Good Moral Character for Naturalization

To naturalize, you must show good moral character (GMC) for the 5 years before you file Form N-400, or 3 years under the spouse rule, and all the way to your oath. Some acts bar you permanently, others bar you only if they happened within that period, and the officer can also weigh conduct from before it. Since August 2025, USCIS guidance tells officers to look at the whole person, including positive contributions as well as negative conduct.

The statutory period

The period counts back from your filing date:

GMC must also continue after filing, through the interview and until the oath. An arrest after the interview but before the ceremony must be reported on the Form N-445 questionnaire and can stop your oath.

Permanent bars

Some acts make you permanently unable to show GMC, no matter when they happened. Key examples:

If any of these may apply to you, speak with an immigration attorney before filing.

Conditional bars within the statutory period

These acts bar GMC if they happened during the 5-year (or 3-year) period. Common examples:

Note that federal law treats marijuana as a controlled substance even where state law allows it. Working in or using legal cannabis can still be a problem for naturalization.

The "catch-all": other unlawful acts

Even if no listed bar applies, an officer can find a lack of GMC based on unlawful acts during the period that adversely reflect on your character, unless there are extenuating circumstances. Examples include tax evasion, insurance fraud, or a pattern of DUIs.

The 2025 holistic standard

A USCIS policy memo dated August 15, 2025 restores a totality of the circumstances approach. Officers are told to look beyond the absence of crimes and consider:

Positive factors, such as:

Negative factors, such as:

Evidence of rehabilitation for past misconduct, such as completed probation, paid fines and restitution, treatment programs, and letters from employers or community members.

Since August 25, 2026, USCIS also generally conducts neighborhood investigations, unless waived. Applicants may voluntarily submit character reference letters, preferably from U.S. citizens who are not family members. USCIS considers those letters when deciding whether to waive the investigation.

Voting and false citizenship claims

Registering to vote or voting in an election where only citizens may vote, as a non-citizen, is one of the most serious problems on an N-400. It can make you ineligible, and it can also have criminal and removal consequences. The same goes for falsely checking "U.S. citizen" on a job form (I-9) or a loan application. If any of this happened, even by mistake at a DMV, talk to a lawyer before you file.

Taxes

USCIS asks whether you owe overdue taxes and whether you've ever filed as a "nonresident." If you owe taxes:

Unpaid taxes without a plan, or failing to file returns, can count against GMC.

Disclose everything

The N-400 asks about arrests, citations and charges even if they were dismissed, sealed or expunged, and even if they happened as a juvenile or abroad. Officers have your FBI record. Not disclosing something can be treated as false testimony, which is itself a bar to GMC, often more serious than the original offense.

For every incident, bring certified court dispositions and police reports to the interview. Our list of documents to bring to the interview covers what's needed.

When to get legal help

Talk to an immigration attorney or a DOJ-accredited representative before filing if you have:

A denial for GMC can also lead to referral to immigration court in some cases, so the stakes are higher than just the fee. If you're denied, see N-400 denied: what to do. This article is general information, not legal advice.

Frequently asked questions

Does a DUI make me ineligible?

A single DUI doesn't automatically bar GMC, but USCIS examines it closely, especially if recent. Multiple DUIs within the period can lead to a finding that you lack good moral character. Bring all court records and proof of completed sentences.

Do I need to report traffic tickets?

The N-400 asks about citations. Minor traffic tickets usually don't affect GMC, but you should still disclose them if the form asks and bring proof that fines were paid. Tickets involving alcohol, drugs or arrests need court records.

Can I fix a GMC problem by waiting?

For conditional bars, yes: once the act is outside the 5-year (or 3-year) period, it no longer automatically bars you, though the officer can still consider it. Permanent bars can't be fixed by waiting.

Will USCIS contact my neighbors?

It can. Since August 2026, USCIS generally conducts neighborhood investigations unless it waives them. Voluntary character reference letters are considered when deciding whether to waive one.
