Edwin Sierra is the Head of Operations at Z&W Law Firm PLLC, where he oversees legal strategy, case management, and administrative operations across both U.S. and international teams. With over a decade of experience in immigration law and legal business development, Edwin brings a uniquely integrated perspective to client representation and firm leadership.
He holds an LL.M. in American General Law from the Benjamin N. Cardozo School of Law in New York City, where he focused on advanced U.S. legal principles. His legal career began in Colombia after earning his J.D. from the University of Medellín in 2015. These dual foundations—rooted in both civil and common law systems—enable him to serve a diverse client base with exceptional cultural and legal fluency.
Edwin concentrates on family-based and employment-based immigration, humanitarian relief, and consular matters. He has extensive experience with I-130 family petitions, I-360 applications such as VAWA and SIJS, U and T visas, adjustment of status, advance parole, employment authorization, naturalization, and inadmissibility waivers (I-601, I-601A, I-212). He also assists clients in complex interactions with multiple agencies under the Department of Homeland Security (including USCIS, ICE, CBP, the Ombudsman’s Office, and TSA), the Department of Labor, the National Visa Center, local police departments, district attorney offices, and U.S. consulates worldwide.
Having navigated the immigration system himself, Edwin brings both technical precision and deep empathy to his work—qualities that have contributed to an exceptional approval rate across hundreds of immigration cases. He is particularly known for his advocacy on behalf of survivors of violence, labor trafficking, and other vulnerable populations.
A bilingual legal professional committed to equity and access, Edwin continues to lead with integrity, operational excellence, and a heartfelt commitment to immigrant communities.
