An Established Boston Firm Representing Clients Throughout New England And Beyond

Among immigration law firms in Boston, few are as established and have been a greater legal ally for our foreign nationals and the American companies that wish to employ them than O'Neil & Hauser P.C.

Our firm's roots go back several decades, when under the management of attorney Joseph F. O'Neil we represented large numbers of immigrants resettling in the Greater Boston area. As the years have passed and the face of America's immigrants has changed, we have evolved to ensure we meet the needs of all our clients, regardless of whether they need straightforward visa application services, more nuanced assistance with employment-related visas or aggressive representation in removal proceedings.

Greater Boston and New England have become a global center of medical research, technology and other STEM fields. Our firm has evolved to offer undergraduate and post-graduate students as well as workers from around the world the immigration help they need to come to the United States to realize their professional goals. In addition to handling traditional work visas and green cards, our Boston immigration lawyers have represented many people seeking to invest in the U.S. and gain residency through their investments.

Now, under managing partner Lesley Hauser, we provide a full range of immigration services to individuals and families throughout Massachusetts and New England. Our attorneys have decades of combined experience and are members of the American Immigration Lawyers Association. In addition to our attorneys themselves, many of whom speak additional languages, we offer translation services in many languages, including:

  • Spanish
  • Portuguese
  • Mandarin
  • Cantonese
  • Greek
  • French
  • Italian
  • Arabic

Our advocacy goes far beyond the work we do for clients directly. Our Boston immigration attorneys are also actively involved in the greater community, presenting to community groups throughout Greater Boston about aspects of the immigration system and giving people practical information to make their lives easier.

We have regularly spoken before numerous government agencies, nonprofit organizations and community groups on immigration issues; these include:

  • Consulates of El Salvador and Guatemala
  • Human Resource Professionals conference
  • Assistant District Attorneys of Middlesex and Suffolk County
  • Portuguese and Spanish TV programs and radio broadcasts
  • Other religious groups
