Parents 2000 Pass

My parents have been rejected once in Apr. This time we add more documents like Senator Letters, Invitation Letter, Phone Call record, full page copy of passport etc. to show the strong tie with China. And finally the visa officer is conviced and issued the B2 visa.

I have not get all details from my parents, and will update the interview process later. The interview process for my parents took >30 minuts, which is a very painful long time, compared with other people's 2-3minutes. I still don't know the reason yet.

It seems the B2 visa denying cases increase substantially recently. Maybe due to the high volume of applicants during summer time.

Thanks for all the information I got from here. And good luck to anyone who is applying visa.
