Thanks a lot to everyone for answering my queries. I really appreciate the help provided.
I sponsored my Mom and the following questions were asked by the Visa Officer
Mom: Did your daughter study in INDIA?
Mom: Did she get married in INDIA?
Aunt: How many kids you have?
Aunt: Why your husband is not accompanying you to USA?
Thats it and then the VO said that your VISA is approved
Thanks once again.
