Migrant families and immigration advocacy groups are preparing for the possibility that millions of families could be separated during the mass deportations planned by President-elect Donald Trump.

Trump has said he will prioritize criminal noncitizens for deportation, but has not ruled out separating or deporting families. One U.S. citizen whose husband is undocumented got passports for her U.S.-born children and plans to get a power of attorney drawn up. "If something happens and my husband is detained or he’s deported, it would be very difficult for me to get passports for my children, for our children, to be able to leave the country to go see him," she said.
