"The Department of Homeland Security’s latest plan to keep us safe would require U.S.-bound foreign travelers to register their travel plans 48 hours in advance, if they are coming from a country whose residents are not required to obtain a U.S. visa. What effect do you think this will have on international business travel to the U.S.? How would you react if foreign governments retaliate by imposing a similar rule on U.S. travelers?
