 Megan Elman, Esq. 
 Immigrant Justice Corps - Justice Fellow 

Before law school, Megan worked with noncitizen survivors of domestic violence and sexual assault in Raleigh, North Carolina on humanitarian immigration petitions.

She believes that no noncitizen, regardless of criminal history, deserves to be deported. As an IJC fellow, she will be working in removal defense and post final order relief at IJC’s Long Island Project.
 Geovanni Gutierrez-Vivar  
 Immigrant Justice Corps - Community Fellow 


Once an undocumented immigrant, Geovanni understands the mental and emotional struggle of integrating into a new country without any resources.

That same year, he also provided monthly legal services for constituents of Senator Jesse Hamilton at his Brooklyn office. His second placement was at the Queens Public Library.

 Mayra Interiano
