A Request for Evidence, or RFE, is not a final adjudication outcome but rather a more demanding stage of review in the adjudication process. In employment-based immigrant 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 filing is evaluated under heightened scrutiny and must remain strategically positioned, internally consistent, and well-supported to ultimately secure approval.

The following success stories highlight nine approvals achieved after RFE review, including three EB-1A approvals, five NIW approvals, and one O-1A approval. These cases reflect varied scholarly profiles, procedural transfers between service centers, extended adjudication timelines, and filings that proceeded with limited supporting documentation, demonstrating that approval remains achievable even after intensified scrutiny and evolving adjudicative circumstances.

Cases With Inherent Challenges

Procedural Transfers Between Service Centers

Several petitions underwent procedural transfers between the Nebraska Service Center and the Texas Service Center during adjudication. Such movement adds complexity because the petition must remain internally consistent and persuasive while being reviewed across different adjudicative environments and officer perspectives.

Limited Supporting Documentation

Some approvals proceeded without recommendation letters or testimonial letters despite receiving RFEs during adjudication. In these cases, the petitions relied more heavily on the applicants’ objective scholarly records, professional consistency, and the overall coherence of the evidentiary presentation.

Extended Adjudication Timelines and Varied Processing Paths

The approvals also reflected differing procedural paths, including upfront premium processing filings, premium processing upgrades during adjudication, and at least one petition that remained pending for well over a year without premium processing before approval was secured. These varied timelines required the filings to maintain evidentiary strength and consistency throughout prolonged review periods.
