I don't think anyone relishes the thought of being asked or knowing that another traveler is being asked about religious affiliation - likely not often happening but I think it is naive to believe that it is not happening more often to those who dress differently or whose skin is not white. Witness Muhammad Ali's son, and he is a US citizen. Or the student from Montreal with his team.   So I would expect that the numbers of those trying to cross will continue to go down and that the rejection rate will follow.
