If you are making your choice of employment based on outrage stories in the media, you are making a big mistake. Of course, some of the stories we read are outrageous. But you should also take into account that literally millions of people cross the border of the US every year (US accepts a million a year only as immigrants, and vastly more as visitors), and vast majority of them have no trouble beyond maybe being asked a couple of questions. Minority of them do have problems, and these problems are a shame, and need to be fixed. But denying yourself opportunities out of fear of a tiny probability you may be unlucky to experience those problems is like never living one's home because accidents happen outside.
