Hello NL,
My interview for visa is as shown below, went there with my DW and 20 month old baby:

VO: Good morning
DH and DW: hello good morning sir
VO: passports pls
DH: gives him the passports for me, DW and baby

VO was just looking at his desktop (i guess he was going through our applications online form) for about 2 minutes he was just surfing through.

VO: what is your relationship
DH: she's my wife

VO: how long have you been married
DH: January next year will make it 3yrs in marriage

VO: where do you work
DH: I told him

VO: asked my wife also where she works
DW:she also told her cos she's is a trainee photographer

VO: where else have you traveled to
DH: I've been to UK, S/KOREA and both of us have been to UAE and FINLAND

VO: what did you go to FINLAND to do
DH: was invited by a friend to come for his graduation ceremony

VO: tell me what you saw there
DH: emphasized the fact that a friend invited me for his graduation

VO: for the last time what did you see in FINLAND

(at this time my DW was beginning to get worried as I could see it in her and ofcos i was also kinda shivering within)

DH: the place was very cold and i saw nice people and in all it was a nice experience
VO: Give me a short time

(so the VO goes inside and ofcos i dont know what he went in for. After about 3 minutes later he returned)

VO: what are you going to do in California

(California is the place i stated i'll be residing when we get there cos i have an aunt there)

DH: for visit and child birth because my wife is pregnant

VO: whats your budget for this trip
DH: between 9000 to 12000 dollars

VO: how do you intend to pay for your bills
DH: I have a statement of account showing my funds and hands it over to him

VO: Looks through the account statements
VO: OK your visa has been approved and gives us the white document stating how we are to collect it.
DH: thank you sir...

One thing also is that the VO also checks how confident you are with some kinda questions they ask, especially when I was asked about FINLAND over and over...

That was how it went and i wanna appreciate you guys for all the stories I've read here since September this year.

One thing: When you are filling your DS-160 form make sure all the things you wrote there is exactly all you'll say if you're asked during the interview because any difference will result in a denial.

Also take note of the duration you say you're going to spend there. Before our interview i heard one guy that was asked and he said he will be staying there with his wife for 6 months...that is way too long and even if, you must not say this to the VO as they will just conclude you have no strong ties and will be denied. That was how he was denied cos the VO kept on asking him his duration there...TAKE NOTE

One final thing always pray too, very important...PRAYER IS THE KEY...
