Before you worry about whether a past mistake will block your citizenship, it helps to know what USCIS looks for. Most of the issues applicants ask about are not disqualifying, and even a real problem often leaves you with options.

What good moral character actually means for naturalization
Good moral character (GMC) is one of the core requirements for U.S. citizenship. According to USCIS, it means your character "measures up to the standards of average citizens of the community in which you reside" (USCIS Policy Manual, Vol. 12, Part F, Ch. 1).
Since August 2025, USCIS has moved from a "neutral" evaluation to requiring affirmative positive evidence of good character. Under the memo that made this change (PM-602-0188), officers consider your community involvement, employment history, tax compliance, and family responsibility rather than simply checking whether you committed specific disqualifying acts.
The statutory period for GMC depends on how you're applying:
| Pathway | GMC Period Required |
|---|---|
| General 5-year rule | 5 years before filing through oath |
| Married to U.S. citizen | 3 years before filing through oath |
| Military during hostilities | 1 year |
Your conduct during this period matters most, but USCIS can also consider earlier behavior if it shows a pattern relevant to your current character (INA § 316(e)).
For a complete overview of all naturalization requirements, see our step-by-step N-400 guide.
Permanent bars that will always disqualify you
Some conduct permanently bars you from establishing good moral character. No amount of time, rehabilitation, or evidence of reform will overcome these:
Murder conviction. Any conviction for murder, at any time in your life, permanently bars citizenship (INA § 101(f)(8)).
Aggravated felony after November 29, 1990. The category is broader than the name suggests. It covers murder, rape, sexual abuse of a minor, drug trafficking, firearms trafficking, money laundering over $10,000, theft or burglary with a one-year sentence, and fraud causing losses over $10,000 (8 CFR § 316.10(b)(1)(ii)).
Persecution, genocide, or torture. Anyone who ordered, incited, assisted, or participated in persecution, genocide, or torture is permanently barred (INA § 101(f)(9)).
If any of these apply to you, consult an immigration attorney before filing. Applying with a permanent bar can trigger removal proceedings.
Conditional bars that apply during your statutory period
These bars only prevent GMC if the conduct occurred during your statutory period. Once enough time passes, the bar no longer applies automatically, though USCIS may still consider the underlying conduct.
Criminal conduct
Crimes involving moral turpitude (CIMT) include fraud, theft with intent to permanently deprive, assault with intent to cause serious harm, and most sexual offenses. There's an exception for "petty offenses" where the maximum possible sentence was one year or less and your actual sentence was six months or less (8 CFR § 316.10(b)(2)(i)).
Multiple criminal convictions with aggregate sentences of five years or more create a conditional bar (INA § 101(f)(3)). This counts all convictions combined, not just related offenses.
Incarceration for 180 days or more during the statutory period is a conditional bar, regardless of what crime led to the incarceration (INA § 101(f)(7)).
If you're wondering whether you can apply while on probation, it depends on your case. Most applicants wait until probation ends.
Drug-related issues
Any controlled substance violation during the statutory period creates a conditional bar. This includes possession, distribution, or any involvement with drugs under federal, state, or foreign law (8 CFR § 316.10(b)(2)(iii)).
The only exception is a single offense of simple possession of 30 grams or less of marijuana. But even this requires careful handling since USCIS can deny based on admission of use alone, without any conviction.
DUI convictions
A single DUI doesn't automatically bar citizenship. However, two or more DUI convictions during the statutory period create a rebuttable presumption that you lack good moral character under Matter of Castillo-Perez, 27 I&N Dec. 664 (A.G. 2019). This means you can overcome it with strong evidence of rehabilitation, but the burden shifts to you.
For detailed guidance on DUI and citizenship, see our complete guide: Can I Apply for Citizenship With a DUI?
Other conditional bars
False testimony under oath to obtain an immigration benefit bars GMC even without a conviction. Under Kungys v. United States, 485 U.S. 759 (1988), the false statement doesn't need to be material. Simply making it with intent to deceive triggers the bar.
Prostitution or commercialized vice within the past 10 years creates a bar (INA § 212(a)(2)(D)).
Two or more gambling convictions or earning income principally from illegal gambling are conditional bars (INA § 101(f)(4), (5)).
Habitual drunkenness during the statutory period can bar GMC (INA § 101(f)(1)).
Non-crime issues that affect good moral character
Criminal history isn't the only GMC concern. USCIS also looks at these issues:
Tax compliance
Failing to file required tax returns can lead USCIS to find you lack good moral character as an "unlawful act" during the statutory period (8 CFR § 316.10(b)(3)(iii)). Owing money to the IRS is often treated as less serious than failing to file, especially if you are current on filing and have an approved payment plan.
For detailed guidance, see N-400 with Tax Issues: Back Taxes, IRS Debt, and Missing Returns.
