Good Moral Character for Naturalization: What USCIS Checks on Your N-400

Part of Ellis Porter’s guide to U.S. citizenship through naturalization.

Before you file your N-400, read this

You have had your green card for years. You work, you pay your bills, and you are raising a family here. Then you open Form N-400 and see page after page of questions about arrests, taxes, child support, and voting. It is normal to worry that something from your past could cost you citizenship.

Good moral character is one of the core US citizenship requirements. It sits next to continuous residence, physical presence, English, and civics. This guide explains what the law says, how far back USCIS looks, and which problems are permanent. It also covers what changed in 2025 and 2026. The goal is simple: no surprises at your interview.

What does good moral character mean for naturalization?

Good moral character (GMC) means you have lived up to the standards of average citizens in your community. You must show this for a set period before you apply, and you must keep it up until you take the oath. You carry the burden of proof. The law does not define GMC directly. It lists conduct that rules it out.

The rule comes from INA 316(a). It says you must have "been and still is a person of good moral character" during the required period (8 U.S.C. 1427). The list of disqualifying conduct is in INA 101(f). The regulation, 8 CFR 316.10, tells USCIS to decide "on a case-by-case basis." It uses "the standards of the average citizen in the community of residence."

The standard of proof is a preponderance of the evidence. In plain terms, you must show it is more likely than not that you meet the requirement.

How far back does USCIS look? The GMC statutory period

For most people, USCIS looks at the 5 years before you file Form N-400. If you file as the spouse of a US citizen, the period is 3 years. Either way, it does not stop when you file. You must keep good moral character through the interview and up to the Oath of Allegiance.

The 3-year spouse route has its own conditions. Your spouse must have been a citizen the whole time, and you must have been living together in marital union. Our naturalization process guide walks through each route from filing to oath.

Can USCIS look at things older than 5 years?

Yes. Under 8 CFR 316.10(a)(2), USCIS can consider older conduct in two cases. One is when your recent conduct "does not reflect that there has been reform of character." The other is when the older acts are relevant to your present character. Some bars, covered below, apply no matter how long ago the conduct happened.

The GMC window usually lines up with the residence window, so your filing date matters for both. Our guide to continuous residence and physical presence explains how long trips abroad can reset that clock.

What permanently disqualifies good moral character?

A small group of acts bars you for life. Under 8 CFR 316.10(b)(1), you lack GMC if you were ever convicted of murder. The same is true if you were convicted of an aggravated felony on or after November 29, 1990. INA 101(f)(9) adds Nazi persecution, genocide, torture, extrajudicial killings, and severe violations of religious freedom.

"Aggravated felony" is an immigration term, and it is broader than it sounds. The USCIS Policy Manual chapter on permanent bars gives an example. Theft or a crime of violence counts when the court orders a prison term of one year or more, "even if the court suspended the entire sentence." The label on your court papers does not settle it. A lawyer needs to read the actual record.

What are the conditional bars to good moral character?

Conditional bars block good moral character only if the conduct happened during the statutory period. They come from INA 101(f) and are spelled out in 8 CFR 316.10(b)(2). Conduct outside the window is not an automatic bar, though USCIS may still weigh it.

Under 8 CFR 316.10(b)(2), you lack GMC if any of these happened during the period:

• You were convicted of a crime involving moral turpitude. A narrow exception covers certain minor offenses.
• You were convicted of two or more offenses with a combined sentence of 5 years or more.
• You violated a controlled substance law. The one exception is a single offense of simple possession of 30 grams or less of marijuana.
• You admit committing one of those crimes, even if you were never charged.
• You spent a total of 180 days or more in jail or prison because of a conviction.
• You gave false testimony under oath to get an immigration benefit.
• You were involved in prostitution or helped smuggle a person into the US.
• You practiced polygamy.
• You had two or more gambling convictions, or earned your income mainly from illegal gambling.
• You are or were a habitual drunkard.

A second group, in 8 CFR 316.10(b)(3), applies "unless the applicant establishes extenuating circumstances." It covers willfully failing to support your dependents and an affair that tended to destroy an existing marriage. It also covers other unlawful acts that reflect badly on your character. Separately, the USCIS Policy Manual says two or more DUI convictions in the period create a rebuttable presumption that you lack GMC.

Permanent vs conditional bars at a glance

The catch-all: officers can find you lack GMC for other reasons

Staying off the list is not enough. INA 101(f) ends with a catch-all. Falling outside every listed class "shall not preclude a finding that for other reasons such person is or was not of good moral character." That gives officers real discretion.

On August 15, 2025, USCIS issued Policy Memorandum PM-602-0188. It calls for a "holistic" review. It says judging GMC "involves more than a cursory mechanical review focused on the absence of wrongdoing." Officers must "account for an alien’s positive attributes and not simply the absence of misconduct."

