Good Moral Character on the N-400: A Practical Checklist

What Good Moral Character means for naturalization

Good Moral Character (GMC) is one of five statutory requirements for naturalization under INA § 316(a) (8 U.S.C. § 1427(a)). USCIS must find that the N-400 applicant has been a person of good moral character throughout the statutory lookback period and up to the date of the oath of allegiance. The other requirements are continuous residence, physical presence, English and civics knowledge, and attachment to the principles of the Constitution.

INA § 101(f) (8 U.S.C. § 1101(f)) defines GMC by listing categories of conduct that bar a finding of good moral character. The categories fall into two groups: permanent bars and conditional (within-lookback) bars. Anything not enumerated is left to USCIS discretion, evaluated against the totality of the applicant's conduct.

The lookback period

• Five years for most applicants under INA § 316.
• Three years for spouses of U.S. citizens naturalizing under INA § 319(a) (8 U.S.C. § 1430(a)), provided the marriage has been intact and the U.S. spouse has been a citizen for the full three years.
• One year for VAWA self-petitioners under INA § 319(a).
• One year for active-duty military applicants under INA § 328 (8 U.S.C. § 1439).
• No lookback for certain wartime military applicants under INA § 329 (8 U.S.C. § 1440); the entire life is reviewed.

USCIS may extend its review past the statutory period and consider earlier conduct as part of the discretionary GMC analysis, but cannot use earlier conduct to find an automatic statutory bar (with the exception of permanent bars).

Permanent bars under INA § 101(f)

The following conduct permanently bars GMC regardless of when it occurred:

• Murder.
• Aggravated felony conviction on or after November 29, 1990 (defined at INA § 101(a)(43)).
• Nazi persecution, genocide, torture, or extrajudicial killing (the broader human-rights bars under INA § 212(a)(3)(E)).

A permanent bar ends naturalization eligibility entirely. The only remaining options are to seek pardon, vacatur of the conviction under appropriate state procedures, or to remain a lawful permanent resident.

Conditional bars within the lookback period

INA § 101(f) lists conduct that bars GMC if it occurred during the statutory lookback:

• One or more crimes of moral turpitude (subject to the petty-offense exception in INA § 212(a)(2)(A)(ii)).
• Two or more offenses of any kind with aggregate sentences of five years or more.
• A controlled substance violation (other than a single offense of simple possession of 30 grams or less of marijuana).
• Confinement to a penal institution for 180 days or more as a result of conviction.
• Habitual drunkard.
• Income from illegal gambling or two or more gambling convictions.
• Prostitution-related conduct under INA § 212(a)(2)(D).
• Smuggling another person for entry under INA § 212(a)(6)(E).
• Polygamy.
• False testimony under oath given for the purpose of obtaining any immigration benefit during the lookback.

Each of these can be argued, mitigated, or distinguished — but they trigger statutory bars during the lookback and the burden shifts hard to the applicant.

Discretionary GMC factors under 8 C.F.R. § 316.10

If no statutory bar applies, USCIS evaluates the totality of conduct during the lookback. The regulation directs adjudicators to weigh:

• Compliance with tax laws — filing returns on time, payment of taxes owed.
• Compliance with child support obligations — court-ordered support, willful failure to pay.
• Selective Service registration for male applicants who were 18 to 25 during the relevant period.
• Traffic offenses — pattern, frequency, severity (DUI especially weighty).
• Civil judgments and bankruptcies suggesting fraud or evasion.
• False statements on USCIS applications.
• Any criminal conduct that did not result in conviction — arrests, dismissals, deferred adjudications.
• Probation or parole status during the lookback (eligibility frequently delayed until probation ends).

USCIS officers also assess the applicant's testimony at interview, including demeanor, candor, and willingness to take responsibility for past conduct.

Critical tax issues

Tax non-compliance is the most common GMC issue our attorneys encounter on N-400s. Before filing:

• Confirm all federal and state returns for the lookback period are filed.
• If taxes are owed, set up an IRS payment plan and bring proof of the plan and current payments to the interview.
• If returns were filed late or amended, gather the transcripts and a brief explanation.
• If the applicant did not file because income was below the threshold, prepare a written explanation citing the IRS filing threshold for the relevant year.

A pending IRS payment plan that the applicant honors generally satisfies GMC; an unaddressed tax debt does not.

Critical Selective Service issues

Men ages 18 to 25 must register for Selective Service. Failure to register before age 26 is a GMC concern only if the failure was knowing and willful. Applicants 26 to 31 should request a Selective Service Status Information Letter at sss.gov and bring the letter to the interview. Applicants over 31 are generally past the GMC concern because the lookback no longer reaches the failure to register.

What to bring to the N-400 interview

• The complete N-400 with all updates.
• Certified court dispositions for every arrest or charge during the lookback (even dismissals).
• IRS tax transcripts for the lookback years.
• Proof of payment plans or compliance with court orders (child support, restitution, probation completion).
• Selective Service Status Information Letter if applicable.
• Documentation of any positive equities — community service, employment, family responsibilities, military service.

Common pitfalls

• Failing to disclose an arrest because the case was dismissed. USCIS will see it. Disclose with a certified disposition.
• Treating a pre-trial diversion as "not a conviction" without checking. Many state diversions are still convictions under federal immigration definitions per Matter of Roldan-Santoyo, 22 I&N Dec. 512 (BIA 1999), as modified by Lopez v. Gonzales, 549 U.S. 47 (2006), and Pereida v. Wilkinson, 592 U.S. 1 (2021).
• Filing during probation. USCIS typically denies or holds the case until probation is complete.
• Ignoring a DUI. Even a first DUI is a weighty discretionary factor; USCIS may delay or deny if there is a pattern.
• Forgetting a foreign criminal record. USCIS requests police certificates from every country of residence; undisclosed foreign convictions surface and produce denials for lack of candor as well as for the underlying conduct.

What to do this month

Audit your last five years (or three, for spouses) honestly. Pull tax transcripts. Order certified dispositions for any arrest. Address open issues — finish probation, set up tax payment plans, request Selective Service letters — before filing the N-400.
