I cannot begin to imagine the feelings of those poor people fleeing from persecution in places like Syria and then suddenly finding their dreams of getting to the United States devastated. Actually I can begin to, but only just. In 1984 my wife and I were living in Oregon and that summer we travelled to a conference in Switzerland followed by a visit to friends in England. On the last day I called in at the US Embassy in London and was suddenly told that we were not travelling on the right visa and wouldn’t be allowed in.
