Success Stories After RFE: 9 I-140 Approvals on February 27, 2026

A Request for Evidence (RFE) does not signify the end of a case. The following nine success stories represent I-140 petitions that were initially issued an RFE but were ultimately approved. These outcomes reflect our firm’s experience addressing complex adjudication issues, including cases involving heightened scrutiny and inherent challenges.


Cases With Inherent Challenges

Many of the approvals in this batch involved profiles that commonly receive additional scrutiny from USCIS. Our team has substantial experience preparing well-documented petitions for clients in these circumstances.

EB-1A Without a Ph.D.

Two of the three EB-1A approvals in this batch were for applicants holding only a master’s degree. While EB-1A does not require a Ph.D., applicants without a doctoral degree may face heightened scrutiny. Through careful legal argumentation and comprehensive documentation of extraordinary ability, we have successfully represented numerous applicants without doctoral degrees in securing EB-1A approval.

Filing Without an Advanced Degree

One of the most common strategic considerations clients face is whether to wait until completion of a master’s or Ph.D. degree before filing. Waiting may provide a straightforward path to meeting the EB-2 advanced degree requirement, but it can also delay filing by years.

For clients who elect not to wait, we file under either the bachelor’s degree plus five years of progressive experience pathway or the exceptional ability classification. These classifications are frequently scrutinized and often result in RFEs. In this batch, Case #5 is a representative example: the client filed as a Ph.D. student without an advanced degree, claimed eligibility under both exceptional ability and the bachelor’s plus five years pathway, received an RFE, and was ultimately approved.

Filing From Outside the United States

Case #8 involved an applicant residing in Vietnam at the time of filing. Filing from abroad introduces additional complexity, as adjudicators may closely examine the applicant’s proposed U.S.-based endeavor and future plans. Our team has extensive experience preparing persuasive NIW petitions for applicants residing outside the United States that satisfy all three prongs of the NIW framework.

Non-STEM and Non-Traditional Research Profiles

Several approvals in this batch involved non-STEM designated fields and non-traditional research classifications, both of which may face additional scrutiny. Case #7, a neuroscience postdoctoral scholar, was approved in a non-STEM designated field with 38 citations. Cases #8 and #9 involved non-traditional research profiles with low citation counts (14 and 23 respectively) and were approved after RFE.

Client names have been omitted to protect confidentiality. Each summary includes the applicant’s category, field, country of birth, current residence, credentials, letters submitted, service center, and premium processing strategy.
