The Immigration and Nationality Act (INA) requires naturalization applicants to prove 'good moral character' (GMC) for the statutory period (typically 5 years, or 3 years for marriage cases).

But what does GMC actually mean? Unlike physical presence (which is a simple day count), moral character is subjective.

This article explains what USCIS looks for, what disqualifies you, and how to document your GMC.

The Legal Definition of Good Moral Character

Unfortunately, the INA does not define GMC positively. Instead, it lists actions that automatically bar a finding of GMC.

Everything else is left to the discretion of the USCIS officer.

Core principle: 'Good moral character' means conduct that measures up to the standards of average citizens in the community where the applicant lives.

Permanent bars to GMC (with no time limit) include:

  • Conviction of murder at any time.
  • Aggravated felony conviction (defined by INA §101(a)(43)) — includes drug trafficking, money laundering over $10k, rape, child abuse, etc.
  • Participation in Nazi persecution or genocide.
  • False claim to U.S. citizenship to obtain a benefit.

Conditional Bars (Statutory Period Only)

These offenses block GMC only if they occurred during the 5-year (or 3-year) statutory period.

After the period ends, you may become eligible again.

  • Crimes involving moral turpitude (CIMT): Theft, fraud, assault with intent to harm, prostitution. One CIMT is a bar unless it was a petty offense (sentence ≤ 6 months, actual jail ≤ 30 days).
  • Controlled substance violations: Any drug crime (except simple possession of 30g or less of marijuana — but note: federal law still considers marijuana illegal).
  • Two or more convictions with total sentence ≥ 5 years: Even if the crimes were non-CIMT.
  • False testimony under oath: If given to obtain an immigration benefit.
  • Prostitution or commercialized vice: Within the statutory period.
  • Habitual drunkenness or gambling: Vague, but USCIS may request evidence (medical records, bankruptcy from gambling).
  • Unlawful voting: Claiming the right to vote as a non-citizen.
Important: Even minor offenses can be disqualifying. A single DUI is generally not a bar unless accompanied by aggravating factors (injury, child in car, multiple DUIs). But three DUIs within 5 years will likely result in denial.

What Evidence Can You Submit to Prove GMC?

Since GMC is a positive assertion, you must submit documents showing you are a law-abiding, responsible person.

Required Disclosures (Even Without Conviction)

  • All arrests, citations, or charges: Even if dismissed or expunged. Failure to disclose is fraud (permanent bar).
  • Court dispositions (certified copies): For every arrest or conviction, showing the final outcome (dismissed, probation, jail).
  • Probation or parole records: If you completed community supervision.
  • Child support payments: Proof you are current (or never had an obligation).
  • Tax compliance letter (IRS Tax Transcript): Proves you filed all required returns. Failure to file is a GMC issue.

Affirmative Character Evidence (Optional but Helpful)

  • Letters of recommendation: From employers, clergy, community leaders, neighbors. They should state how long they've known you and attest to your honesty, work ethic, and civic involvement.
  • Volunteer records: Food bank, school PTA, animal shelter — shows community contribution.
  • Proof of stable employment: W-2s, pay stubs, promotion letters.
  • Proof of family support: Marriage, birth certificates, shared finances.
  • Criminal background check (state or local police): Even though USCIS will run FBI checks, providing your own shows transparency.

What About Expunged or Juvenile Records?

USCIS ignores state expungements. Under federal immigration law, an expunged conviction still counts as a conviction for GMC purposes.

Juvenile adjudications are generally not counted unless you were tried as an adult.

Pro tip: If you have any criminal record — even a sealed or expunged minor offense — consult an immigration attorney before filing N-400. Some offenses require filing a waiver (Form I-601) or waiting additional years (7 years for multiple CIMTs).

The 'Rehabilitation' Factor

Even if you committed a disqualifying act, USCIS may still approve if you show rehabilitation — but this is rare.

Evidence includes completion of drug treatment, AA meetings, no further arrests for 5+ years, and community service.

Consult a lawyer before attempting this.

In summary, honesty is critical. Disclose every arrest, no matter how minor.

Provide court-certified dispositions for each. Then supplement with positive character letters and proof of stable life.

An incomplete application is often worse than a denied one.
