No additional documents
max2k1 & Josh818,
There was no change in the documents she carried. In fact, she used the same two months old documents, I had sent earlier for her first appointment. Only the DS-156 form was new ( obvious ).
Here interview took less than 10 minutes, this time. She was asked only three questions:
1) What is your name? - Ans: My name is xxxxx.
2) Who are you visiting in USA? - Ans: Son-in-law & Daughter - our names.
3) How long are you going to stay - 3 months
and she was granted a visa - 10 years - multiple entry.
GOD only knows on what basis they deny/grant a visa!
Good luck,
Rasi
