Getting into U.S grad collage as an international student

I’m thinking about applying masters program with Aerospace Engineering in U.S.
I have done my senior year in Cal State Fullerton for one year as an exchange student, and I would like studying in U.S.
I have 3.3 GPA and 3.44 major GPA from my Korean university and 3.8 GPA (major) from CSUF in senior year.
I knew that I need TOFEL and GRE to get into U.S collage.
Acutally I do not have much info about which universities are enough to enroll for master grogram with my grad.
However, I just want to know how much GPA can be needed in order to apply some universities which are well knowns in Aerospace engineering field.
Thanks.

Sample a variety of department admissions pages where it will discuss requirements. Usually there is a minimum of gpa 3.0 for grad admissions, but that may not be sufficient. I don’t know how your overseas is considered. But you might also calculate your last 60 units or last 2 years, or just major classes as that is more important.

Cal Poly Pomona:
Admission requirements for the program are*:

B.S. in Aerospace, Mechanical or a closely related field of engineering from an ABET accredited institution received within the last 5 years.
GPA in upper-division undergraduate courses in Math, Science and Engineering needs be ~3.0 or higher.
If B.S. received from non-ABET institution or prior to 5 years ago or lower GPA than ~3.0, then GRE test score (quantitative + verbal) of at least 1100 is required.
