4 I-140 Approvals After RFE on October 13, 2026
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 4 NIW I-140 approvals after RFE review. Several cases presented circumstances that added complexity to adjudication, including petitions filed in non-STEM fields, multiple service center transfers, applicants with relatively modest publication or citation records, and a petition that initially proceeded without supporting letters.
Cases With Inherent Challenges
Petitions Filed in Non-STEM Fields
Two approvals involved applicants in non-STEM fields, specifically Applied Microeconomics and Economics. These cases highlight the importance of establishing eligibility under the NIW framework through the significance of the proposed endeavor and the applicant's qualifications.
Multiple Service Center Transfers
Two petitions underwent multiple transfers between the Texas Service Center and the Nebraska 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.

The key to our success is the way in which we present supporting evidence and provide the highest quality petition letters. With over 69,000 I-140 EB-1 ( EB-1A Alien of Extraordinary Ability; EB-1B Outstanding Researcher or Professor), EB-2 NIW (National Interest Waiver) and O-1 approvals, our firm has acquired substantial information about USCIS decisions, which gives us significant advantage over firms that only handle a small number of cases.
Based on our close track of USCIS internal memoranda, AAO decisions, and judicial review decisions, we have unique insight into the USCIS adjudication trends. Not only do we apply this insight into our approaches to our clients' cases, but we also carefully review all RFEs (Requests for Evidence), NOIDs (Notices of Intent to Deny), approvals, and denials issued on our cases so that we can further increase our understanding of USCIS strategies and decision-making processes. With the insight, we are able to advise our clients on the best ways to proceed with their petitions.
While other petitioners and attorneys may still use templates to draft recommendation letters or petition letters, our clients' recommendation letters and petition letters are tailored to their individual credentials to best persuade a USCIS officer that our clients meet the requirements of the category they are applying under and therefore their petitions deserve to be approved. To provide the best EB-1 and EB-2 NIW services, our law firm only selects attorneys who have received their professional Juris Doctor degrees from the top law schools in the U.S. and who have garnered rigorous analytical skills through years of experience.
