Visitor Visa - B2

Dear Immihelp Admins - Please accept my gratitude and appreciation for maintaining such a one stop well informed website. Reading through the forum here helped me in confidently applying a Visitor visa for my mother who is a widow.
Want to share my experience as well here.

Interview was scheduled on 10 Oct 2013 @ Chennai consulate.
Background: I am the only child and I lost my father 3 months back and I was desperately hoping for a Visa for my mother so that she can come over and stay with me. I am on L1 with my Visa expiring in Nov 2013. However, my i-94 is valid until 2016 as per my last entry to the US. My wife works here as well with her EAD.
The visa was applied with me as the sponsor though my mother could showcase that she is able to bear the expenses. My mother speaks fair English but I did not want to take a chance with a mis-understanding in the Accent and took the interview in Kannada. My parents had visited me for 2 months when I lived in the UK, so there was a record of successfully returning back to India before the visa expiry.

To my surprise, my mother told me that the Visa Officer was of Indian origin who spoke Kannada. My mother greeted the Visa office with a smile and a Good morning Sir.

In Kannada -
VO: Who are you visiting in the US?
- My son
VO: What does he do in the US?
- He works in abc company
VO: Your Visa is approved. You will receive your passport in 3 working days.

It couldnt have been any better than this although I had prepared a questionnaire of ~50 questions for my mother from this website and some specific to our case. I had highlighted the words that explicitly needed to be stressed when the question was asked. There were no documents checked but my mother had the following documents handy:

Sponsor docs:
- Letter from Employer + 3 months sal slips
- Letter from Bank + 6 months statements
- copy of old and new passports
- Letters to consulate and my mother
- My Birth certificate
- Last 2 years Tax returns in the US
- i-94 copy(you get it online) highlighting validity of stay

My mothers documents to show ties:
- Copy of her bank statements showing running balance
- Property document(plot+house) that is in my Late Father's name
- A photo of our residence + Family photo
- Pension was still under processing so the Bank did not issue a letter. However, father's pension is routed to my mother. So had asked mother to show record of Pension deposited in the last 2 months in her account.

Hoping this will give some confidence to folks in similar situation as me. I was very skeptical considering the fact that my mother was attending the interview and making her case in less than 3 months of losing my dad. Just make sure the form is accurately filled and the candidate is well aware of the details in the form.

Thank you again immihelp!
