The enforcement ramp-up has sparked fear in immigrant communities around the country, with some people avoiding unnecessary outings and keeping children home from school, according to interviews with migrants and advocates. Hospitals, schools and libraries have adopted new policies to limit cooperation with ICE.

Among those caught in the enforcement dragnet: Riyer, a 27-year-old Venezuelan man detained by ICE in the Atlanta area. He fought back tears as he worried about how his 22-year-old partner and their 5-month-old son would survive without him.

“I keep thinking of them alone,” he said while detained in Atlanta shortly before being transferred to Stewart Detention Center in Lumpkin, Georgia.