The memo lists positive factors USCIS will stress:

• Community involvement and contributions in the US.
• Family caregiving, responsibility, and ties in the US.
• Education.
• Stable, lawful work history.
• Length of lawful residence in the US.
• Paying your taxes and meeting your financial duties.

The memo also targets acts "that, while technically lawful, may be inconsistent with civic responsibility." Its examples are "reckless or habitual traffic infractions" and "harassment or aggressive solicitation." On the positive side, it names signs of rehabilitation. These include catching up on child support, finishing probation, paying overdue taxes in full, and credible letters from your community.

Neighborhood investigations are back

On August 22, 2025, USCIS issued a memo resuming personal investigations under INA 335(a). On August 25, 2026, Policy Alert PA-2026-10 added this to the Policy Manual. USCIS may conduct "neighborhood investigations" or waive them. It will consider character letters you choose to provide, "preferably from U.S. citizens who are not family members."

Common issues to review before you file

Most people who worry about good moral character are not dealing with serious crime. They are dealing with everyday problems the N-400 asks about directly. Each one below is a reason to get advice before filing. None is a reason to give up.

DUIs

The USCIS Policy Manual says two or more DUI convictions during the period create "a rebuttable presumption" that you lack GMC. To overcome it, you need "substantial relevant and credible contrary evidence" that the convictions "were an aberration." Efforts to reform after the convictions do not, by themselves, prove GMC for the years of the convictions. A single DUI is not a listed bar, but it can still be weighed.

Unpaid taxes or unfiled returns

The USCIS Policy Manual chapter on conditional bars says a person who fails to file required returns or pay taxes "may be precluded from establishing GMC." It also recognizes "the complexities of filing taxes." You may still qualify if you fix the problem. A letter from the tax authority can show you filed and paid, or "made arrangements for payment" and are keeping up.

Child support

Willfully failing to support your children during the period blocks GMC unless you show extenuating circumstances. The Policy Manual says this applies "even if there is no court-ordered child support." If you are behind, expect to explain how long and why. Officers consider job loss, true inability to pay, and good-faith efforts to support your children.

Selective Service registration

Men generally must register with Selective Service between ages 18 and 26. The USCIS Policy Manual on attachment to the Constitution says USCIS will deny an applicant who knowingly and willfully failed to register during the period. It sorts applicants by age:

• Under 26: generally ineligible.
• Between 26 and 31: may be ineligible, but you get a chance to show the failure was not knowing or willful.
• Over 31: eligible.

Men who lived in the US from 18 to 26 only in lawful nonimmigrant status did not have to register.

False claims to US citizenship and voting

This area got much stricter. USCIS Policy Alert PA-2025-20, dated August 29, 2025, covers anyone who falsely claimed citizenship "for any purpose or benefit, including registering to vote." It also covers anyone who voted unlawfully. Unless a narrow exception applies, USCIS will issue a Notice to Appear, the document that starts removal proceedings. USCIS then generally denies the N-400.

A common trap is the DMV. The Policy Manual says answering "yes" to a citizenship question to register to vote can count as a false claim. That is true even if it happened while you applied for a driver’s license.

INA 101(f) has a narrow exception. It covers people whose parents are or were all US citizens, who lived here before age 16, and who reasonably believed they were citizens. If you think you may already be a citizen through a parent, read about the Certificate of Citizenship (Form N-600) first.

Arrests, probation, and expunged records

USCIS requires certified court records for arrests during the period, even arrests that did not end in a conviction. Under 8 CFR 316.10(c)(1), probation or parole is not an automatic bar. But USCIS will not approve your case until it is complete. An expunged record may still count as a conviction for immigration purposes, depending on why it was cleared.

Honesty on the form and at the interview

False testimony under oath to get an immigration benefit is a conditional bar. Under 8 CFR 316.10(b)(2)(vi), it applies "regardless of whether the information provided in the false testimony was material." Leaving out an old arrest because it seems minor can create a bigger problem than the arrest. When in doubt, disclose it and explain.

How can you show good moral character?

You show good moral character by answering every N-400 question truthfully, bringing certified records for anything in your past, and documenting the good parts of your life. Since the 2025 memo, positive evidence carries more weight than before.

Helpful evidence often includes:

1. IRS tax transcripts for the period, plus proof of any payment plan.
2. Proof of child support payments, if you owe support.
3. Certified court records for any arrest, citation, or charge.
4. Proof of Selective Service registration, or a status information letter.
5. Work and school records.
6. Letters from employers, community leaders, or neighbors.
7. Proof of volunteer work, caregiving, or community service.

None of this guarantees a result. It gives the officer the full picture, which is what current policy asks them to weigh.

Have your history reviewed before you file

Filing too early, or without explaining a problem in your past, can lead to a denial. In some cases, it can lead to removal proceedings. Sometimes waiting until an issue falls outside your period, fixing a tax problem first, or gathering the right records changes how your case looks.
