A Request for Evidence (RFE) represents one of the more demanding stages of adjudication in the employment-based immigration process. When USCIS issues an RFE, a petition undergoes additional scrutiny, and further evidence or clarification may be requested regarding the applicant’s qualifications and eligibility under the applicable immigration standard. Successfully navigating this stage requires an evidentiary record that remains organized, internally consistent, and directly responsive to the concerns raised during review.

The following success stories highlight 24 approvals after RFE review, consisting of 7 EB-1A approvals, 16 NIW approvals, and 1 O-1A approval. Several cases presented circumstances that added complexity to adjudication, including prior petition denials followed by refiling, multiple service center transfers, applicants residing outside the United States, a non-STEM academic background, relatively modest scholarly records, and petitions initially filed without recommendation or testimonial letters.

Cases With Inherent Challenges

Related Adverse Adjudication Histories

Three approvals involved applicants with prior adverse adjudication histories, including earlier petitions that received RFEs and were subsequently denied. These applicants ultimately secured approval through refiled petitions, with some encountering additional RFEs during the subsequent adjudication process. Such circumstances added complexity because the new petitions needed to independently establish eligibility under the applicable immigration standards while addressing the challenges associated with earlier unfavorable outcomes.

Multiple Service Center Transfers

Several petitions underwent multiple transfers between the Nebraska Service Center and the Texas Service Center during adjudication. Such procedural movement can add administrative complexity because the evidentiary record must remain clearly organized and internally consistent throughout review across different service center operations.

Applicants Residing Outside the United States

Three approvals involved applicants residing outside the United States at the time of adjudication. These cases demonstrate that residence abroad does not necessarily prevent successful adjudication, provided that the petitions establish eligibility under the applicable immigration standards.
