Yes, a criminal conviction can prevent you from becoming a U.S. citizen.
The bar depends entirely on the crime: some convictions permanently block naturalization no matter when you file, while others prevent it only if the conviction occurred within a set time before your application. Naturalization requires establishing good moral character, a legal standard USCIS evaluates case by case. A conviction—whether recent or decades old—can trigger a bar that either blocks you outright or forces you to clear a high threshold to move forward.

Permanent Bars to Citizenship
Murder and aggravated felonies carry permanent bars, with no window for redemption. A murder conviction at any time disqualifies an applicant permanently, regardless of when the crime occurred or how long ago. Under federal law, an aggravated felony conviction entered after November 29, 1990, is an automatic and permanent bar to establishing good moral character.
Aggravated felonies are broadly defined. The law includes illicit drug trafficking, crimes of violence with at least a one-year sentence, sexual abuse of a minor, and fraud involving losses over $10,000. If your conviction falls into one of these categories, naturalization is not available unless the conviction is successfully vacated or set aside on grounds other than rehabilitation.
Crimes of Moral Turpitude and the Statutory Period
Not all criminal convictions create permanent bars. Crimes of moral turpitude (CIMT)—such as theft, fraud, or dishonesty—bar naturalization only if they occurred within the statutory period, typically five years before you file your citizenship application. If a CIMT conviction is older than five years and no other bar applies, you may still qualify.
For applicants married to a U.S. citizen and living with that spouse, the statutory period is shortened to three years. This shorter window applies only to crimes of moral turpitude; permanent bars like aggravated felony convictions ignore timing entirely.
Why the Timing of Your Conviction Matters
The effective date November 29, 1990, divides the law. Pre-1990 convictions are not automatic permanent bars under the aggravated felony rule and are evaluated with more discretion under the general good moral character standard, though they still weigh heavily in USCIS's determination. A conviction from 1985 will be examined, but it is not a categorical disqualification.
The statutory period also creates a five-year window that looks backward from your application filing date. A DUI, theft, or assault conviction from six years ago may no longer bar you from demonstrating good moral character, but one from two years ago does. This timing is crucial: the same crime can either block your path or leave it open depending on when it was committed.
Multiple Violations and Discretionary Denials
Repeated offenses can trigger presumptions against good moral character. Multiple DUI convictions within the statutory period create a legal presumption that you lack good moral character, though you may present evidence to rebut it. This means the burden shifts to you to prove your character despite the convictions. Beyond statutory categories, USCIS officers retain discretion to evaluate any criminal conduct during the statutory period.
Even a misdemeanor or conduct that does not fit a legal definition can be weighed against you if the officer determines it reflects poorly on your moral character. This discretion means your entire history—not just formal convictions—may be considered.
The Burden of Proof and Vacated Convictions
You bear the legal burden of proving good moral character; a criminal conviction during the statutory period shifts the weight against you. Even a conviction that is later vacated, set aside, or dismissed on rehabilitation grounds still counts as a bar to establishing good moral character in naturalization proceedings. State law may offer relief, but immigration law does not recognize it.
If you have a criminal conviction and are considering naturalization, consult an immigration attorney immediately. The distinction between permanent bars, statutory-period bars, and discretionary denials requires case-specific analysis. An attorney can determine whether your conviction blocks you, examine whether vacating it under state law is possible, and advise on timing.
Frequently Asked Questions
Does a misdemeanor bar me from naturalization?
Misdemeanors are generally not automatic bars unless they constitute crimes of moral turpitude. A simple misdemeanor (like a traffic violation) typically does not prevent naturalization. However, USCIS may consider any criminal conduct when evaluating your overall moral character.
Can I become a citizen if my conviction was a long time ago?
It depends on the crime. Permanent bars (murder, aggravated felonies) have no time limit—they block you forever. Other crimes bar you only if they occurred within five years (or three years if married to a U.S. citizen) of filing your citizenship application.
What if I got my conviction expunged?
Expungement or vacation under state law does not erase the immigration bar. Even if your state treats the conviction as dismissed, USCIS still counts it against your naturalization application.
