About me


I am the founder and owner of the Law Office of Sidney Collier, PLC, and have 10 years of experience working exclusively in the area of U.S. immigration and nationality law.  


My primary focus is employment-based immigration matters.  I have successfully assisted clients with H, L, and O temporary visas, and permanent residence matters including Extraordinary Ability, Outstanding Researcher, Multinational Executive/Manager, and PERM labor certification cases.  I have also worked with employers on I-9 and H-1B compliance issues.  I have proudly worked with all types of businesses, from small start-ups to large, multinational corporations, and worked with clients in the hospitality, international business, scientific research, engineering, technology, accounting and marketing sectors, and college and university settings, among others.   


I also focus on assisting clients with all facets of family-based matters including marriage-based petitions, and have a special affinity for naturalization cases.  I am also passionate about women’s issues, including VAWA and gender based asylum claims.  


I enjoy the challenge of staying informed about the rapidly evolving immigration laws and procedures, so I can best advise my clients, and eliminate guesswork from immigration filings.  


Prior to moving to Vermont with my family, I worked in high-volume law firms in both Washington, D.C. and Philadelphia, Pennsylvania.  I attended the American University’s Washington College of Law in Washington, D.C. (cum laude) and The George Washington University in Washington, D.C., where I majored in International Affairs, with a concentration in Latin America and a minor in Spanish.


I am a member of the American Immigration Lawyers Association, am the Chair of the Immigration Law Section of the Vermont Bar Association, and am the Secretary of the Washington County Bar Association.  I am an active member with the state bar of Vermont.
