H1B, H4 Visa

First of all, thank you for your valuable experiences here in this site. They are very helpful in preparing for the interview.
It's time to share my experience.

My interview was scheduled for 8.00 clock on 2/25, I reached center earlier so asked me to come back at 7:45. So, I went to nearby Starbucks and returned at 7:45.

After that security person checked my appointment copy and asked me to wait inside. There are like 10 people before me.

A word of advice don't carry anything not necessary, I saw they send someone outside, may be they hold some items.

I gave my passport, appoint confirmation, Ds160 and I797 confirmation to the lady at the front desk. She asked me what is your Candian status said Visitor. Then she asked me to go to either 2 or 3 window inside.

After that security guards scanned my stuff and I noticed they have cupboards to keep our cellphones and other items. The basket is small so a mobile phone, hotel key guards can fit in. You can your walet with you.

After entering inside I saw we can take pictures inside. Which is like 5 Canadian dollars. In case you forgot to get them. Make sure you have a 10 dollar bill.

While am waiting for my turn am a bit nervous looking around and memorizing and processing what to say.

My turn came and I went to second window, she greeted good morning, then am asked my passport, Ds 160, i-797, photo and gave appointment confirmation. The lady at the counter told me appointment confirmation is not needed. So I took it. Asked questions like is it your first h1b. I said yes. Then after few mins she gave back my passport, i797, photo and ds 160. Then asked me to go to the next counter number 4. This lady

On counter 4 she greeted me good morning I am asked my passport, ds 160, i797 and she took my finger printing and asked me to stay in the line and wait for my turn for the interview. She also gave me the know your rights pamphlet. Asked me to check them meanwhile and interviewer might ask you. Then i has a few glances and finally my turn came.

luckily, i have a seat to sit. Sat relaxingly and greeted her good morning and gave my passport, ds 160 and I797

It's okay to ask second time if you don't understand. Personally I did myself.

Am still waiting for my Passport. one day passed excluding interview day. Even though VO said you are approved, the status is administrative processing. I will update once I get my passport.

bottomline, almost all of them who's been interviewed prior to me are approved.

All thes best for the folks attending their interviews in near future. I tried my best to cover everything I experienced, observed, and asked. Hope this helps you guys.

good day !!!
