A Request for Evidence (RFE) represents one of the more demanding stages of adjudication in the employment-based immigration process. Once USCIS issues an RFE, the petition undergoes additional scrutiny, and the adjudicating officer may request further documentation or clarification 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 issues raised during review.

The following success stories highlight 13 approvals secured after RFE review. These approvals include 2 EB-1A petitions, 10 NIW petitions, and 1 O-1A petition. Several cases involved circumstances that added complexity to adjudication, including related adverse petition histories, multiple service center transfers, petitions with limited or no supporting letters, and applicants residing outside the United States.

Cases With Inherent Challenges

Related Adverse Petition History

One EB-1A approval after an RFE involved an applicant whose two related NIW petitions both received RFEs and were subsequently denied. Such petition histories can add complexity because each new filing must independently establish eligibility under its applicable legal standard while presenting a clear, consistent, and sufficiently supported evidentiary record.

Multiple Service Center Transfers

Several petitions underwent multiple service center transfers before final adjudication, moving between the Nebraska Service Center and the Texas Service Center. Such procedural movement can add complexity because the evidentiary record must remain logically structured, internally consistent, and persuasive throughout review by different service center operations.

Limited or No Supporting Letters

Several petitions proceeded without recommendation or testimonial letters, while others relied on a limited number of supporting letters. In these circumstances, the evidentiary record relied more heavily on objective indicators such as academic credentials, publication records, citation impact, and professional or research experience to document the applicants’ qualifications.

Applicants Residing Outside the United States

Two approvals involved applicants residing outside the United States at the time of adjudication. Such circumstances can add another consideration to the overall case context because the applicants’ qualifications, professional backgrounds, and supporting evidence must be presented clearly and consistently regardless of their current place of residence.
