Am a 400lvl student in a federal university studying Mathematics here in Nigeria, I am so mean to have my M.Sc in computer science from a reputable university in The United States. Have been hearing and reading a lot of issues about denial of Visa here on NL so i would like if someone could guide me through on how to start processing. I am the last of the 4children in my family, my dad is a retired civil servant (retired Feb. 15) , I have two brothers and one sister, My eldest brother is a civil servant and also own a Business(printing on polythene) and I think he is financially OK, the other one is self-employed. My sister is a teacher in a secondary school. I would love to know the minimum amount for tuition fee and living expenses in any reputable university over there(my dad is retired and yet to receive is gratitude/pension but from the little he saved he can still give 4million Max and my brother can still support with 2million max) i can still afford to pay for my flight and visa and for my exam any exam i must take(profiency in English).
The only related person i have there is the sister of my sister's husband.

what are steps needed to start processing??

what are the chances of me given visa?

do you think the fund at hand now is enough to see me through for my stay?

is there anyway the govt. there could finance me and i work for them after my studies?

do you know of anu individual/organisation/company that is capable of financing me and i work for them after my studies

do you think am being too ambitious, maybe i should just forget studying there?

or US isn't the place for me mayb i should set for Europe(where in Europe)??

Between is there any scholarship for my kind(an first class student currently on 4.63/5.0 scale)

Thanks in anticipation.