Child support arrears
Willful failure to pay court-ordered child support adversely reflects on moral character (8 CFR § 316.10(b)(3)(i)). If you're behind, get on an active payment plan and document your compliance before applying.
Selective Service registration
Men who were required to register for Selective Service between ages 18-26 but failed to do so face additional scrutiny. If you're between 26-31, you'll need a Status Information Letter from Selective Service explaining why you didn't register. After age 31, the issue generally becomes less significant, though USCIS may still ask about it.
False claims to U.S. citizenship
USCIS has paid closer attention to this since August 2025. Checking "U.S. citizen" on employment documents or voter registration materials can hurt your good moral character case and can also create immigration consequences. In August 2025, USCIS updated its Policy Manual guidance to clarify how it applies Matter of Zhang, 27 I&N Dec. 569 (BIA 2019), to the false claim to U.S. citizenship ground of inadmissibility. Under that guidance, the statute does not require a false claim to be made intentionally, knowingly, or willfully to trigger inadmissibility, subject to narrow statutory exceptions.
Unlawful voting
Voting unlawfully in a federal election can be treated as an unlawful act affecting good moral character. The Policy Manual's good moral character guidance also covers unlawful voter registration.
What does NOT automatically disqualify you
Some issues that worry applicants won't bar citizenship:
A single DUI is not an automatic bar. You'll need to disclose it and may face extra scrutiny, but one conviction on its own rarely prevents approval.
Minor traffic tickets don't affect GMC. However, you must still disclose all citations on Form N-400. Learn more: Traffic Tickets and Citizenship: Will They Affect Your N-400?
Dismissed charges must be disclosed but aren't automatic bars. USCIS evaluates the underlying conduct, not just the final disposition.
Expunged records must be disclosed. Under Matter of Roldan-Santoyo, 22 I&N Dec. 512 (BIA 1999), expunged convictions still count for immigration purposes. USCIS will see them in your FBI background check anyway.
Old crimes outside the statutory period aren't automatic bars, though USCIS may consider them if they show a relevant pattern.
Bankruptcy doesn't automatically affect GMC. See N-400 After Bankruptcy: Does It Affect Your Citizenship?
The August 2025 policy changes you need to know
The August 2025 USCIS policy memorandum (PM-602-0188) changed how officers evaluate GMC:
Totality of circumstances approach. Officers now weigh both negative conduct and positive attributes. This means evidence of community involvement, stable employment, volunteer work, and family responsibility can strengthen your case.
Positive evidence matters. USCIS now looks for affirmative proof that you're a good member of your community. Strong applications include:
- Employment history showing stability and responsibility
- Tax transcripts demonstrating consistent filing and payment
- Evidence of community involvement (volunteer work, religious participation, civic engagement)
- Character reference letters from employers, neighbors, community leaders
- Evidence of supporting family members
Neighborhood investigations resumed. For the first time since 1991, USCIS may contact your neighbors to verify your character. It won't happen in every case, but officers can do it again.
Enhanced scrutiny of "lawful but questionable" conduct. Even conduct that isn't illegal may receive more attention if it suggests character issues.
What to disclose on Form N-400 Part 9
The questions in Part 9 of Form N-400 are where most GMC issues surface. You must answer honestly about:
All arrests, even if charges were dismissed, you were found not guilty, or records were sealed or expunged
All citations, including traffic tickets
Crimes you weren't arrested for if you committed them (this is the question people tend to miss)
Any involvement with criminal activity, even without arrest

How to prove good moral character
Under the 2025 policy, passive compliance isn't enough. Build a strong case with:
Documentation of positive factors:
- Tax transcripts for the statutory period
- Employment verification letters
- Volunteer service records
- Community organization memberships
- Religious institution participation letters
Character reference letters from people who know you well. The best letters come from:
- Current or former employers
- Community leaders
- Religious leaders
- Long-term neighbors
- Professional colleagues
Letters should describe specific examples of your character, not just general praise.
Rehabilitation evidence if you have past issues:
- Completion certificates for treatment programs
- Counseling records
- Community service documentation
- Time elapsed since the incident
- Evidence of changed circumstances
For a complete list of what documents to prepare, see our N-400 Document Checklist.
What happens if USCIS denies your application for GMC
USCIS does deny naturalization applications, and good moral character is one of the common reasons. A denial is not the end, though.
Form N-336 lets you request a new hearing before an immigration officer if your Form N-400 is denied after your eligibility interview.
The N-336 costs $780 (online) or $830 (paper) and should be filed within 30 calendar days of receiving the N-400 denial decision (or within 33 calendar days if USCIS mailed the decision). You'll get a fresh review of your entire application.
Federal court review is available if your N-336 appeal is denied. This requires filing in U.S. District Court and typically needs an attorney.
Wait and refile is sometimes the best option if your issue is a conditional bar that will expire after more time passes.
