In the EB-1A immigrant visa process, recommendation letters—often called expert opinion letters—serve as critical evidence to establish that a petitioner possesses extraordinary ability in their field. While these letters can come from a variety of sources, not all carry the same weight. A recurring question among attorneys and petitioners alike is: who should write these letters, and how should they be evaluated?
This article explores the evidentiary role of expert letters in EB-1A cases, focusing on letters from independent experts versus managers or co-workers, the legal expectations behind them, and the strategies available when certain letters cannot be obtained. It also examines the regulatory and case law foundations underlying USCIS’s treatment of testimonial evidence.
Letters from Managers and Co-Workers: Are They Useful?
Letters from managers and co-workers can indeed support an EB-1A petition, particularly when trying to establish that the petitioner has played a leading or critical role in a distinguished organization under 8 CFR § 204.5(h)(3)(viii). These letters are most persuasive when the author holds a senior leadership role, has direct knowledge of the petitioner’s work, and can clearly articulate how that work advanced the organization’s mission or had tangible impact on high-value outcomes. That said, such letters are frequently viewed with skepticism by USCIS adjudicators due to potential bias. The underlying concern is that these authors have a vested interest in the petitioner’s continued employment or are personally connected to them. Moreover, letters from internal personnel often fail to demonstrate how the petitioner’s contributions have impacted the field more broadly, which is a fundamental requirement under the EB-1A framework.
Is It Acceptable to Omit Employer Letters?
Yes, absolutely. There is no legal obligation to submit letters from the petitioner’s employer in an EB-1A petition. The evidentiary burden is not to demonstrate exceptional job performance, but rather to establish sustained national or international acclaim in the field of endeavor. In many strong EB-1A cases, the petition is supported entirely through independent evidence, such as peer-reviewed publications, citation data, patents, invited presentations, and expert letters from outside authorities. However, if the petitioner intends to rely on the “critical role” criterion, then the absence of employer letters or declarations can be a significant evidentiary gap. This is because only someone internal to the organization can credibly speak to the company’s reputation and how the petitioner’s work contributed to its success.
Proving “Critical Role” Without Employer Letters
For petitioners who are unable to obtain letters from managers or co-workers—whether due to company policy, risk of retaliation, or other obstacles—alternative forms of evidence may be used to demonstrate that they played a critical role. This includes independent expert letters from individuals who are familiar with the petitioner’s work and its outcomes, even if they are not internal to the organization. Petitioners can also include detailed project documentation showing their leadership, authorship, or technical contributions; internal charts or dashboards indicating their position in the hierarchy; and screenshots of project ownership in platforms like JIRA or GitHub. Media coverage, patents, product launch materials, or third-party recognition may also support the narrative. Financial data, user adoption metrics, or performance benchmarks linked to the petitioner’s work can further illustrate how their role was not just technical, but central to the success of the product or organization.
Although these substitutes do not carry the same direct testimonial weight as a manager’s letter, when carefully assembled and coherently presented, they can form a persuasive record that satisfies the “critical role” prong.
Personal Affidavits from Co-Workers or Former Managers
In cases where a company refuses to issue letters on official letterhead, it is both acceptable and legally valid to use personal affidavits or unsworn declarations from individuals with firsthand knowledge of the petitioner’s work. This practice is explicitly supported by 8 CFR § 103.2(b)(2)(i), which allows the use of affidavits when primary evidence is unavailable for reasons beyond the applicant’s control. The affidavit should be executed under penalty of perjury pursuant to 28 U.S.C. § 1746, and should include a brief statement clarifying that the declarant is providing the letter in a personal capacity due to company policy.
Effective affidavits include the declarant’s full name, title, years of experience, and relationship to the petitioner. The statement should describe the petitioner’s responsibilities, specific accomplishments, and measurable impact on the organization or projects at issue. It is critical that these letters do not resemble employment verification letters; rather, they should focus on innovation, field impact, and organizational outcomes consistent with the EB-1A evidentiary standard.
