EB-2 NIW Approval for Chemical Engineer from Ecuador Ecuador Chemical EngineerColombo & Hurd secured approval of an EB-2 National Interest Waiver (NIW) petition for a chemical engineer from Ecuador who specializes in pipeline integrity and corrosion assessment. The petition was approved after a Request for Evidence (RFE) response demonstrated the national importance of strengthening pipeline safety in the U.S. oil and gas industry. The United States depends on a vast network of oil and gas pipelines to move energy across the country. When these pipelines fail, they can cause environmental damage, disrupt supply, and lead to significant economic losses. Internal pipeline corrosion is a major contributor to these failures, which makes prevention and monitoring critical. Our client has built his career around this challenge. His proposed endeavor focuses on improving how companies detect and prevent corrosion in pipelines. His work supports safer operations, better resource management, and fewer environmental risks. This case study explains how Colombo & Hurd structured the petition and responded to the RFE to secure approval. The initial petition was led by Senior Attorney Allison McVey, with the RFE response strategy directed by Senior Attorney Nizar Kafrouni. Evaluate my Profile Client ProfileA Career Built on Pipeline Safety and Industrial SustainabilityEB-2 NIW VisaOur client holds a Bachelor’s Degree in Chemical Engineering and a Master of Business Administration (MBA), making him an expert in both the technical and operational sides of pipeline safety. His career has focused on the oil and gas sector, where he has worked across production, health and safety, chemical treatment, and transportation. In these roles, he developed and implemented corrosion assessment programs, designed pipeline integrity protocols, and guided operational teams through critical repairs. His work centers around preventing internal pipeline corrosion, a major cause of pipeline failures in the oil and gas industry. In the United States, he intends to apply this expertise to develop and implement advanced corrosion assessment and pipeline integrity strategies for the country’s oil and gas industry, helping reduce safety risks and environmental damage tied to pipeline failures. The Challenge Demonstrating National Importance and a Concrete Path Forward After the initial petition was filed, USCIS issued an RFE, requesting additional information on the substantial merit and national importance of the proposed endeavor. The RFE also questioned whether the client was well positioned to advance the endeavor and whether it would benefit the United States. Strategic Response Reframing the National Impact and Establishing a Concrete Plan The RFE response reinforced the petition’s core argument: that the client’s work addresses a clear national priority and that there is a concrete plan to deliver it in the United States. The response added further context on how the proposed endeavor extends beyond individual projects to meet broader needs across the U.S. oil and gas industry. It also demonstrated how the model plan, together with documented U.S. demand for the client’s expertise, establishes a clear path forward. As Attorney Kafrouni explained: “The strength of this response was in showing how each piece of evidence connects to the others. The endeavor is concrete, the plan to execute it is clear, and there is documented U.S. interest in this work.” The Result EB-2 NIW Approval After Comprehensive RFE Response USCIS approved the EB-2 NIW petition following the RFE response. With this approval, the client can move toward advancing his work in corrosion assessment and pipeline integrity in the United States, contributing to industrial process safety and environmental stewardship in the oil and gas sector. Why This Case Succeeded Connecting Specialized Expertise to National Priorities This case succeeded because the client’s work addresses a clear need in the United States. Corrosion assessment and pipeline integrity are not abstract concerns; they have direct consequences for communities, the environment, and the economy. The connection between his work and real-world impact was clearly explained. The other key factor was the diversity of the evidence. Independent letters of recommendation, supporting documentation, and letters of interest from U.S. companies each contributed something different: technical credibility, policy context, and proof of real demand. No single piece of evidence carried the case alone. The combination is what made the petition difficult to question on any one front.
