Hey this is krishna I just want to know that can we get admission in good US university with only toefl score without gre and will that create any problem to get visa and I even have less academic record so please suggest me...

Why USA?
Why MBA?

If the university issues I-20 for you, it's sufficient and should not result in visa denial or delay. However, most schools, especially the well known, accredited ones require high scores on both TOEFL and GRE.
