"That chaos has the potential to be very bad for business. Tech companies rely on immigrants — including from the predominantly Muslim countries covered by Trump’s temporary travel ban — to fill many of their most important engineering positions. Energy companies count on being able to move workers in and out of countries around the world. Manufacturers have supply chains that cross international borders.
