Key Takeaways About Immigration Reference Letter:
  • »
    A reference letter is a written statement from someone with direct personal knowledge, submitted as evidence in a U.S. immigration filing.
  • »
    Affidavits rank below primary and secondary documents in the evidence hierarchy, so a letter supports a record rather than replacing it.
  • »
    The reference letter must contain the writer's full name and address, date and place of birth, relationship to the parties, and how they came to know what they are stating.
  • »
    You usually do not need to notarize your letter because a signed declaration under penalty of perjury carries the same legal weight.
  • »
    A character reference letter and an O-1 or EB-1A recommendation letter are different documents with different jobs, so make sure to get the right one.

An immigration reference letter is a written statement from someone who knows an applicant, submitted as evidence in a case before U.S. Citizenship and Immigration Services. This article covers the most important elements in an immigration reference letter, who can write it and includes a downloadable template. 

What Is an Immigration Reference Letter?

The letter goes by several names: reference letter, letter of recommendation, letter of support, character letter, and affidavit; all describe the same basic thing: a signed statement of fact from a person in a position to know.

USCIS requires that the reference letter be written by persons who are not parties to the petition, but have direct personal knowledge of the event and circumstances. 

Essentially, the letter must be independent and focus on its primary purpose. This could include discussing your work or work history to establish credibility. It is not meant to simply praise your character. 

A character reference in a family case, an employment letter confirming a work history, and an expert recommendation letter in an O-1 or EB-1A petition are read by different people against different standards, and they are not interchangeable. 

Where a Reference Letter Is Required in the Evidence

USCIS sets a clear priority list for evidence, and reference letters are not the first requirement. The agency looks at evidence in three tiers; 

  • Primary evidence: Official documents required by the regulations. For example, birth or marriage certificates. 
  • Secondary evidence: Alternative official documents used when the primary evidence documents are unavailable, such as church or school records related to the facts. 
  • Affidavits: Sworn written statements from at least two non-parties with direct personal knowledge. Submit them when secondary evidence is also unavailable. 

Use a reference letter when official records do not exist, and explain why those records are missing. USCIS requires at least two affidavits from disinterested third parties, meaning neither the applicant nor the petitioner can write them.

Which Immigration Reference Letter You Are Being Asked to Write

The purpose changes what the letter must say. Before commissioning reference letters, work out which of these you are being asked for.

The case What the letter is asked to prove Who should write it What this means for you
Marriage-based petition or removal of conditions That the marriage is genuine Someone who has spent real time with both spouses Write about occasions you witnessed, not about how happy they seem
Naturalization Good moral character during the statutory period Someone who has known the applicant across years The burden is with the applicant; your letter is one input
Waivers and hardship The effect on a qualifying relative Someone who has seen the hardship directly Dated, concrete observation is better than sentiment
Employment or experience Dates, duties, and seniority The employer, or a supervisor of record This is a records document, and accuracy is important
O-1, EB-1A, EB-2 NIW The applicant's standing in their field An expert qualified to assess it A different document against a different standard

Reference Letter Format for Immigration​

Here are different samples of reference letters for immigration​ purposes by use-case; 

For a Marriage-Based Case

This is the most common reason people are asked. The third party must know the marital relationship. Knowledge is the operative word. A letter that reports specific things you saw over a dated period is better than a letter praising the couple. Our guide to removing conditions covers what that filing involves.

For Naturalization and Good Moral Character

The applicant must demonstrate that during the prescribed period, he or she continues to be a person of good moral character. The assessment is case-by-case, based on the standards of the average citizen in the community of residence.

For an Employment or Experience Letter

This letter confirms dates of employment, job titles, duties, and reporting lines, and it is written by someone with the authority to confirm them. If the dates in the letter differ from the dates elsewhere in the filing, the letter creates a problem.

For an O-1, EB-1A, or EB-2 NIW Petition

In these petitions, a recommendation letter serves as expert testimony. It is written by someone qualified in the applicant's field, it maps to specific regulatory criteria, and it is assessed for both the writer's independence and expertise and what it says. This letter differs from everything above, with its own rules about who should write it, how many are useful, and what triggers a request for evidence. Our guides to O-1 recommendation letters and EB-1A recommendation letters cover both in full.

