I am studying law now. I just transferred from the Master program to the J.D.
program which is not good for my parents' visa.
However, the officer just asked three questions:
1. When did your daughter go to the U.S.?
2. Do you have copy of her passport?
3. Can I see some pictures of hers?
Then they passed!! He did not even ask my father any questions.
Thanks for all information here! Best luck to everyone!
