Silicon Valley is in an uproar over a proposed new executive order that would overhaul the existing policy on foreign worker visas. The Trump administration’s goal apparently is to prioritize the hiring of American workers first and make other changes in the way U.S. companies can recruit skilled professionals from other countries. The president reportedly wants to revise existing policies on how American companies hire foreign workers in a way that would force them to consider U.S. citizens first and foremost, a draft of the order suggests.
