Establish the writer.
Explain the writer’s position, expertise and ability to evaluate the applicant’s research.
Research Immigration Evidence
Recommendation Letters for Research Immigration Petitions
A strong recommendation letter does more than describe a researcher as talented or accomplished. It explains specific facts: what the researcher contributed, how the writer knows about the work, why the contribution matters and what objective evidence supports the claim.
Specific beats enthusiastic Detailed facts usually add more value than
adjectives such as exceptional or groundbreaking.
Independent does not mean uninformed A writer should explain how they became familiar
with the researcher’s work.
Letters should fit the legal issue EB1A, EB1B and NIW letters should not all
make the same argument.
Letter Architecture
Four Parts Make a Research Letter Useful.
Explain the relationship.
State whether the writer supervised, collaborated with, cited, reviewed, used or independently learned of the applicant’s work.
Identify the contribution.
Describe a specific finding, method, technology, program or body of research rather than the researcher’s career generally.
Explain why it matters.
Connect the factual claim to citations, adoption, implementation, funding, institutional use or another objective record.
Who Should Write?
Different Writers Prove Different Things.
Supervisor or Manager
Strong for internal facts.
A manager may be particularly useful for explaining the researcher’s responsibilities, critical role, project implementation and organizational impact.
Collaborator
Strong for technical detail.
A collaborator may have firsthand knowledge of the research methods, discoveries and the applicant’s individual contribution.
Independent Expert
Strong for outside recognition.
An independent expert can be especially useful when they can explain how the research became known or influential outside the applicant’s immediate professional circle.
Stronger Letter Content
Replace Conclusions With Verifiable Facts.
Specific Contribution Name the discovery, method, system,
paper or research program.
Independent Use Explain who adopted, cited,
implemented or extended the work.
Research Impact Describe the scientific, technical,
clinical or institutional consequence.
Individual Role Separate the applicant’s work from
the achievements of the larger team.
Comparative Context Explain why the achievement is unusual
when the writer has a reliable basis to do so.
Objective Corroboration Point to citations, adoption records,
patents, grants or other documentation.
Basis of Knowledge Explain whether knowledge comes from
direct work, citation or independent use.
Legal Relevance Address the factual issue the petition
actually needs to establish.
Weak vs. Strong
Avoid Letters That Could Describe Any Researcher.
Weak
“Dr. X is one of the best researchers in the field.”
The statement is a conclusion unless the writer explains the facts and basis for that assessment.
Stronger
Explain the event that supports the conclusion.
Identify the contribution, outside adoption, measurable result and documentary evidence that caused the writer to reach that view.
Category Specific Use
The Same Letter Should Not Be Used the Same Way Everywhere.
Category Useful Letter Topics Central Question
EB1A Contributions, independent recognition,
critical role and research influence What does the record show about extraordinary ability?
EB1B Research contributions and international recognition Is the researcher internationally recognized as outstanding?
NIW Proposed endeavor, prior success, support,
progress and prospective significance How does the evidence support the NIW prongs?
National Interest Waiver
NIW Letters Require a Different Strategy From EB1A Expert Letters.
Common Questions
Research Recommendation Letter FAQ
How many recommendation letters are required?
USCIS does not establish a universal required number of recommendation letters for EB1A, EB1B or NIW petitions.
Are independent letters always better?
Not automatically. The value of the letter depends on what the writer can reliably explain and how the testimony fits the rest of the evidence.
Should every letter describe every accomplishment?
Usually not. Different writers can address different contributions or evidentiary issues based on their actual knowledge.
Should letters repeat the legal standard?
Factual, specific testimony is generally more useful than having an expert simply repeat legal conclusions.
