Fair enough... Just like Kaptain it's reasonable.

Well, I don't know how to use the reply box on this platform, so, I'm just gon' type straight ahead.

A big thank you to @Seyewest and @Kaptain for their response to my enquiry.

I traveled light with Etihad through Abu Dhabi and did Customs pre-clearing there. The airport was so large and modern, replete with facilities you would not even find in the US. Traversing from arrival to the departure lounge was one hell of a journey. Food and any other thing you want to buy instantly became unaffordable, lolxxx. Met some two other Nigerians who were also traveling Stateside for school. One of them lost his garri and Egusi kept in his hand luggage to @CBP. Layover was long - 8hrs, but it afforded the opportunity to look for food similar to our naija menu.

Finally, it was 23:30 local time and CBP opened counter. Was first on the queue and it was like old friends gisting. Here's the transcript:

CBP: Hello
Me: Hi
CBP: What are you coming to do in the US?
Me: To visit wife and kids
CBP: Smiling now. Oh! They've been here before you, vacationing?
Me: Nah! They're LPRs and I've not seen the kids in one year.
CBP: Really? Hope your wife has filed in for you. Do you have a priority date now?
Me: Yes, thanks for asking
CBP: What do you do?
Me: Told him my profession
CBP: Which University did you attend?
Me: Told him. Have you heard of the school before?
CBP: Smiles. Nah. Just asking. Shows me my bags on the screen and asked me to confirm ownership. He then told me he'd check my answers against my ds 160 and visa interview transcript.
Do you have anything to declare like alcohol, agricultural produce
Me: Fish, .....
CBP: Ok don't worry, welcome to the United States, have a nice stay.
Me: Thank you very much.

Flight took off at 03:35hrs and got to JFK after 12.5hrs in the air.

Still enjoying my stay, New Castle, Delaware is the place.

Hello VO,

Thanks for your good work on this forum.
Having been denied once previously, I applied for a B1/B2 visa as an applicant with a pending immigrant visa petition, armed only with the responses you've been giving here. The preparation was key as the visa was approved.

Now my issue is that my wife and kids, who are US LPRs, became overly excited (I am too ) and want me to stretch the vacation a little. They want me to travel a week before the date I wrote on my ds 160 form but still return on the date indicated (making 18 days instead of the initial 10 days). Kindly enlighten, does this constitute an offense or improper use of my B1/B2 visa? We are sticklers to rules and don't want any trouble as per the IV petition or even this B1/B2 visa, so we decided that I should pose the question to you. Thanks in anticipation of your wise counsel.
