Please kindly help me with some reasons why my visa was later denied. Here is my interview experience at US embassy abuja.
My interview is scheduled at 8:00am on Wednesday 11 march, 2015, but i arrived there 30mins before, here goes the interview:

Me: Good Morning Madam
VO: Gud morning
VO: Where are u going?
Me: I replied
V.O: What re u going there to do?
Me: I replied
V.O: Where re u working?
Me: I replied
V.O: What is ur designation? And can u tell me ur role?
Me: I replied
V.O: Have u traveled before?
Me: I replied - Kenya nd Dubai
V.O: K...type something on system, and later gave me "Visa issued collecting paper"
Me: I collected it frm her and said "thank you". And immediately i left.
But on d day i was preparing to go nd collect my issued visa (Friday), i received a call from US embassy that i am invited for an interview either Tuesday or Thursday nxt wk...wen i got there on Tuesday, the V.O greeted me wit smile "Gud Afternoon" and just handed over my intl passport back to me and said she was sorry that there was an information received about me after my interview which proved that i am not qualify as eligible immigrant to issued a US visit visa....dat i should reapply in future.

na wa o so sorry about this

may be there's a misinformation in your application form

next time be careful and also pray. .

cos it's rather strange.

It is well

They gave you a reason...but did not specify. Maybe they found out you beat up your wife some time ago.... made some false statement.... if Muslim you may have a name similar to someone on a terrorist no fly list....should've asked them. Keep applying...they'll keep receiving your fees and denying you visa. Move on with your life.
