Do you have a source you can share for that assertion?Once accepted into the PhD program, BK, would have been REQUIRED to make graduate student visits to WSU. The school pays for travel, hotel and food for these visits.
I asked my better half about his experience with grad students visiting after acceptance. Different university (UI vs WSU) & different department (political science vs criminal justice) & his answer was, “Some do, most don’t.” His perception was that it was more common earlier in his 3+ decade career than in more recent years.
