Founding Attorney

Owner Ellen Sullivan has practiced immigration law for 15 years during four Presidential administrations. Licensed in Massachusetts, Ellen practices immigration law nationwide and at U.S. embassies and consulates around the world.  Since 2005, Ellen has been honored to partner with hundreds of immigrants to resolve their U.S. immigration cases. Ellen has developed an expertise in a variety of immigration case law for a diverse range of clients, ranging from simple consultations to complex litigation in federal immigration court.

Ellen is committed to advocating for all kinds of families in her practice and takes great joy in helping her clients realize their dreams and goals. Since the summer of 2013 when the U.S. Supreme Court overruled the Defense of Marriage Act, all immigration benefits are available regardless of whether a same-sex marriage created the qualifying relationship. Ellen considers it a privilege to advise same-sex families on marriage-based immigration matters.

Prior to founding Cambridge Immigration Law, Ellen was a partner at two law firms and worked at non-profit organizations including the Victim Rights Law Center and Centro Presente. She has worked in the United States, Spain, and Argentina. She is fluent in Spanish and is learning Portuguese. 

While in law school at Northeastern University School of Law, she worked at the U.S. Attorney’s Office, the Center for Justice and International Law in Buenos Aires, and Greater Boston Legal Services. Ellen earned her undergraduate degree from Dartmouth College. She is a member of the American Immigration Lawyers Association (AILA) and Secretary on the Executive Board for the New England chapter of AILA.
