Visitor Visa - B2

My parents VISA interview was scheduled 16th April in Mumbai. We had opted for Marathi translator. First thing we observed was that the appointment letter says to come just 15 mins before the interview. But infact they start allowing people to enter the office 1 to 1.5 hrs before. So it is recommended to reach atleast 1 hour before.
During the interview no documents were asked to be shown. They asked 5-6 questions:
1. Why do you want to go to US
2. Why do you want to go for 6 months
3. Where are you working
4. Where is your sponsor working
5. Will you go back to US after this trip
6. How many children do you have ? What do they do - (to my mother)

Your VISA is granted. Have a pleasant trip to US!!!

My parents were stopped several times while talking & were told to answer only the question & not to give more details. Also they said no documents are required ... just answer the questions !

Though docs were not required, the docs helped my parents a lot in understanding & preparing for the interview. Few things in favor of my parents:
- My father is working & not yet retired
- He had got a leave approval letter for 6 months from his company which stated that he will resume work after his US trip
- He also had company bonafide certificate
- He replied to all the questions with confidence

One most important thing which I did was that I read all the instructions on all the pages of immihelp. It is a gr8 resource. If you prepare the docs as directed & go through the interview questions gettting VISA becomes easy.
