Rumors about deportation raids started to circulate around the fields again, so Catalina Sanchez and her husband began to calculate the consequences of everything they did. Cirilo Perez, 36, had to go to work because the tomato crop was getting low, and he needed to pick as much as he could as fast as he could. Sanchez’s medical checkup would have to wait — going to a clinic was too risky. What they fretted most about was what to do with their daughter Miriam — a natural-born citizen in the third grade — who they worried would come home one day to an empty trailer. “When she leaves, I wonder if it will be the last time I see her,” Sanchez, 26, said on a recent evening. As President Trump moves to turn the full force of the federal government toward deporting undocumented immigrants, a newfound fear of the future has already cast a pall over the tomato farms and strawberry fields in the largely undocumented migrant communities east of Tampa.
