Dolores Bustamante has been in this country for 23 years. On Thursday, she was given 30 days to decide whether to self-deport back to Mexico. If she decides to do so, supporters said, relaying the federal directive, she has another 30 days to leave. “Right now, I am not thinking about this. I just want to rest,” the 54-year-old farmworker said in Spanish, speaking through an interpreter a day after being released from ICE detention.
