20 I-140 Approvals After RFE on October 15, 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 20 I-140 approvals involving RFE review or adverse petition histories, consisting of 3 EB-1A approvals and 17 NIW approvals. Several cases presented circumstances that added complexity to adjudication, including previously denied petitions, multiple service center transfers, applicants in non-STEM fields, an applicant without an advanced degree, and petitions that proceeded without supporting letters.
Cases With Inherent Challenges
Adverse Petition Histories
Three applicants had petition histories involving RFEs, denials, or unsuccessful appeals. These circumstances can add complexity to adjudication because an adverse outcome associated with one petition does not automatically determine eligibility in another. Each petition must independently establish that the applicant satisfies the applicable immigration requirements, supported by an evidentiary record addressing the relevant legal standards regardless of the outcomes associated with other petitions.
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.
Petitions Proceeding Without Supporting Letters
Several petitions initially proceeded without recommendation or testimonial letters. While some applicants submitted additional supporting letters in response to RFEs, four petitions secured approval without any recommendation or testimonial letters throughout the entire adjudication process. These cases illustrate how eligibility may be established through the overall evidentiary record, including documented scholarly achievements, professional qualifications, and other relevant evidence.

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.
