CHICAGO – The day Margarita Del Pilar Fitzpatrick applied for an Illinois driver’s license upended her life. When a clerk offered to register her to vote in 2005, the Peruvian citizen mistakenly accepted, leading to long legal battles and eventually deportation. A decade and a half later, she struggles to find work at 52, is nearly homeless and hasn’t seen two of her three American citizen daughters in years because of a secretary of state’s office mishap. “It has derailed our lives,” she said in a phone interview from Lima.
