Hi you all, I know I am here late. Pls I need your help here, I already have an invitation letter to Portland USA, and I am applying for a B2 visa. Before & after filling the online DS 160 form. What will be my challenges? Do I really need a tax, huge money in my account.? - since I already have where to stay for the 3 months in the US..

I am married with 3kids, and I run my own business - a registered enterprise business here in Nigeria.

Pls good guys help me in details as I've read some post here but they didn't match my request to know if I will be granted a visa 1 time or not
