Green Card Granted in Error? Why Applying for Citizenship Can Put Your Residency at Risk

Last reviewed: September 2026

Elena is a composite, not a real client. She adjusted her status in Aurora, Colorado through a family petition fourteen years ago, using a neighborhood preparer. Her U.S. citizen children want her to file Form N-400. She also remembers a shoplifting arrest from her twenties that was dismissed. A coworker's husband filed his N-400 last year and ended up in immigration court instead of at a swearing-in ceremony.

Filing Form N-400 reopens the entire immigration file USCIS holds on an applicant, back to the original grant of permanent residence. If that grant had a problem, whether an undisclosed arrest, a preparer's mistake, or an error inside USCIS itself, naturalization is often when it surfaces.

Nobody should file an N-400 after years of residence without first checking that the original green card holds up.

The Rule Behind a Green Card Granted in Error: "Lawfully Admitted"

What INA § 318 requires, in plain English

Federal law does not let USCIS approve a Form N-400 unless the applicant has been "lawfully admitted to the United States for permanent residence." That phrase comes from INA § 318, codified at 8 U.S.C. § 1429, which also bars naturalization while a removal proceeding is pending against the applicant. A green card by itself does not prove lawful admission.

The definition sits in INA § 101(a)(20), 8 U.S.C. § 1101(a)(20): the status of having been lawfully accorded the privilege of residing permanently in the United States as an immigrant, in accordance with the immigration laws, that status not having changed. The phrase "in accordance with the immigration laws" is where the risk lives.

Why a green card in your wallet isn't the same as a lawful admission

The USCIS Policy Manual, Volume 12, Part D, Chapter 2, is blunt: "a Permanent Resident Card alone is insufficient to establish that the applicant has been lawfully admitted for permanent residence in accordance with all applicable provisions of the INA." Under 8 CFR § 316.2(b), an N-400 applicant must prove, by a preponderance of the evidence, that they were lawfully admitted for permanent residence. USCIS looks at the original grant of permanent residence to decide that question, which is exactly where a green card granted in error breaks down.

In Matter of Koloamatangi, 23 I&N Dec. 548 (BIA 2003), the Board of Immigration Appeals held that a person who obtained permanent residence through fraud or misrepresentation was never lawfully admitted, because "lawfully" requires compliance with the substantive legal requirements, not just an approval. The Board wrote that such a person is "deemed, ab initio, never to have obtained lawful permanent resident status once his original ineligibility therefor is determined." Federal appeals courts continue to rely on that reasoning.

"But I didn't do anything wrong." Why agency and preparer mistakes still count

Per USCIS Policy Manual guidance, "the applicant is generally ineligible for naturalization under such circumstances, even if he or she did not commit any fraud in obtaining the immigrant visa, admission to the United States, or LPR status." The federal appeals court covering Washington reached the same conclusion in a case with no fraud and no agency knowledge of the problem at the time. The appeals court covering Colorado has not decided the question, so immigration judges there follow the Board's rule.

Feeling blameless and being eligible are different things.

How a Green Card Gets Granted in Error

A conviction or arrest that wasn't disclosed, or wasn't understood

One common trigger is criminal history that was left off the original green card paperwork, or that the applicant did not realize mattered. Whether an old case made someone ineligible when the green card was approved depends on what the conviction was, the sentence, and whether an exception or waiver applied at the time. An arrest that ended without a conviction generally does not make someone ineligible by itself, with exceptions such as suspected drug trafficking or admitted drug-related conduct, though leaving it off the forms can raise a separate misrepresentation question. Form N-400 asks whether the applicant has ever been arrested, cited, charged, or detained, and its instructions call for disclosure even of records that were sealed, expunged, or dismissed. That puts old cases back in front of USCIS even if nothing has happened since the green card was approved.

Some older Colorado misdemeanor sentences carry a separate federal risk. For certain offense types, such as theft, a sentence of a year or more, even if suspended, can make the conviction an "aggravated felony" under federal immigration law. An aggravated felony conviction entered on or after November 29, 1990 permanently bars the good moral character finding naturalization requires, and one entered after admission makes a permanent resident deportable. Colorado capped most misdemeanor jail sentences at 364 days in 2022, so the risk mostly affects older cases, which our aggravated felony guide covers.

Colorado deferred judgments, dismissed cases and sealed records: why "it went away" may not mean it's gone for immigration

A Colorado deferred judgment under C.R.S. § 18-1.3-102 starts with a guilty plea. If the person completes the court's conditions, the plea is withdrawn and the case is dismissed, and Colorado law treats it as if no conviction was entered. Federal immigration law uses its own definition. Under INA § 101(a)(48)(A), a formal judgment of guilt is a conviction. So is a guilty or no-contest plea, or an admission of enough facts to support a finding of guilt, when the judge also orders some form of punishment, penalty, or restraint on liberty, such as supervision or probation-style conditions. The Board of Immigration Appeals has held that a state deferred-adjudication procedure meeting that definition is a conviction, and that a later dismissal or expungement under a state rehabilitative law does not undo it. The federal appeals court covering Colorado has applied the same definition to a neighboring state's deferred sentence and found a conviction, though it has not addressed Colorado's procedure by name in a published decision. A case dismissed without any plea or admission, or a diversion agreement that required neither, generally does not meet this definition, though some agreements include admissions that change the analysis.

