Recommendation Letters for Researchers

Recommendation letters are frequently submitted in EB1A, EB1B and EB2 National Interest Waiver petitions for researchers, scientists, professors and other academic professionals. They can help USCIS understand specialized research, the applicant’s personal contributions and why particular accomplishments matter within a technical field.

Recommendation letters are supporting evidence. There is no universal rule requiring a specific number of letters, and strong letters should be supported by objective evidence whenever possible.

What Can a Research Recommendation Letter Establish?

Depending on the immigration classification and the writer’s knowledge, a letter may help explain:

• the applicant’s personal role in collaborative research;
• the originality of a scientific or scholarly contribution;
• the significance of the contribution to the field;
• how independent researchers have used the applicant’s work;
• the applicant’s standing in a specialized research community;
• why a proposed NIW endeavor matters;
• why the applicant is well positioned to advance future research;
• the significance of citations, patents, grants or technology adoption; and
• the applicant’s responsibilities within an important research program.

Recommendation Letters and EB1A

EB1A does not contain a separate recommendation-letter criterion.

Letters can nevertheless provide important evidence concerning regulatory criteria and the final merits determination.

For researchers, expert letters are often used to explain:

• original contributions of major significance;
• leading or critical roles;
• the significance of judging or peer review;
• published research and citation evidence; and
• overall professional recognition.

Letters and EB1A Original Contributions

Detailed expert letters can help USCIS understand why a highly technical contribution matters to a specialized field.

A strong letter identifies the contribution precisely and explains its effect.

Examples may include:

• another laboratory adopted the applicant’s method;
• the research changed later experimental design;
• the applicant’s technology solved a recognized technical problem;
• a patented invention entered commercial use;
• clinical researchers relied on the applicant’s findings; or
• the contribution opened a new direction of research.

General statements that research is “groundbreaking” or “important” are less persuasive when the writer does not explain why.

Letters and EB1A Final Merits

At final merits, USCIS considers the complete record to determine whether the applicant has sustained national or international acclaim and is among the small percentage who have risen to the top of the field.

Letters can help place objective evidence into professional context, but they should not substitute for the evidence itself.

Recommendation Letters and EB1B

EB1B requires international recognition as outstanding in a specific academic area.

Recommendation letters may help explain:

• the applicant’s original scholarly or scientific contributions;
• international recognition;
• the importance of publications;
• citation influence;
• peer-review activity;
• research leadership; and
• the applicant’s standing in the academic field.

Recommendation Letters and NIW

NIW does not require recommendation letters, but support letters can be useful in explaining the proposed endeavor and whether the applicant is well positioned to advance it.

A letter may address:

• the research problem;
• the prospective impact of the endeavor;
• the applicant’s past record of success;
• technical qualifications;
• progress already made;
• available research resources;
• institutional support;
• government or industry interest; and
• future collaborations.

Who Should Write a Research Recommendation Letter?

The appropriate writer depends on what the letter is intended to prove.

Potential writers include:

• principal investigators;
• research supervisors;
• professors;
• collaborators;
• independent researchers;
• journal editors;
• government scientists;
• industry experts;
• technology users;
• institutional officials; and
• other professionals with meaningful knowledge of the applicant’s work.

Supervisor Letters

A supervisor may possess the strongest first-hand knowledge of the applicant’s personal contribution to a research project.

A supervisor can often explain:

• what problem the research group was addressing;
• what the applicant personally developed;
• why the applicant’s contribution was difficult or important;
• how the applicant’s work differed from ordinary assigned duties; and
• what results came from the applicant’s contribution.

Collaborator Letters

A collaborator can provide detailed testimony concerning work performed jointly with the applicant.

The letter should accurately disclose the relationship rather than describe the writer as independent.

Independent Expert Letters

An independent expert can be useful where the writer learned about the applicant through publications, citations, technology adoption, conference activity or professional reputation rather than through direct supervision.

Review independent versus dependent recommendation letters.

