Visitor Visa - B2

I would like to thank immihelp. I just followed whatever procedure for document preparation was given in this website for both sponsor and applicant. My husband was the sponsor in our case. My parents had land and home document and pension book. Interview was at Chennai 12 Noon today (1/21) and took them 2 hours. Interview was arranged with a Tamil interpretor. This is what I heard from my parents as questions asked:

They said 'vanakkam' to greet the officer.
Then they asked
1. How many children you have and where are they?
2. what are you doing now?
3. Do you own a house here?

Question to my mom:
Where is your son-in-law working?

That's all, they never asked for any documentation from my parents, they said the passport will come to them in a week's time.

Once again I want to thank immihelp was the step to step lucid explanation they have without which it would not have been this easy!
