I would not take that risk as my parents were returned coz they applied for VISA mentioning "my sons graduation" but at the port of entry they were told your son already graduated why are you coming so late after graduation. I so much regret for not having money at the time of graduation to have them over and now I could not have them here at all. It was a total waste of money as I lost the money for the ticket. Not only that their VISA were voided so their visit to US is a miracle.
