Immigration Counsel You Can Rely On — Since 1991

Antao & Chuang is a boutique federal immigration practice. Since 1991, we have counseled individuals, families, businesses, educational institutions, hospitals, and nonprofits on the full arc of U.S. immigration — from the first temporary visa to permanent residence (green card) and citizenship. We are based in Manhattan, and because immigration is federal law, we serve clients in every state.

Our work is built on direct attorney-client relationships. When you hire us, you work with an experienced attorney — not a paralegal, not a chatbot — from your first call to your last filing. We take your calls and answer your e-mails, we know your file, and we explain the law clearly. Contact us now.