Sealing a Colorado record limits who can see it. It does not change how federal immigration law treats the plea or admission underneath it, and federal fingerprint records may still show the arrest. A conviction vacated because of a legal defect in the original case, such as a plea entered without accurate advice about immigration consequences, is analyzed differently from one dismissed or sealed after the person completed its terms. In immigration cases heard in the Ninth Circuit, which includes Washington, an older rule treating certain expunged first-offense drug possession convictions as erased still applies, but only to convictions entered before July 14, 2011. Immigration courts in Colorado do not apply it. Our guide on crimes of moral turpitude explains how deferred judgments can still count as immigration convictions.

Misrepresentation, including mistakes a notario or preparer made on your forms

A false or missing answer on the original green card forms can defeat lawful admission when it hid a real eligibility problem, whether the applicant, a notario, or an unlicensed preparer wrote it. Applicants sign those forms under penalty of perjury. Whether a preparer's error also counts as the applicant's own fraud is a separate, fact-specific question.

Agency error and the wrong-category approval

Sometimes the mistake belongs to USCIS, which can approve a case in the wrong category or approve an adjustment the applicant was not actually eligible for at the time. USCIS policy, and the federal appeals courts that have ruled on it, generally treat the result the same way: a person approved when not eligible was not lawfully admitted, even when the mistake was the agency's.

Warning Signs to Raise Before You File

Each item below is a reason to get a review before filing, not a verdict.

• Any arrest or charge anywhere, even if it was dismissed, deferred, sealed, or expunged
• Someone else filled out your original green card forms, especially a notario or unlicensed preparer
• You are not sure what your I-485 or original visa application actually said
• A prior removal order, an unlawful entry, or a visa problem before your green card was approved
• An approval that came unusually fast, or through a category you do not fully understand
• A marriage-based case where the marriage ended within the first few years

What USCIS Can Do Once the N-400 Reopens Your File

N-400 denial for failure to show lawful admission

If an examining officer concludes an applicant cannot meet the burden under 8 CFR § 316.2(b), USCIS denies the N-400.

A Notice to Appear and removal proceedings

When USCIS concludes an applicant was never lawfully admitted, DHS can also issue a Notice to Appear, which starts removal proceedings in immigration court. Whether it does depends on the facts and on USCIS's current NTA guidance, which has changed from one administration to the next. Effective November 18, 2020, where a removal proceeding is already pending against an applicant, USCIS denies the N-400 under INA § 318 based solely on the pending proceeding. Filing citizenship paperwork can move a quiet, unresolved eligibility question into an active removal case.

Rescission under INA § 246, and the five-year question

USCIS can also formally rescind permanent residence obtained through adjustment of status under INA § 246, 8 U.S.C. § 1256, if it appears within five years of the adjustment that the person was not eligible. That clock limits rescission itself and does not protect a long-time green card holder from removal proceedings built on the same defect.

Most federal appeals courts that have decided the question, including the one covering Washington, have held that the five-year limit applies only to formal rescission, not to removal. Only one federal appeals court, covering neither Colorado nor Washington, has held otherwise, and only for people who adjusted status inside the United States. No federal appeals court covering Colorado has decided this question directly. Immigration judges in Denver are bound by the Board of Immigration Appeals' position, which treats the five-year limit as a restriction on rescission alone.

For Colorado and Washington residents, the five-year limit is not a safe harbor against removal under current law.

Why "Just File and See" Is the Dangerous Path

The N-400 is a sworn application that invites a full review

Form N-400 is signed under penalty of perjury and asks for a complete history, not an update since the green card was approved. Leaving an arrest off the N-400 can create a good moral character problem of its own, separate from whatever the original record shows.

What a pre-filing review looks like

An immigration attorney's pre-filing review starts with the A-file, requested through the FOIA process, then works through criminal records and the original I-485 or visa forms, compared line by line against what happened.

Timing: why a review before filing keeps options open that disappear after an NTA

Filing first and hoping the review catches nothing is the wrong order. Before filing, an applicant has room to wait, correct a record, or pursue other options. Once a Notice to Appear issues, some of that room closes. The file should be reviewed before the government sees an application.

Your Options if a Problem Turns Up

Choosing not to file (yet)

For some clients, the right move after a review is to hold the N-400 and address whatever the review found first, which often preserves the most choices.

Waivers and relief that may be available, depending on the facts

Depending on the facts, relief can include fraud or misrepresentation waivers, re-adjustment of status, or other relief in immigration court, and none apply automatically. One caveat: someone found never to have been lawfully admitted generally cannot use cancellation of removal for permanent residents, because that relief requires at least five years as a lawfully admitted permanent resident, the exact fact in question.

Building a defense if you're already in proceedings

Someone already served with a Notice to Appear may still have options, depending on the record, though some paths narrow once proceedings start. Immigration court defense draws on the same relief categories and the record in the file.
