Antonio Massa Viana, Esq.

Managing Attorney

Antonio is passionate about immigration law, civil rights, and constitutional issues, as well as about the clients he represents. He founded Massa Viana Law with the goal of creating a firm guided by the principles of excellency in advocacy, mutual respect, and most importantly, of service.

An immigrant himself who first moved to the United States when he was 12 years old, Antonio tackled the immigration system first in his own personal life. He discovered that many times, in order to succeed, you need to push the envelope and not give up, despite the odds. That vision is employed daily in his firm, where attorneys and staff are encouraged to seek creative legal solutions for difficult problems, even when the answers are not readily apparent.

This never-give-up attitude allowed Antonio to become the first known undocumented immigrant attorney in Massachusetts. He attended Roger Williams University School of Law, where he was the first Latino Editor-in-Chief of the RWU Law Review, as well as winner of the Esther Clark and National Religious Freedom moot court competitions; he sat for the bar exam in both Rhode Island and Massachusetts. Rhode Island would postpone his bar admission until he became a legal resident, but Massachusetts swore him despite his lack of legal status. Antonio started practicing immediately in immigration removal defense.

Antonio, together with his team, have helped hundreds of people—from those seeking refuge within our borders, to victims of violence and crimes, to those looking to once again be reunited with their loved ones—achieve their dreams of legal residency and citizenship.


A Commitment to Public Service and Social Justice


Over the years, Antonio learned he works best when serving others, something that is reflected on his and his firm’s commitment to public service and a more just society; that is why his firm has performed hundreds of hours of pro bono and community work.

This commitment has been there since before becoming a licensed attorney. During his college years, when working as a young journalist in Newark, NJ, Antonio organized legal clinics in partnership with local churches and attorneys in order to serve the city’s booming immigrant population.

He continued that work after moving to Massachusetts through Projeto Nos Votamos, an organization he founded to helped hundreds of immigrants file for citizenship and register to vote at no cost. Antonio also worked for the Brazilian Worker Center as a community organizer and worker’s rights advocate.

During law school, Antonio spent his summers at Catholic Social Services, working with low-income families, and, after graduating, went on to work as a legal consultant for the Massachusetts Refugee and Advocacy (MIRA) Coalition before leaving to open his own practice. He continues to volunteer countless hours to non-profit programs and private clients.

Antonio currently serves in the Board of Directors of the Massachusetts American Civil Liberties Union, the Brazilian American Center (BRACE) and of the Massachusetts Alliance of Portuguese Speakers (MAPS). He is a member of the American Bar Association and the American Immigration Lawyers Association.
