A Request for Evidence, or RFE, is not a final adjudication outcome, but it reflects a more demanding stage of review in the adjudication process. In employment-based petitions, an RFE generally indicates that the adjudicating officer requires a clearer articulation of eligibility, a stronger evidentiary connection between the applicant’s accomplishments and the governing legal standard, or additional clarification regarding the applicant’s proposed work and broader impact. Once a petition enters this stage, the case is evaluated under heightened scrutiny and must remain internally consistent, strategically presented, and well-supported to secure approval.

The following success stories highlight five approvals achieved after RFE review, including one EB-1A approval, three NIW approvals, and one O-1A approval. These cases reflect varying evidentiary profiles, procedural movement between service centers, prior related petition scrutiny, and petitions proceeding with little or no supporting documentation, demonstrating that approval remains possible even after intensified review.

Cases With Inherent Challenges

Multiple Service Center Transfers During Adjudication

Several petitions experienced procedural transfers between the Nebraska Service Center and the Texas Service Center before approval was ultimately secured. Such movement increases adjudicative complexity because the petition must maintain consistency across different reviewing environments and officer perspectives throughout the adjudication process.

Varied Evidentiary Profiles

The cases reflected varied evidentiary profiles, including modest publication counts, limited supporting letters, and petitions with no supporting letters. These differences required each case to rely on a clear connection between the applicant’s objective record and the applicable legal standard.

Prior Related Petition Scrutiny

One O-1A approval involved an applicant whose related EB-1B petition had previously received an RFE and was ultimately approved. This prior RFE history adds adjudicative complexity because the applicant’s record had already undergone heightened review in another classification before the O-1A approval was secured.

EB-1A Approval After RFE (1)

#1: EB-1A in Materials Chemistry

This EB-1A approval involved a Process Engineer in industry, born in China and residing in the United States, who proposes to continue in the same role. Filed in Materials Chemistry, the petition received an RFE from Officer XM1313 before approval was ultimately secured.

The applicant held a STEM Ph.D. and presented a strong scholarly profile consisting of 20 publications and 504 citations, including recent peer-reviewed work published in 2025. The filing was supported by four recommendation letters and proceeded without testimonial letters.

The case was adjudicated through the Nebraska Service Center with a premium processing upgrade after filing.

NIW Approvals After RFE (3)

#2: NIW in Electrical Engineering

This NIW approval involved a Senior Transmission Planning Engineer, born in China and residing in the United States, who proposes to continue in the same role. Filed in Electrical Engineering, the petition received an RFE from Officer XM2375 before approval was ultimately achieved.

The applicant held a STEM Ph.D. and presented a credible scholarly record consisting of 14 publications and 160 citations, with the latest peer-reviewed publication appearing in 2023. The filing included two recommendation letters and no testimonial letters.

The petition was adjudicated at the Texas Service Center without premium processing and remained pending for 765 days before approval was secured.

#3: NIW in Materials Science and Engineering

This NIW approval involved a Ph.D. student, born in Taiwan and residing in the United States, who proposes to become a Postdoctoral Scholar. Filed in Materials Science and Engineering, the petition received an RFE from Officer XM0725 before approval was ultimately secured.

The applicant held a STEM bachelor’s degree and presented a developing but persuasive scholarly profile consisting of 13 publications and 334 citations, including recent peer-reviewed work published in 2025. The petition proceeded without any supporting letters.

The case experienced multiple procedural transfers, moving from the Nebraska Service Center to the Texas Service Center and later returning to the Nebraska Service Center with a premium processing upgrade.

Notable: This approval is notable for securing NIW approval after RFE review without recommendation or testimonial letters while navigating multiple service center transfers.

#4: NIW in Cell and Molecular Biology

This NIW approval involved a Postdoctoral Associate, born in Sri Lanka and residing in the United States, who proposes to continue in the same role. Filed in Cell and Molecular Biology, the petition received an RFE from the Nebraska Service Center before approval was ultimately achieved.

The applicant held a STEM Ph.D. and presented a focused scholarly profile consisting of 6 publications and 298 citations, with recent peer-reviewed work published in 2026. The petition proceeded without any supporting letters.

The adjudication involved procedural transfers from the Texas Service Center to the Nebraska Service Center and then back to the Texas Service Center, with a premium processing upgrade.

Notable: This approval is notable for achieving NIW approval after RFE review without recommendation or testimonial letters while undergoing multiple service center transfers.

O-1A Approval After RFE (1)

#5: O-1A in Pharmaceutical Science

This O-1A approval involved a Scientist II working in industry, born in China and residing in the United States, who proposes to continue in the same role. Filed in Pharmaceutical Science, the approval followed a prior EB-1B petition that received an RFE from Officer XM1333 and was subsequently approved, before the O-1A petition was ultimately secured.

The applicant held a STEM Ph.D. and presented a scholarly record consisting of 5 publications and 138 citations, including peer-reviewed work published as recently as 2024. The filing was supported by four recommendation letters and proceeded without testimonial letters.

The petition was adjudicated through the California Service Center utilizing upfront premium processing.

Notable: This approval is notable for achieving O-1A approval following a prior EB-1B petition that received an RFE and was approved.
