A Request for Evidence (RFE) represents one of the most demanding stages of adjudication in the employment-based immigration process. When USCIS issues an RFE, the petition enters a heightened level of review in which the adjudicating officer seeks additional clarification, stronger evidentiary support, or a more persuasive explanation connecting the applicant's accomplishments to the applicable immigration standard. Successfully navigating this stage requires a record that remains organized, internally consistent, and directly responsive to the concerns raised during adjudication.

The following success stories highlight 8 approvals secured after RFE review. These approvals include 7 NIW petitions and 1 O-1A petition. Several petitions underwent multiple service center transfers, one applicant remained outside the United States throughout adjudication, and one petition proceeded without recommendation or testimonial letters. Together, these approvals demonstrate that favorable outcomes remain achievable when the evidentiary record remains coherent, responsive, and aligned with the applicable legal standard.

Cases With Inherent Challenges

Multiple Service Center Transfers

Several petitions were transferred from the Nebraska Service Center to the Texas Service Center and then back to the Nebraska Service Center before final adjudication. Such procedural movement can introduce additional complexity because the evidentiary record must remain well-organized, internally consistent, and persuasive throughout the review by different adjudicators.

Limited or No Supporting Letters

One approval proceeded without either recommendation letters or testimonial letters, while several others relied on only a small number of supporting letters. In these cases, adjudication depended more heavily on objective evidence, including publication record, citation impact, recent scholarly contributions, and documented professional accomplishments.

Residence Outside the United States

One approval involved an applicant who remained outside the United States throughout adjudication. In such cases, the petition must still present a persuasive and well-documented record establishing the applicant's qualifications, current professional activities, and the anticipated value of the proposed work despite the applicant residing abroad.
