How did los sparragos reattach to the immigration sweep

One day, when Esperanza is packing asparagus, she notices that the strikers have stopped chanting. Josefina sees a group of vehicles coming from the immigration office. They are going to haul away the strikers and deport them as punishment for disrupting the packers and growers. Esperanza and the others are safe because they have continued working throughout the strike, but Esperanza shudders at the thought of being sent back to Mexico alone and therefore, separated from Mama.
