My parents went to Chengdu for their first visa interview, but were rejected.
Five questions were asked:
VO: Why do you want to go to US?
Parents: To attend my daughter's graduation ceremony.
VO: Have you been to US before?
Parents: No
VO: when will you go to US?
Parents: Next March
VO: How many kids do you have?
Parents: 3
VO: Show me your house title.
Parents: sumbit one
Then VO rejected their application.
Comments: my parents gave very short answers to each questions, and they did not have a chance to show all the supporting documents including pictures and bank statements. Though they sumbit the invitation letters along with their D156/7 forms, VO didn't care having a look.
My parents told me that it seemed that all the parents were rejected yesterday.
