Independent vs Dependent Recommendation Letters for EB1 and NIW

Researchers preparing EB1A, EB1B or National Interest Waiver petitions often hear that they need “independent recommendation letters.” Independent letters can be valuable, but there is no general USCIS rule requiring every letter to come from someone who has never worked with the applicant.

Dependent and independent writers provide different kinds of evidence. A strong petition uses the writer who is best positioned to establish the particular fact at issue.

What Is a Dependent Recommendation Letter?

The phrase dependent letter is commonly used in immigration practice to describe a letter from someone with a direct professional relationship to the applicant.

Examples may include:

• current supervisors;
• former supervisors;
• principal investigators;
• professors;
• coauthors;
• research collaborators;
• current employers; and
• former employers.

What Is an Independent Recommendation Letter?

An independent writer generally knows the applicant’s work without having supervised, employed or closely collaborated with the applicant.

The writer may know the applicant through:

• publications;
• citations;
• conference presentations;
• professional reputation;
• technology adoption;
• patent use;
• clinical implementation;
• editorial service; or
• other professional exposure.

Independence Is Not a Regulatory Criterion

EB1A, EB1B and NIW do not impose a general rule requiring a fixed number of independent letters.

The evidentiary question is what the writer actually knows and how persuasively the letter supports the relevant facts.

Why Are Independent Letters Useful?

Independent letters can help demonstrate that the applicant’s work has reached people outside the applicant’s immediate professional circle.

This may be useful when the petition argues:

• independent recognition;
• major significance of research;
• broader scientific influence;
• international recognition;
• independent adoption;
• industry impact; or
• professional reputation beyond one employer.

A Genuine Independent Expert Should Know the Work

Independence alone does not make a letter persuasive.

A writer who had never heard of the applicant before being asked to review a CV may have less persuasive evidence of independent recognition than a researcher who previously cited or adopted the applicant’s work.

Strong Basis of Independent Knowledge

A strong independent writer may state:

• “I first learned of the applicant’s work through her publication…”
• “Our laboratory adopted the applicant’s method…”
• “I cited the applicant’s research because…”
• “Our company implemented the applicant’s technology…”
• “I invited the applicant to speak after becoming familiar with…”

This explains why the writer can offer meaningful testimony.

Why Dependent Letters Are Valuable

Direct collaborators often know facts that independent experts cannot know.

A principal investigator may be the best person to explain:

• what the applicant personally developed;
• how responsibilities were divided among coauthors;
• why a research problem was difficult;
• what experiments or methods the applicant created;
• how the applicant led a project; and
• what resulted from the applicant’s work.

Supervisor Letters and Personal Contribution

In collaborative scientific research, USCIS may need evidence distinguishing the applicant’s own contribution from the work of the team.

A detailed supervisor letter can provide first-hand evidence that an independent expert may not possess.

Collaborator Letters

Collaborators can explain technical details and personal responsibilities.

The petition should disclose the collaboration accurately rather than attempt to portray the writer as independent.

Independent Letters and Original Contributions

For EB1A original contributions, an independent expert may be particularly useful when the expert actually relied on or observed the influence of the applicant’s research.

The letter can explain external impact rather than internal project responsibilities.

Dependent Letters and Original Contributions

A supervisor may establish what the applicant created.

An independent expert may establish what happened after the work reached the field.

Used together, the two letters can answer different evidentiary questions.

Independent Letters and EB1A Final Merits

Independent testimony may provide evidence that recognition extends beyond the applicant’s employer or close collaborators.

The testimony should still be corroborated where objective evidence is available.

Independent Letters and EB1B

Because EB1B requires international recognition as outstanding, testimony from independent researchers in different institutions or countries may provide useful context.

Letters are only part of the overall record.

Independent Letters and NIW

NIW does not require independent letters.

USCIS considers support letters as one form of evidence when evaluating whether the applicant is well positioned to advance the proposed endeavor.

An independent expert may also explain the broader implications of specialized work.

Institutional Support Letters Are Different

An NIW institutional support letter may come from the applicant’s employer or research institution and explain:

• future research plans;
• laboratory resources;
• funding;
• collaborations;
• the applicant’s position;
• ongoing projects; and
• the institution’s interest in the future endeavor.

Its value does not depend on independence because it serves a different evidentiary purpose.

Government Letters

A government official or scientist may be independent, dependent or somewhere between those categories depending on the relationship.

The important question is what the writer knows and what the letter establishes.

Is a Former Collaborator Independent?

Usually the relationship should still be disclosed.

Ending a collaboration does not erase the fact that the writer obtained knowledge through direct work with the applicant.

Is a Coauthor Independent?

A coauthor should generally not be described as completely independent regarding the coauthored work.

The coauthor can still provide valuable first-hand testimony.

Is Someone Who Cited You Independent?

A researcher who independently discovered and cited the applicant’s work may provide strong independent testimony, particularly if there was no later close collaboration.

The relationship should be described accurately if the researchers subsequently worked together.

Is a Conference Contact Independent?

Possibly.

The petition should focus on the actual professional relationship and how the writer became familiar with the applicant’s work.

Is a Friend Independent?

A personal relationship may affect how USCIS views the objectivity of testimony.

Professional evidence should generally focus on writers who possess meaningful subject-matter knowledge and a credible basis for evaluating the work.

Do Not Manufacture Independence

A petition should not conceal collaboration, supervision or other relationships in an attempt to make a letter appear more independent.

Accuracy is more important than the label.

How Many Independent Letters Are Needed?

There is no fixed number.

The appropriate mix depends on the case.

Review how many recommendation letters are needed.

A Balanced Letter Strategy

For a research petition, a useful combination might include:

• a PI explaining the applicant’s personal scientific contribution;
• a coauthor explaining the applicant’s role in an important publication;
• an independent scientist who cited the research;
• an independent institution that adopted the work; and
• a government or industry expert addressing broader importance.

The exact combination should be driven by the evidence.

Objective Evidence Remains Important

Whether a letter is independent or dependent, factual claims should be corroborated when documentation exists.

Examples include:

• citation records;
• publications;
• patents;
• licenses;
• research grants;
• contracts;
• clinical records;
• technical implementation;
• software usage; and
• government documents.

Common Independent-Letter Problems

• claiming a coauthor is independent;
• using writers who first learned of the applicant solely from an immigration packet;
• failing to explain how the expert knows the research;
• using independence as a substitute for substantive knowledge;
• submitting only independent letters and no one who can explain the applicant’s personal contribution;
• hiding professional relationships;
• using nearly identical letters; and
• relying on letters instead of objective evidence.

Choose Writers for What They Can Prove

Independent and dependent letters are not competing categories. A supervisor may best establish what the applicant personally accomplished, while an independent expert may best demonstrate how that work affected the broader field.
