About Ozlem Barnard

Principal, Barnard Legal PLLC | Federal District Court Litigation and Mediation

As a Trial Attorney at the Department of Justice's Office of Immigration Litigation, Oz Barnard handled complex cases in federal district and appellate courts nationwide, addressing issues of first impression in federal jurisdiction, statutory interpretation, administrative law, and constitutional law.

Her caseload included mandamus and APA challenges to citizenship, permanent residency, and visa delays, habeas petitions, and class-action challenges to adjudication procedures. She also represented federal agencies in settlement conferences, applying conflict-resolution and mediation skills.

Before DOJ, Oz served as a Trial Attorney at ICE within DHS, representing the agency across the Fourth, Ninth, and Eleventh Circuits, then advised ICE and DHS Headquarters on high-profile cases and policy matters. She trained federal attorneys, ICE, USCIS, and CBP officers, and immigration judges throughout her government career.

With 19 years of federal immigration litigation experience, Oz now trains and mentors immigration attorneys on mandamus and APA litigation, drawing on her experience on both sides of these cases at DHS and DOJ.
