is a separate, narrower duty. Under 8 U.S.C. 1302(a), a noncitizen age 14 or older who stays 30 days or longer must apply for registration and fingerprinting unless already registered, for example through a visa application. USCIS's current registration guidance lists who still needs to register, including "aliens present in the United States without inspection and admission or inspection and parole who have not otherwise registered (that is, aliens who crossed the border illegally)." Willfully failing to apply is a separate misdemeanor under 8 U.S.C. 1306(a), punishable by up to six months in custody.

What federal crime applies to crossing the border without authorization?

Entering or attempting to enter the United States at an improper time or place, or evading inspection, is a separate federal crime called improper entry.

Entering or attempting to enter the United States at a time or place other than one designated by immigration officers, eluding inspection, or entering through a willfully false or misleading statement or the willful concealment of a material fact, is a federal crime under 8 U.S.C. 1325(a), titled "Improper entry by alien." A first offense carries a fine or up to six months in custody, or both; a later offense carries a fine or up to two years, or both. Under the general federal classification rule, 18 U.S.C. 3559(a), a maximum of six months is a Class B misdemeanor, and a maximum of two years is a felony. Section 1325(b) adds a civil penalty for each entry or attempted entry when the person is apprehended while entering at an improper time or place: $100 to $500 under the inflation adjustment in 8 C.F.R. 280.53, and the statute doubles it for someone already penalized under that subsection. It applies on top of, not instead of, any criminal penalty. The firm's answer on federal penalties for harboring or transporting an undocumented person covers a related but different crime, helping someone else enter or stay, rather than entering oneself.

Entry-related federal crimes and their maximum penalties.

Statute Covers Maximum penalty
8 U.S.C. 1325(a), first offense Improper entry or evading inspection Fine or 6 months, or both
8 U.S.C. 1325(a), later offense Same conduct, repeated Fine or 2 years, or both
8 U.S.C. 1326(a) Reentry after removal, no advance consent Fine or 2 years, or both
8 U.S.C. 1326(b)(1), (2) Reentry after removal, with certain priors Up to 10 or 20 years

Is reentering the country after being removed a federal felony?

Yes, unless the government gave advance consent to reapply. The base offense already exceeds the one-year line that separates a misdemeanor from a felony under federal law.

Under 8 U.S.C. 1326(a), a person who was denied admission, excluded, deported, or removed, and who then enters, attempts to enter, or is found in the United States without the Attorney General's advance consent to reapply, can be fined or imprisoned for not more than two years, or both. That two-year maximum already makes a base charge a federal felony under 18 U.S.C. 3559(a). Sections 1326(b)(1) and (b)(2) raise the exposure further when the earlier removal followed three or more qualifying misdemeanors or a felony: up to 10 years for those prior convictions, other than an aggravated felony, and up to 20 years when the prior conviction was an aggravated felony. Whether any of this applies to a specific case depends on that person's exact removal and conviction history, which a record check can confirm.

Can a criminal conviction make an undocumented person's situation worse?

Separate from the entry crimes above, certain convictions can make someone removable or block future relief, a collateral consequence layered on top of whatever a criminal court decides.

When an old conviction is the problem, post-conviction relief can sometimes undo it, such as a motion to vacate under Penal Code 1473.7 by a person no longer in criminal custody, when "prejudicial error" damaged their ability to meaningfully understand, defend against, or knowingly accept the conviction's immigration consequences. USCIS's own Policy Manual draws a sharp line here: a judgment vacated for a constitutional defect, a statutory defect, or a pre-conviction error affecting guilt is not a conviction for immigration purposes, but one dismissed for any other reason, "such as completion of a rehabilitative period (rather than on its merits) or to avoid adverse immigration consequences," still counts as a conviction. The firm's answer on how California record relief affects an immigration case covers that distinction in more depth. Getting an immigration review before any plea, not after, is the way to raise an immigration concern while it can still change the outcome.

Yes, in some cases, depending on the person's history. Immigration proceedings offer several paths that do not require legal status to begin with.

A person placed in removal proceedings is not automatically without options. For someone without a green card, cancellation of removal under 8 U.S.C. 1229b(b)(1) is one path an immigration judge can consider. It requires at least 10 years of continuous physical presence, good moral character during that time, and no conviction for certain listed offenses. The person must also show that removal would cause exceptional and extremely unusual hardship to a spouse, parent or child who is a U.S. citizen or permanent resident. It is discretionary relief, not a guaranteed outcome. Other paths, such as asylum or a visa for a victim of certain crimes or of trafficking, carry their own eligibility rules, and how the person entered can still matter: a U visa applicant who entered without inspection, for example, may need a waiver of inadmissibility on Form I-192.

Frequently asked questions

Is overstaying a visa a felony or a misdemeanor?

Neither. Overstaying a visa is not, by itself, a federal crime. It is unlawful presence, a civil ground under 8 U.S.C. 1182(a)(9)(B) that can affect future admissibility; USCIS still treats a person admitted with a visa as registered even after the visa expires.

What is the difference between unlawful presence and illegal entry?

Unlawful presence is a status: time in the country without authorization or after an authorized stay expires. Illegal entry is an act, crossing at an improper time or place or evading inspection, which 8 U.S.C. 1325 makes a separate federal crime.

Can ICE arrest someone without a judge's warrant?

For civil immigration enforcement, yes. ICE officers can issue and carry out Form I-200 civil administrative arrest warrants on their own authority; a Form I-205 warrant instead authorizes removing someone who already has a final order of removal.

Does a civil immigration finding create a criminal record?

No. A civil finding of inadmissibility or removability, made by immigration authorities, does not by itself create a criminal conviction. A criminal record comes from a criminal arrest or prosecution, such as for improper entry or illegal reentry, and it can list arrests and charges as well as convictions.

Is illegal reentry always prosecuted as a felony?

The base offense under 8 U.S.C. 1326(a) carries up to two years, which federal classification rules treat as a felony. Whether a specific case is actually charged, and at what level, depends on the person's history and the prosecutor's decision.

Does failing to register carry a specific fine?

Yes. Willfully failing or refusing to register when required is a misdemeanor under 8 U.S.C. 1306(a), with a fine, up to six months in custody, or both. The statute lists a $1,000 fine, but the general federal fine law, 18 U.S.C. 3571(b)(6), sets $5,000 as the limit for this class of misdemeanor, the figure USCIS gives.
