EB1B RFE: Separate the Researcher’s Evidence From the Employer Requirements
An EB1B RFE may question the researcher’s international recognition, the three years of qualifying experience, the offered position or the petitioning employer. A strong response identifies which part of the EB1B structure USCIS is challenging before deciding what additional evidence is needed.
Four Part RFE Audit
Diagnose the RFE Before Collecting More Evidence
International recognition
Did USCIS conclude that the evidence as a whole failed to show the researcher is internationally recognized as outstanding?
Research experience
Did USCIS question the three years, dates, academic area or underlying duties?
Employer and position
Did USCIS question permanence, private employer requirements or the qualifying offer?
Common EB1B RFE Issues
What USCIS May Question
Original Contributions Research contribution shown but significance
or recognition insufficiently explained.
Judging Review invitations submitted without
adequate completion evidence.
Authorship Publications submitted but broader
international recognition remains disputed.
Final Merits Two or more criteria met but total record
considered insufficient for international recognition.
Three Years Experience Dates, duties or graduate research
do not clearly satisfy the requirement.
Permanent Position Appointment appears temporary
or limited in duration.
Private Employer Research staffing or documented accomplishments
not sufficiently established.
Offer of Employment Offer does not clearly satisfy
the applicable EB1B structure.
Response Matrix
Match the RFE Issue to the Correct Evidence
USCIS Concern Response Focus Potential Evidence
Three years experience Dates and qualifying research duties Detailed employer letters,
appointment records and project evidence
Permanent position Nature and expected duration of employment Offer letter, employer declaration,
funding history and renewal evidence
Private employer Research staffing and academic accomplishments Organization chart, researcher roster,
publications, patents and research programs
Original contributions Significance and recognition of the research Citations, adoption, implementation
and independent expert evidence
Final merits International recognition as outstanding Totality of evidence, comparative context
and independent recognition
Response Workflow
Build the EB1B RFE Response in Six Steps
01 Extract the findings
Identify every accepted and disputed issue.
02 Separate structure from recognition
Do not mix employer defects with researcher evidence.
03 Audit existing exhibits
Determine what already answers each USCIS concern.
04 Obtain targeted documents
Fill the actual evidentiary gaps.
05 Explain the connection
State what each important exhibit proves.
06 Rebuild international recognition
Explain the complete research record, not merely the number of criteria met.
Common Response Failure
Do Not Treat EB1B as EB1A With an Employer
Weak
Focus only on publications, citations and letters.
A strong researcher record cannot cure a failure to establish the qualifying employer, research position or required experience.
Stronger
Prove every part of the EB1B structure.
Organize the response around international recognition, research experience, the employer and the qualifying position.

Common Questions
EB1B RFE FAQ
Does meeting two EB1B criteria guarantee approval?
No. USCIS evaluates the evidence together to determine whether the beneficiary is internationally recognized as outstanding in the academic field.
Can USCIS question both the employer and the researcher?
Yes. The structural requirements and the researcher’s international recognition are separate components of EB1B eligibility.
Should the employer provide new evidence in an RFE response?
When the RFE questions the employer, position or experience requirements, targeted employer records may be essential.
Is EB1B easier than EB1A?
They use different legal structures and should be evaluated separately. EB1B also imposes employer, position and experience requirements that EB1A does not.
