I was unable to get the F1 visa , the VO took only my int.passport and I20 and asked few questions after few minutes he said to me i didn't have sufficient funds for education in the state without looking at my sponsor financial bank statement worth of millions of naira.

Second interview was after a year and six months break from the first F1 visa Interview i had back in July12th 2011 but i've to tell you this my document neccessary for scheduling of second F1 visa appointment came late from the school due to natural disasters that occurred in NewYork and other part of US late year which force me to scheduled for emergency appointment and i was able to scheduled for 16 Jan 2013 which was 5 days away from arrival date on my I20...could this be a factor of visa denial too ?

I was denied again but the VO was concern about my high school graduated year and he asked what i've been doing since my graduation year 2008 but my concern is i'm going for third time interview cause i asked SUNY to defer my admission to Fall 2013 but i'm worry cause i'm currently doing National Diploma programme after i was denied first F1 interview { 12 July 2011 } but i didn't mention that fact /info on my previous D160 online form for both my first and scond F1 interviews {Jan 16th 2013} cause i taught could have a negative influence on the outcome of the result because i'm yet to graduate from the National Diploma programme in May/June 2013 instead i included my working expericence{job} in my father computer engineering company 2011- Jan 2013.

My concern is that can i include that facts { National Diploma } on my 3rd F1 interview D160 form online in June 2013 ,i'll be graduating with ND in Engineering Mangement in May/June 2013 also i'll love to change my degree from Associate to B.Sc in Engineering Science, will all this change influence a positive outcome from my 3rd F1 interview ?

If you could offer a piece of advice to me ,what would it be to favour my circumstance sir ?......... Thanks you all , GOD Bless You All .
