You don't need to cry bro.

B.A have serious issues.From experience many of them could be more discriminatory towards africans than some whites who are racist.

The V.O should have at least heard you out for the sake if your dignity

If your Dad is a citizen, why not ask him to file I-130 for you instead of B1/B2 visa?
