Fleeing violence in his native Colombia, Felipe Salazar traveled to Miami in 2001 with his family on a visitor visa, hoping to get asylum, which was denied. This denial left him undocumented.  

Still, Salazar earned both bachelor's and master's degrees in engineering from the Georgia Institute of Technology in Atlanta. But because he couldn't work legally in the US, Salazar didn't go on interviews or participate in internships like his classmates. He traveled everywhere by car, fearing airports because they might ask for his documentation.
