Good Moral Character for Naturalization: The Bars, the Catch-All, and the 2025 Guidance

It sounds subjective. It is not. Permanent and conditional bars, the conduct in between, and why the review belongs before you file.

By Lincoln Square Law · 8-minute read

Good moral character sounds like a soft, subjective standard. In naturalization it is neither. It is a statutory requirement with specific bars, a regulatory framework that reaches conduct inside and outside the statutory period, and, since August 2025, agency guidance directing officers to weigh the whole of an applicant’s life. It decides more naturalization cases than the civics test. This paper explains the structure of the requirement, the bars that end cases, the conduct that falls between the bars, and why an applicant’s history must be reviewed before an N-400 is filed.

The requirement and the period

An applicant must show that he or she has been a person of good moral character during the statutory period, generally the five years before filing (three years for spouses of citizens), and until the oath (INA 316(a)). The applicant bears the burden of proof. The officer is not limited to the statutory period. Conduct before it may be considered when it bears on the applicant’s present character, and some conduct is a bar no matter when it occurred (8 C.F.R. 316.10(a)(2)).

Permanent bars

Some conduct permanently prevents a finding of good moral character. The most important are:

• Murder. A conviction for murder at any time (8 C.F.R. 316.10(b)(1)(i)).
• Aggravated felonies. A conviction for an aggravated felony, as defined in the immigration statute, on or after November 29, 1990 (INA 101(f)(8)). The immigration definition includes offenses that state law may treat as misdemeanors, which is why the label on a state conviction is never the end of the analysis.
• Persecution and serious human rights violations, including participation in genocide, torture, or extrajudicial killings (INA 101(f)(9)).

Conditional bars within the period

Other conduct bars a finding of good moral character when it occurs during the statutory period (INA 101(f)). The list includes:

• Crimes involving moral turpitude and controlled substance offenses that would make a person inadmissible, with a limited exception for a single offense of simple possession of 30 grams or less of marijuana.
• Two or more offenses with aggregate sentences to confinement of five years or more.
• Confinement of 180 days or more in total as a result of convictions during the period.
• Drug trafficking, prostitution-related conduct, and smuggling of persons.
• Illegal gambling as a source of income, or two or more gambling convictions.
• Habitual drunkenness.
• Practicing polygamy.
• False testimony given for the purpose of obtaining an immigration benefit.

False testimony has a narrow meaning. The Supreme Court held that it covers oral statements made under oath with the subjective intent of obtaining an immigration benefit, and does not include misrepresentations in documents or statements made for other reasons (Kungys v. United States, 485 U.S. 759 (1988)). Written misrepresentations can still create serious problems under other provisions.

The catch-all and the regulations

The statute provides that the listed bars are not exclusive, and that an officer may find an applicant lacks good moral character for other reasons. The regulations identify additional conduct that, absent extenuating circumstances, supports a finding against the applicant, including willful failure to support dependents, extramarital affairs that tended to destroy an existing marriage, and unlawful acts that adversely reflect on moral character even without a conviction (8 C.F.R. 316.10(b)(3)).

In practice, the catch-all is where many cases are decided: unpaid taxes or failure to file, unpaid court-ordered child support, repeated or serious traffic offenses such as driving under the influence, probation violations, and false claims to U.S. citizenship or unlawful voting. False claims to citizenship and unlawful voting also carry separate inadmissibility and deportability consequences (INA 212(a)(6)(C)(ii), 212(a)(10)(D), 237(a)(3)(D), and 237(a)(6)).

The August 2025 guidance

In an August 15, 2025 memorandum, USCIS directed officers to evaluate good moral character through the totality of the circumstances. The guidance emphasizes that officers should weigh positive attributes, including community involvement, family caregiving and ties, education, stable employment, length of lawful residence, and compliance with tax and financial obligations. It also describes conduct that may weigh against an applicant even if it falls short of a statutory bar, and the kinds of evidence of rehabilitation officers may consider, such as completed probation, payment of overdue taxes or support, and testimony from the community.

For applicants, the guidance means two things. First, positive evidence matters and should be submitted deliberately. Second, conduct that might once have been overlooked may now be weighed, so it should be addressed rather than hoped away.

Convictions, dispositions, and state relief

Immigration law applies its own definition of a conviction (INA 101(a)(48)(A)). Many state dispositions that avoid a conviction under state law, including some forms of supervision or deferred adjudication, can still be convictions for immigration purposes, and an expungement or sealing generally does not erase a conviction for immigration purposes. A state decriminalization or legalization, including state cannabis laws, does not change federal immigration consequences for conduct involving a federally controlled substance. Every applicant with any arrest or charge should obtain certified dispositions and have them analyzed under immigration law before filing.

Waiting out a conditional bar

Because most bars apply only when the conduct occurs within the statutory period, timing can matter. An applicant whose last disqualifying conduct occurred four years ago may be eligible after the full five-year period has passed, measured back from the filing date. Waiting does not cure a permanent bar, and it does not erase conduct the officer may still weigh under the catch-all or the totality-of-the-circumstances review. But for conditional bars, a later filing date is sometimes the most effective legal strategy. The calculation depends on the dates of the conduct, the conviction, and any confinement, not only the date of arrest, so each date should be confirmed from court records.

Taxes and support, in more detail

Tax problems are among the most common reasons for delay and denial, and among the most fixable. An applicant who failed to file required returns should file them. An applicant who owes taxes should enter into an installment agreement with the IRS or the state and make the payments before the interview. Officers generally look for evidence that the applicant has taken responsibility, not perfection. The same is true of child support: arrears that are being paid under a court order, with proof of current payments, present very differently from arrears that are being ignored. For both, documents from the agency, not the applicant’s own summary, are the evidence officers expect.

The risk that outranks denial

A naturalization application requires the applicant to disclose his or her entire history under penalty of perjury, and the officer reviews it against government records. For some applicants, the review reveals not just a reason to deny naturalization but a basis for removal: an offense that made the applicant deportable, a problem with how permanent residence was obtained, or a false claim to citizenship. An applicant in that position may be better served by not filing, by waiting until a bar period has passed, or by addressing the problem first. That decision should be made with counsel, before the N-400 is filed.

Building the good moral character record

• Certified dispositions for every arrest, citation, or charge, anywhere and at any time.
• Tax transcripts for the statutory period and proof of any payment plan.
• Child support records showing payments are current.
• Selective Service registration or a status information letter.
• Positive evidence: employer letters, community and volunteer records, education, caregiving responsibilities.
• Rehabilitation evidence where relevant: completed probation, treatment programs, paid fines and restitution.

Analyze good moral character before filing

Good moral character is a structured legal requirement: permanent bars, conditional bars within the statutory period, a catch-all that captures much ordinary misconduct, and, since 2025, a totality-of-the-circumstances review that weighs positive evidence as well. Because the naturalization application exposes the applicant’s full history, the analysis belongs before filing, with certified records in hand.
