A friend wants to visit a second time within her 1 yr B2/M visa. As is true for going to China, the visitor shows RT air booked, an itinerary with hotels, etc to get the visa issued. But, if she wants to travel a second time (first visit was only 6 weeks) can she just purchase tickets and interview at the POE? Would this be normal procedure? Thanks and, yes, I have searched but after reading about 5 or 6 threads, I thought I would ask this. Greg
