PLI Program #: 210053

Holly Cooper, Co-director of the Immigration Law Clinic, has extensive litigation experience defending the rights of immigrants and is a nationally recognized expert on immigration detention issues and on the immigration consequences of criminal convictions.

Cooper is a graduate of UC Davis School of Law, where she was on the Board of the King Hall Legal Foundation and an active member of the National Lawyers Guild. She received her B.A. degree in Political Science from the University of California, San Diego. As an undergraduate, she also studied Political Science and Economics at the University of Padua in Italy. She speaks, reads and writes in both Spanish and Italian.

After law school, Cooper worked for Reed Smith LLP (formerly Crosby, Heafey Roach & May LLP), The Law Offices of Fellom & Solorio, and the Florence Immigrant & Refugee Rights Project. As the Senior Staff Attorney at the Florence Project, Cooper initiated the Detained Immigrant Children’s Rights Project, provided representation and pro se assistance for adult detainees, and mentored pro bono attorneys. She currently serves on the UC Haiti Initiative’s Steering Committee and is on the Advisory Board for the Gifford Center for Population Studies.

Cooper joined the School of Law faculty in 2006. In the Immigration Law Clinic, she focuses on advocating for the rights of detained immigrants. In 2011, she was the recipient of the King Hall Legal Foundation’s Outstanding Alumni Award and the Carol Weiss King award from the National Lawyers Guild.

Cooper also trains lawyers on a national level and regularly speaks at academic conferences. She provides expert legal advice to public defenders and was the American Immigration Lawyers Association’s Liaison to the Office of the Chief Immigration Judge for two years. In the international domain, Cooper has worked on human rights issues in Haiti and has volunteered on multiple human rights delegations to Haiti since the earthquake.

The Law Offices of Matthew H. Green focuses on the aggressive defense of immigrants. A native of Arizona, Mr. Green understands the difficulties that immigrants and families of immigrants face when a loved one is charged with a crime. He knows how frightening it can be for someone who has been arrested by the Immigration and Customs Enforcement Agency ("ICE"), and placed into removal, or deportation, proceedings. Often times, an immigrant faces deportation only after he is found guilty of committing a crime. For this reason, Mr. Green's law practice focuses on effective criminal defense of immigrants charged with crimes so that they may avoid removal (deportation) charges altogether.

In addition to criminal defense, Mr. Green's law firm also emphasizes removal (deportation) defense of those immigrants who must fight deportation. The majority of Mr. Green's clients are placed in detention in Florence, Arizona, or Eloy, Arizona. Our law firm represents these individuals in the Eloy and Florence Immigration Courts. Mr. Green represents immigrants with cases in the Tucson Immigration Court, and the law firm serves those people who are arrested in Nogales, Arizona, and Douglas, Arizona.

Mr. Green also represents clients charged with felonies in the U.S. District Court in Tucson, Arizona. At any given time, Mr. Green defends a variety of clients who have been charged with crimes like Illegal Reentry, Alien Smuggling or Transportation, and Transportation of Drugs. The majority of these clients are undocumented immigrants. In the United States of America, even undocumented immigrants enjoy the same rights as U.S. citizens. Mr. Green fights to protect his clients' rights, in their criminal cases and in their immigration cases.

For those immigrants who have been living in Arizona or other parts of the United States, the Law Offices of Matthew H. Green helps these people and their families gain legal immigration status. If you are an undocumented immigrant with family members who are United States citizens, or even Legal Permanent Residents, then we may be able to help you obtain a visa or a "green card." At the Law Offices of Matthew H. Green, our staff will help you identify all possible alternatives for legally coming to, and remaining in, the United States of America.

Mr. Green and his staff are fluent in Spanish. The majority of our immigration clients speak Spanish, and we are happy to answer questions from Spanish-speaking clients and their family members.
