In the pictures, Jess Enriquez Taylor wears artful makeup and her hair is carefully styled. But her face was bare as she rode the bus toward the international border one recent afternoon, and her long black hair was tucked under a hat. One of her hands was painted with glittering nail polish, but she kept it folded and out of sight. She used the hand with no polish to point to the images on her cellphone. “This is me, this is who I really am. When I get out of here, I transform,” she said of the photos, taken on the other side of the border, in the United States.
