i have a friend who passed all the foreign exams.. and was fortunately granted a tourist visa.. she went to the states but the immigration asked her so many questions.. her purpose of visiting usa was just to visit her relatives. i dont know what had happened. the immigration knew that she is a nurse and asked her so many questions.. sad to say, but she was sent back to the philippines at that very moment.. airport to airport. and her visa has been cancelled. she advised me not anymore apply for a tourist visa. what do u think?
