can we apply to universties in us which do not ask for gre ?

the following are few of them

1.       University of New haven

2.       NYIT

3.       University of Illinois at Spring Field.

4.       Texas A&M University at Kingsville.

5.     California State University, Fresno

Most of them ask for GRE, I think it is a must for Engg degrees. It " may " be raised during visa interview as to why you didnt write your GRE.

Talk to the schol and find out, in my personal opinion it is better to write it and then apply.