Identifying Independent Experts to Write Letters
Finding truly independent experts is often one of the most challenging aspects of the EB-1A process. Still, there are several effective strategies. Petitioners should begin by reviewing who has cited their work using tools like Google Scholar, Scopus, or Web of Science. Authors who have cited the petitioner’s publications—but who have not collaborated directly—can be excellent sources of independent testimonial evidence.
Professional associations are also valuable resources. Senior members of organizations such as IEEE, ACM, AMA, or ASME may be willing to provide expert evaluations. Editorial board members of journals where the petitioner has published are another strong category, particularly if they are familiar with the significance of the petitioner’s contributions in context.
In addition, conference chairs, keynote speakers, and thought leaders in the petitioner’s industry can be contacted directly through platforms like LinkedIn or ResearchGate. Petitioners can explain their situation, share a list of accomplishments, and offer to provide a draft letter for the expert’s review and customization.
Do Evaluation Agencies Offer Expert Letters for EB-1A?
Yes, some credential evaluation agencies—especially those that provide expert letters for H-1B specialty occupation RFEs—also offer services to generate recommendation letters for EB-1A petitions. These agencies typically work with Ph.D.-level academics or professors who can issue opinion letters on university letterhead. While this may sound attractive in theory, attorneys and petitioners must exercise caution. Many of these letters are template-driven, generic, and not based on personal familiarity with the petitioner’s work. As such, they often lack probative value in the EB-1A context, where USCIS expects detailed, personalized evaluations based on the expert’s actual knowledge of the petitioner’s achievements.
It is also important to be aware that USCIS has denied EB-1A petitions in which expert letters appeared to be “purchased endorsements” rather than genuine evaluations. If a petitioner chooses to work with such an agency, they should ensure that the expert is indeed qualified in the field, has some familiarity with the petitioner’s work, and is willing to sign a letter that accurately reflects the work’s impact, originality, and influence.
Why USCIS Requires “Actual Awareness” of the Petitioner’s Work
Independence alone is not sufficient for a letter to carry weight in an EB-1A petition. USCIS places significant emphasis on whether the expert has actual knowledge of the petitioner’s work and can credibly evaluate its significance. This expectation is clearly reflected in both the USCIS Policy Manual and in multiple non-precedent AAO decisions.
Volume 6, Part F, Chapter 5 of the USCIS Policy Manual instructs adjudicators to consider the author’s expertise, relationship to the petitioner, and the specificity and probative value of the letter. Letters from individuals who are merely prestigious but cannot explain how they became familiar with the petitioner’s work are typically disregarded.
This principle is reinforced by the AAO in cases like Matter of V-K- (Sept. 2020), where the appeals officer dismissed letters that did not establish how the authors became familiar with the petitioner’s contributions or assess their impact in the field. Similarly, in Matter of L-T-C- (Feb. 2018), the AAO rejected testimonial evidence on the grounds that the letter writers failed to indicate how they knew the petitioner’s work or provide specific examples of its influence.
In short, the most persuasive letters come from independent experts who are not only qualified in the field, but who can also explain how they became aware of the petitioner’s work—whether through reading, citing, using, reviewing, or evaluating it—and why it is considered original, influential, or significant.
Final Thoughts
In EB-1A adjudication, expert letters remain one of the most powerful tools for substantiating a petitioner’s extraordinary ability. But their value hinges on content, credibility, and context. USCIS expects these letters to be independent, specific, and based on genuine awareness of the petitioner’s work—not vague praise or legal conclusions. While employer letters are not mandatory, they can be important when claiming a leading or critical role. Where such letters are unavailable, affidavits, project documentation, and objective data can help fill the gap.
Attorneys representing EB-1A applicants should carefully balance the evidentiary portfolio to ensure that each letter adds something meaningful to the overall record, and that all testimonial evidence—whether from insiders or independent experts—is crafted with the standards of credibility, relevance, and specificity in mind.