For Immigration Court

A letter for a bond hearing, or for any matter before an immigration judge, is a different filing in a different forum, decided under the standards of the relief being sought. Anyone in removal proceedings should be working with counsel who handles them.

What the Regulation Says the Letter Must Contain

According to USCIS Regulations, the reference letter must contain four things; 

  • Who you are. Your full name and address.
  • When and where you were born. Your date and place of birth.
  • How you are connected. Your relationship, if any, to the people involved.
  • How you know. In the regulation's words, "complete information and details explaining how the person acquired his or her knowledge."

Everything that separates a statement that helps from one that gets rejected is in how you answer the fourth requirement. 

Does Your Reference Letter Need to Be Notarized?

No, it does not need to be notarized. In most cases, a signed statement under penalty of perjury has the same legal weight as a notarized affidavit. If you are signing in the U.S. (or its territories), use this phrasing: "I declare (or certify, verify, or state) under penalty of perjury that the foregoing is true and correct. Executed on (date). (Signature)."

If you are signing outside the U.S., add one extra phrase: "I declare (or certify, verify, or state) under penalty of perjury under the laws of the United States of America that the foregoing is true and correct. Executed on (date). (Signature)."

Clear, first-hand details strengthen your letter, not a notary stamp. Still, always double-check the specific form instructions for your case, as some filings may still require notarization.

What Weakens a Reference Letter

  • Praise instead of witness. A letter describing someone as honest and hardworking asserts a conclusion. A letter describing what you saw them do, and when, provides evidence.
  • Shared sentences. Where several writers submit letters carrying the same phrasing, the resemblance is visible, and it undercuts all of them at once.
  • The wrong writer. The regulation asks for people "who are not parties to the petition." A letter from the applicant or the petitioner is not an affidavit in the sense the rule means.
  • Assertions with no source. Any statement you cannot connect to something you personally saw or heard belongs out of the letter.

Note: A reference letter in another language needs a full English language translation which the translator has certified as complete and accurate, plus the translator's certification of competence. So write in whichever language you can be precise in, then have it translated properly. It’s better to be more accurate in your language than in English.

Find Out What Your Own Case Needs With Beyond Border

Beyond Border works on employment-based categories, where letters serve as expert testimony, not just character evidence. If you are writing for a colleague, an employee, or a researcher whose achievements might support an O-1, EB-1A, EB-1B, EB-1C, or EB-2 NIW petition, you need to know how to write letters for these petitions. 

Our attorneys will assess whether the profile supports one of those categories, what the letters would need to establish if it does, and which alternative fits better if it does not. Request a case assessment to find out where your profile actually stands.

Frequently Asked Questions

Who can write a reference letter for immigration?

Anyone with direct personal knowledge of the facts, who is not a party to the petition. This rules out the applicant and the petitioner but not friends, neighbours, coworkers, clergy, or employers.

How many reference letters should be submitted?

If the letters will be standing in for unavailable documents, you will need to submit two or more reference letters. No minimum or maximum number is published. It’s always better to have a set of specific letters from different vantage points.

How long should an immigration reference letter be?

There is no required length. The only requirement is that the letter carries the writer’s identity, relationship, and a complete account of how they know what they are asserting. One detailed page usually does that better than three general ones.

Can the applicant write the letter themselves and have someone sign it?

The letter is the signer's statement, made under penalty of perjury, so it must reflect what the signer knows. So the signer must confirm that he or she understands the letter's content and has first-hand knowledge of it before signing.

Can the letter be written in a language other than English?

Yes, it can, but it must be accompanied by a certified English translation, certified by the translator as complete and accurate, along with the translator's certification that they are competent to translate.

Is a reference letter the same as a recommendation letter for an O-1 or EB-1A petition?

No. An O-1 or EB-1A letter is expert testimony about the applicant's standing in their field, written by a qualified expert and mapped to regulatory criteria. A reference letter mostly serves as a character reference for other petitions.
