To write a letter of good moral character, open by identifying yourself and explaining exactly how you know the subject, then devote the body to specific firsthand examples that show the qualities you are claiming, and close with a clear statement of support. Keep it to one page, match the content to what the requesting agency actually weighs, and sign only what you personally know to be true.
Most letters fail in the same way: they stack adjectives without evidence. A reviewer reading “honest, hardworking, and compassionate” without a single story behind those words learns nothing about the subject. A reviewer reading about the time you watched the person return a wallet, cover a coworker’s shift during a family crisis, or follow through on a promise when no one was checking learns everything.
Start by Finding Out What the Recipient Actually Wants
Before you write a sentence, find out what the requesting court, agency, or board expects. The qualities that matter shift sharply by context.
- For U.S. citizenship applications, USCIS does not formally require character letters with the N-400, but applicants sometimes submit them to strengthen a borderline case or address past issues. Content should speak to community ties, steady employment, compliance with laws, and fulfillment of obligations like taxes and child support.
- For criminal sentencing, defense attorneys typically collect three to six strong letters rather than a thick stack of weak ones. The letters go through the defense attorney, never directly to the judge or prosecutor.
- For professional licensing (bar admissions, medical boards, and similar bodies), some authorities require references who have known the applicant continuously for five years and are not related by blood or marriage.
- For adoption, home study evaluators usually ask for three to five letters speaking to stability, parenting ability, and character.
- For employment and security clearances, background investigators often contact references by phone after reading the written letter, so what you write needs to match what you can say out loud later.
One boundary worth knowing: in immigration law, “good moral character” is a defined legal term with specific statutory disqualifiers and look-back periods.1eCFR. 8 CFR 316.10 – Good Moral Character Your letter does not decide eligibility; it adds to the record USCIS reviews. Claiming the subject has “always followed the law” when a conviction is in the file damages your credibility and theirs.
Choose the Right Person to Write It
The writer’s relationship to the subject is the single biggest factor in whether the letter carries weight. Reviewers want to hear from people who have observed the subject’s behavior firsthand over a meaningful stretch of time.
Strong references include long-term employers, close colleagues, community leaders such as clergy or volunteer coordinators, teachers or professors, and licensed professionals who have interacted with the subject in a professional capacity. The best writers can describe situations they personally witnessed.
Most requesting agencies prohibit or discourage letters from family members, because a parent or sibling has an obvious stake in the outcome. Even where family letters are allowed, they carry far less weight than one from someone with no personal interest beyond knowing the subject to be a decent person.
For sentencing letters, the writer should be prepared to acknowledge the offense. A letter that pretends the conviction never happened, or tries to minimize it, reads as dishonest. The most effective sentencing letters come from people who know what happened, believe in the person anyway, and can explain why based on what they have seen.
Open by Establishing Who You Are
The first paragraph is the foundation. Give your full name and professional title, explain how and when you met the subject, and state how long you have known each other. Include current contact information so the agency can follow up. A reviewer who cannot tell why you are qualified to speak will not trust what comes next, so this information belongs on page one, not buried later.
If you have a specific recipient, address the letter to them by name and title. If not, “To Whom It May Concern” is acceptable. Use standard business letter format with your address at the top, the date, the recipient block, a formal salutation, body paragraphs, and a complimentary close. Personal or professional letterhead helps if you have it.
Build the Body Around Specific Examples
Each body paragraph should focus on one quality and illustrate it with a real example. Describe a time you watched the subject handle a difficult situation with integrity, step up for someone in their community, or follow through on a commitment when it would have been easier not to. One concrete story outweighs a paragraph of adjectives.
Tailor the examples to the context. For an immigration letter, lean into community ties, steady work, and meeting family and financial obligations, because those are the factors USCIS weighs.1eCFR. 8 CFR 316.10 – Good Moral Character For a sentencing letter, what the subject has done since the arrest often matters more than who they were before. Enrollment in treatment, community service, changed routines, and steps toward accountability signal to a judge that the person is moving in a constructive direction.
If there is a difficult fact in the record, address it directly and then pivot to what has changed. Silence on the elephant in the room reads worse than honest acknowledgment.
Close With a Clear Recommendation
End by saying directly what you are asking the reader to do: grant the application, consider leniency, approve the license. Offer to provide additional information if the recipient wants it. Sign with a handwritten signature when possible. A typed signature works, but the handwritten version signals that you took the process seriously.
Keep It to One Page
Reviewers processing stacks of applications or presentencing packages do not have time for three-page testimonials. A tightly written single page is more persuasive than a rambling longer one. If you genuinely cannot fit your key points into one page, a page and a half is the upper limit.
Signing Under Penalty of Perjury or Getting It Notarized
Some attorneys or agencies ask the writer to sign under penalty of perjury rather than get the letter notarized. Federal law allows this. Under 28 U.S.C. ยง 1746, any statement that would normally require a sworn oath can instead be submitted as an unsworn written declaration if it includes specific language.2Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury
For letters signed inside the United States, the required closing is: “I declare under penalty of perjury that the foregoing is true and correct. Executed on [date].” followed by your signature. For letters signed outside the country, add “under the laws of the United States of America” after “perjury.”2Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury A declaration signed this way carries the same legal force as a sworn affidavit.
Notarization is usually optional. Most courts and agencies do not require character letters to be notarized, though some attorneys recommend it because it verifies the writer’s identity. If the agency’s instructions do not mention notarization, it is generally not necessary. Notary fees vary by state and typically fall between $2.50 and $15 per signature.3National Notary Association. 2026 Notary Fees By State
Mistakes That Undermine the Letter
- Empty adjectives with no stories. Calling someone “reliable” without describing a situation where you saw that reliability means nothing to a reviewer. Every positive claim needs a concrete example.
- Painting a saint. No one is flawless. A letter that presents the subject as perfect reads as either naive or dishonest. Acknowledging a real challenge and explaining how the subject handled it is more persuasive.
- Avoiding the hard fact. If there is a past conviction or a known issue, pretending it does not exist destroys credibility. Name it and move to what has changed.
- Unclear relationship. If the reviewer cannot tell how you know the subject or how long you have known them, the letter has no foundation.
- Wrong register. Casual phrasing (“my buddy Mike is a great guy”) signals you do not understand the stakes. Copying stiff legal boilerplate feels impersonal. Aim for respectful and natural.
Submitting the Letter
Follow the delivery instructions exactly. Some courts require hard copies mailed to the clerk’s office or delivered to the defense attorney for inclusion in a sentencing memorandum. Immigration applications may accept uploads through a USCIS portal. Licensing boards often have their own forms or portals.
For sentencing letters, route the letter through the defense attorney, who will include it in the sentencing package at the right time. Never send it directly to the judge or prosecutor.
Be ready for a follow-up. Background investigators for security clearances and some immigration cases call references to verify what was written. They may also reach out to people the applicant did not list, so what the letter says needs to line up with reality.
Only Write What You Know to Be True
A character letter is a statement submitted to a decision-making body, and lying in one carries real legal risk. Under federal law, anyone who knowingly makes a false statement in a matter within the jurisdiction of the U.S. government faces up to five years in prison.4Office of the Law Revision Counsel. 18 USC 1001 – Statements or Entries Generally If the letter is signed under penalty of perjury, the writer has formally sworn the contents are true.
Include only facts you personally know, label opinions as opinions, and never embellish events. If you are unsure about a detail, leave it out. A shorter honest letter beats a longer one with something an investigator can disprove.
