EB‑1A Recommendation Letter Sample: What to Include (With Examples)

EB-1A recommendation letters help tell the story behind an applicant’s accomplishments. Written by experts, colleagues, or other professionals familiar with the applicant’s work, these letters provide context about their achievements, contributions, and impact in the field. Although USCIS does not require recommendation letters, they can help an officer understand highly specialized work and, more importantly, why the applicant’s accomplishments are significant within the field.

The best letters tie the work to one or more of the EB-1A eligibility criteria. They also back up evidence already in the file, such as awards, press coverage, or pay records.

What is an EB-1A recommendation letter?

An EB-1A recommendation letter can come from a respected peer, expert, or industry leader. It supports a claim of extraordinary ability and shows USCIS how people in the field view the applicant’s work.

Why are these letters important?

An EB-1A petition must demonstrate sustained national or international acclaim, but the USCIS officer reviewing the case may not be an expert in the applicant’s field. Recommendation letters can provide valuable context by explaining the significance of the applicant’s work, how it has influenced the field, and why their accomplishments distinguish them from others in the profession. Strong letters can also help connect the documentary evidence in the petition to the broader story of the applicant’s impact.

Letters bridge that gap. They explain the applicant’s work in plain terms and add context. They carry more weight when documents in the file back up what they say.

Who should write EB-1A recommendation letters?

Recommenders should be respected in the field, know the applicant’s work well, and be able to explain why it stands out. They may include:

• Recognized industry experts
• Peers in the same field
• Leaders of professional associations
• Current or former employers or supervisors
• Mentors, professors, or other academic contacts
• Award committee members
• Notable collaborators or clients

USCIS tells officers to weigh how the writer knows the applicant. It also expects acclaim to reach “well beyond the circle of their personal and professional acquaintances.”

The same guidance applies to EB-1B petitions. Strong letters describe the contribution and explain how the writer knows the field.

Are EB-1A recommendation letters required by USCIS?

USCIS rules don’t require recommendation letters, either for employer-filed cases or for applicants self-petitioning for EB-1A. But USCIS guidance says letters can be helpful evidence for some criteria, such as original contributions and a leading or critical role.

Officers weigh letters because they add an outside perspective. A detailed letter from an expert can explain the impact of an applicant’s work. USCIS says letters work best when documents in the file back them up.

Without letters, some criteria may be hard to prove with documents alone. For a pending patent, USCIS generally wants proof of originality, “such as detailed reference letters.”

Do EB-1A letters need to be on official letterhead?

USCIS doesn’t require official letterhead, b. But it helps an officer confirm who wrote the letter. A strong letter pairs letterhead with the writer’s signature, date, title, and contact details.

Some writers can’t use their employer’s letterhead due to company policy or they may not work at a company. In that case, personal letterhead can work. It should show the writer’s name, title, and affiliation. Attaching their CV helps show their standing in the field.

Key elements of a strong EB-1A recommendation letter

Strong EB-1A recommendation letters share a few key elements.

1. Detailed description of the applicant’s abilities

The letter should describe what makes the applicant stand out in the field, including their skills, leadership, reputation, and major contributions. This detail often supports the leading or critical role criterion, one of the 10 EB-1A eligibility criteria.

2. Evidence of extraordinary ability

The letter should also point to concrete proof of the applicant’s ability, such as:

• Nationally or internationally recognized prizes or awards
• Published works, patents, or other original contributions
• Membership in associations that require outstanding achievements
• Major media coverage of the applicant’s work

One letter can touch on several criteria, from awards to published material. Each claim is stronger when it’s backed up by documentation, such as the award notice or the article.

3. Personalized examples and impact

Be specific, not vague. A strong letter gives concrete examples of how the applicant’s work challenged norms, drove new ideas, or changed the field.

4. Professional tone and structure

Each letter should be formal in tone and clear in structure. It should:

• Open with a formal greeting, such as “To Whom It May Concern”
• Include the writer’s full name, title, credentials, and contact information
• Follow a clear, easy-to-read structure
• Use formal, respectful language
• Be signed and dated
• Be on official letterhead (where possible)

Common mistakes to avoid in EB-1A recommendation letters

Understanding how to write EB-1A recommendation letters is important. But so is understanding how not to write EB-1 recommendation letters.

Some of the common mistakes recommenders make when writing support letters include:

1. Vague or generic language

Vague, generic statements like “He’s great to work with” or “She’s well known in our field” are never going to be as impactful as more specific examples. Make sure that letters of recommendation include specific examples and praise (as well as evidence to back up any claims).

2. Overly technical jargon

As mentioned, USCIS reviewers may or may not be familiar with the applicant’s field. And even if they are familiar with the field, chances are they are not familiar with the field’s vocabulary. As such, it’s important to avoid using overly complex, technical, and/or industry-specific terms that might cause confusion.

3. Failure to address USCIS criteria

Don’t expect USCIS reviewers to make the connection between the applicant’s abilities, experience, and contributions and theEB-1 eligibility criteria. Instead, make sure that letters of recommendation speak directly to the criteria and clearly outline the applicant’s qualifications and how they align with EB-1A requirements.

How many recommendation letters are required for an EB-1A Green Card?

While there’s no required number of EB-1A recommendation letters, applicants should aim to include at least three (and up to 10) in their immigration petition. But it’s not just the number of letters; it’s the quality of those letters.

Make sure that every letter in the EB-1A petition is from reputable and credible sources in the applicant’s field. Ideally, there should be a diverse set of recommenders who can each speak to different aspects of the applicant’s talents and achievements (for example, leadership skills, industry innovation, or technical expertise).

Strong letters, strong applications

Manifest attorneys can help EB-1A applicants choose recommenders and match each letter to the criteria. Talk to an EB-1A attorney about which achievements to document and who should vouch for them. Applicants preparing an O-1 petition instead should see our O-1 recommendation letter samples.

FAQs about EB-1A recommendation letters

Are recommendation letters required for EB-1A?

No, USCIS doesn’t require them. But USCIS guidance says letters are helpful evidence for some criteria, such as original contributions and a leading or critical role.

Do EB-1A recommendation letters need letterhead?

No, but letterhead helps an officer confirm who wrote the letter. A writer without it can use personal letterhead with their name, title, and affiliation.

How many recommendation letters should an EB-1A petition include?

USCIS doesn’t set a number, but petitions often include at least three and up to 10. Quality counts more than quantity, and each letter should cover a different aspect of the applicant’s extraordinary ability.

Who should write an EB-1A recommendation letter?

The best writers are respected experts who know the applicant’s work well, including people outside the applicant’s company, who can show how their acclaim extends beyond their immediate circle.

What’s the difference between a recommendation letter and an expert opinion letter?

A recommendation letter comes from someone who knows the applicant or has worked with them. An expert opinion letter comes from an outside expert, often one who hasn’t worked with the applicant, who can judge their impact on the field at large.
