My Immigration Story:

I am a second generation Irish American and dual US-Irish citizen. My forebears on both sides were Irish. My mother’s parents left County Cork for New York in 1900, seeking to escape the grinding rural poverty they had always known. My grandfather worked as a longshoreman on the Hudson River docks, while my grandmother had primarily responsibility for the large family living in what was then the working class immigrant neighborhood of Greenwich Village. When they were more established they bought a house in Brooklyn, where my mom and dad met and raised our clan. (I am one of 11 children.) Growing up in the ethnic and racial diversity of Brooklyn, it was obvious to me that immigration was a great benefit both to the individuals and families directly involved but also to the larger community, which was enriched and strengthened by the hard work, talents, and diverse perspectives (not to mention food and music) of immigrants. When I was a young lawyer I lived several years in Chad, Africa, as a Peace Corps Volunteer. That incredible experience profoundly influenced me and confirmed my desire to dedicate my career to working with people who – seeking protection from persecution or desiring a better future for themselves and their children – take the courageous decision to emigrate to the United States.