Independent Does Not Mean Unfamiliar

The strongest independent writer generally has a genuine professional basis for knowing the applicant’s work.

A researcher who cited or used the applicant’s work may be more persuasive than someone who first learned of the applicant only after being asked to review a curriculum vitae for an immigration letter.

Government Letters

Letters from government agencies or government researchers may be particularly useful when they provide specific information concerning:

• government-funded research;
• agency interest;
• national scientific priorities;
• government use of the work;
• critical technology;
• public health; or
• other governmental interests.

Letters From Technology Users

A researcher or company that actually implemented the applicant’s technology may provide strong evidence of practical impact.

The letter should explain what was used and what changed because of that use.

Letters From Journal Editors

An editor may provide direct evidence concerning:

• why the applicant was selected as a reviewer;
• completed peer reviews;
• editorial board responsibilities;
• specialized expertise; and
• the significance of repeated reviewing activity.

Letters Should Explain the Writer’s Basis of Knowledge

A persuasive letter normally tells USCIS how the writer knows the applicant or the applicant’s work.

Examples include:

• direct supervision;
• research collaboration;
• citation of the applicant’s publication;
• use of the applicant’s method;
• implementation of patented technology;
• conference interaction;
• editorial activity; or
• independent familiarity with the research.

Specific Facts Are Better Than Adjectives

Statements such as “Dr. Chen is brilliant” or “Professor Smith is internationally recognized” provide limited information by themselves.

A stronger letter identifies concrete facts.

For example, the writer might explain that:

• the writer’s laboratory changed its procedure after reading the applicant’s study;
• the applicant developed an algorithm later adopted by an independent team;
• a patented device was licensed and incorporated into a commercial product;
• the applicant’s findings were incorporated into a clinical protocol; or
• the applicant solved a technical problem that had limited prior research.

Objective Corroboration

Letters are stronger when their factual claims are supported independently.

Potential corroborating evidence includes:

• publications;
• citation records;
• patents;
• licenses;
• contracts;
• research grants;
• government records;
• clinical guidelines;
• software adoption;
• technical documentation; and
• media coverage.

Letters Should Not Become the Entire Case

A petition supported only by recommendation letters may be vulnerable where objective evidence should reasonably exist.

Letters are most effective when they interpret and explain a well-documented record.

Different Letters Should Serve Different Purposes

Submitting six letters that repeat the same facts may add little value.

A more effective group may include:

• one supervisor explaining the applicant’s personal contribution;
• one independent researcher explaining external adoption;
• one government or industry expert explaining broader importance;
• one institutional representative explaining future support; and
• another expert addressing a different significant accomplishment.

Do Not Hide Professional Relationships

A close collaborator can write an excellent letter.

The relationship should be described accurately so USCIS can evaluate the writer’s knowledge and perspective.

Avoid Template Language

Letters that use nearly identical wording may appear formulaic.

Each letter should reflect the writer’s own knowledge, experience and perspective.

Avoid Unsupported Legal Conclusions

Experts generally provide the greatest value when they explain professional facts rather than simply state that the applicant “meets the EB1A standard” or “deserves a national interest waiver.”

USCIS makes the legal determination.

How Long Should a Letter Be?

There is no required length.

A letter should be long enough to explain the relevant facts without repeating the applicant’s entire curriculum vitae.

Focused, detailed letters are generally more useful than lengthy letters filled with generic praise.

How Many Letters Are Needed?

There is no fixed USCIS number.

The proper number depends on the evidence and the distinct facts that knowledgeable writers can establish.

Review how many recommendation letters may be appropriate.

Common Recommendation Letter Problems

• using an arbitrary letter quota;
• submitting nearly identical letters;
• calling collaborators independent;
• failing to explain how the writer knows the work;
• using adjectives instead of facts;
• making unsupported claims of widespread impact;
• relying on letters instead of available objective evidence;
• asking every writer to discuss every immigration requirement; and
• focusing on the applicant’s character rather than professional evidence.
