Diane Cohen Haggiag

Diane joins Hammond Neal Moore as the managing attorney of our Los Angeles office.  Prior to joining the firm, Diane operated her own immigration law practice where she helped small businesses and individuals with their immigrant and non-immigrant visa applications.  She has managed a wide variety of cases in the following categories: E2, F1, J1, H1B, I1, L1, O1, EB1, EB3, as well as family-based adjustment of status and naturalizations.

Born and raised in France, Diane originally came to the U.S. as a law student.  After law school, Diane worked at corporate international law firms in New York and Los Angeles.  Diane’s immigration pro bono work at these firms along with her own navigating through multiple visa categories led her to focus on this area of law.  During her career, Diane acted as General Counsel of a French fashion company.  This experience proved indispensable to better understand her corporate clients’ needs, manage a team and appreciate the business implications of legal decisions.  During her tenure there, she was also providing immigration advice to potential French immigrants.

Diane enjoys practicing immigration law because she understands her clients’ fears, manages their expectations and advocates for them to help them achieve their dreams.  Through immigration law, Diane is able to apply her knowledge of both of the world’s major legal systems: when she advises her European clients, she particularly enjoys explaining the U.S. legal concepts that they’re familiar with only through TV shows and that they’re highly afraid of.  She loves the international dimension of this area of law and meeting clients from all over the world.

In her free time, Diane enjoys traveling, biking, skiing (the beauty of LA is that you can ski in the morning and go to the beach in the afternoon), and ever since moving to LA, her favorite hobby has become hiking the Malibu trails, where you can burn calories, suntan and admire gorgeous views all at once!
