Many people who are in the U.S. illegally have been allowed to stay in the country for years, as long as they didn't commit a crime. They've had to check-in regularly with federal immigration officials, and in the meantime, many have gone on with their lives. They have families and careers, despite their legal limbo. That's changing. This year, President Trump granted broad authority to the Department of Homeland Security to deport unauthorized immigrants far more aggressively. Now many of those routine meetings end in arrest, detention, and deportation.That's what happened to Moussa Mahaman a 53-year-old originally from Niger in West Africa. He overstayed his visa in 2003, and said he feared violence in his native country. He was detained a few weeks ago, and this week, he was deported.
