In almost every situation in which people apply for a long-term U.S. immigration benefit, whether they're avoiding deportation or applying for naturalized citizenship, the U.S. government will consider their moral character. Good moral character is especially important in situations where the decision-maker has some discretion; in other words, isn't obligated to grant the immigration benefit without believing that the applicant somehow deserves the favor.
In many situations, however, applicants are required to show "good moral character" as an explicit part of the application. For example, for naturalized U.S. citizenship or cancellation of removal for non-lawful permanent residents, applicants must show that they have had good moral character (GMC) for a certain period of time, as specified by federal statute.
U.S. Citizenship and Immigration Services (USCIS) and the Department of State (DOS) decide whether an applicant has met the GMC requirement on a case-by-case basis. It doesn't mean being a saint. In the past, it basically meant that your behavior measured up to the standards of average citizens living in your community.
However, in late 2025, USCIS started issuing indications that it seeks to raise this good moral character standard, particularly in the naturalization (citizenship) context. It issued an August 2025 memo stating that naturalization applicants will now need to show "sustained community involvement and contributions" to this country, and listed the following possible indicators of GMC:
While there's been no official policy change extending these measures of GMC to areas beyond U.S. citizenship, it's a probable sign of a trend.
U.S. immigration law provides specific guidance as to what isn't "good moral character" at Immigration and Nationality Act Section 101(f), 8 U.S.C. 1101(f). If you commit certain acts or hold a certain status within the time period that the particular benefit you're seeking requires showing good moral character for, you can be found to automatically lack it, regardless of the underlying circumstances of the event.
The acts that block a good moral character finding include:
In addition, the U.S. government can consider other acts that fall outside of the specific statutory period in assessing good moral character, and may determine that these show that you lack it.
Regardless of the type of application, you will probably be asked to provide evidence of your clean criminal and immigration record, thus hopefully overcoming the bars to good moral character described above.
But if you're dealing with the type of application that explicitly requires proving good moral character, or if you have some minor blot on your record that needs outweighing, you might need to provide more than that. This could include, for example, a:
The more detail you can provide in such a statement or letter, the better. In other words, a letter saying that, "My employee Mr. X has good moral character," is far weaker than one saying "My employee Mr. X has been a trusted assistant to the director for 12 years, always available for extra work and able to scrupulously maintain confidential information."
In some situations, you might not be specifically required to show good moral character, but it will still be considered before U.S. immigration officers will approve your application for an immigration benefit. For example, your moral character might be considered indirectly, or might be taken into account in an officer's legal discretion.
Applications for an immigrant visa (a green card) or nonimmigrant (temporary) visa, for instance, do not specifically require that you show good moral character. But they do require that you have not committed certain acts, like certain crimes, fraud, or immigration violations. These grounds of inadmissibility are thus tied to your good moral character.
In addition, when considering visa applications, the U.S. government can deny admission as a discretionary matter even if you are not technically inadmissible. Also, a history of questionable moral acts might make the officer wonder whether you will comply with the basic terms of the visa you're applying for, as opposed to flouting the law and, say, failing to leave the United States when you are supposed to.
Be prepared to address any negative issues in your case, even if they do not automatically bar you from the eligibility for the benefit. It is better to present a strong application affirmatively than try to reverse a negative decision against you.
If you are denied an immigration benefit as a matter of the government's discretion, it is usually difficult to appeal it. It is therefore important, before you apply for a visa, green card, or other immigration benefit, to know whether the benefit has an explicit or implicit good moral character requirement and what acts might disqualify you from the benefit. It would be worth consulting with an experienced immigration attorney to help with this analysis. See Is an Immigration Lawyer Worth the Cost?.
