H1B, H4 Visa

First of all a very big thanks to immihelp.com and all the user who shared their experieces. It really helped me a lot, so i am posting my experieces as well.
Jan 24 2014 OFC appointment at Hyderabad, it was supposed to be a cakewalk but i had a bitter experience
appointment time 8:30 AM reached by 8, I came to gowra grand on bike and there was no place to park for two wheelers i have spend 5 mins searching for it but couldnt find any so
i decided to park near a hotel but it was adjacent to main road and traffic police will definitely take it away, luckily i found a place beside Bluedart and DHL, its a paid parking.
By habit i carried my cellphone with me, security did not allow me inside, now i had to find a locker, there is locker facility in a tiffin center opposite to GE i deposited my cell phone there
and charge is 100 rs. Somehow i manager to enter the building by 8:20 and an employee there checked my ds160 confirmation page and there is mistake in my name, name should be as it is in your passport.
She entered my name in a register and told me i can return in another hour or so. We can get it corrected by a person sitting beside the queue but he charges too much, for one form 250, desperate i got it corrected and new confirmation number is generated
After verifying confirmation page they let me inside, i was greeted by one employee he asked if ds160 is modified, i said yeah, he pasted new confirmation barcode on back of passport.
After that finger prints were taken and photograph as well. SO PLEASE TAKE IT SERIOUSLY and no place for leniency. Better get DS160 reviewed by your petitioner before going for anything.

Jan 27 2014 h1b Visa interview was a cakewalk actually

appointment time 8:30 AM, they allow inside by 8:20 or so and we had to wait for sometime before receptionist attaches token number on the passport and we have to wait in lounge looking
at the monitor for our turn and we will be directed to some window where we are going to be interviewed.

Visa is approved.

PS: just because someone was getting grilled doesnt mean VO will grill you too. Students are at receiving end mostly, but a lady before me her case was complicated, her petitioner is XYZ and their partner is ABC and she has to work at ABC client DEF, even VOs head started spinning. VO has gone through all the documents and asked her nearly 20 questions, her visa got approved finally. Just be confident and do a lot of homework/research before going there.
