It can be very challenging to assess admission chances for international students.
- colleges usually don’t publish much admission data broken out for internationals;
- the Common Data Set does not cover IB Scores;
- you have not provided your class rank or an unweighted GPA (which might not be too meaningful, even if you did).
The CDS does indicate the percentage of internationals enrolled in each student body … but it’s not clear to me that a relatively high number necessarily is good, or that a relatively low number necessarily is bad, with respect to admission chances.
In your case, the most useful piece of data we seem to have is your ACT score.
You may want to focus on schools with composite scores below 32 or so.
Possibilities (small to mid-sized schools, ~near either coast, that seem to have respected business programs):
Northeast
Boston College
Bentley
Mid Atlantic
Villanova
George Washington
University of Maryland (College Park)
South
University of Richmond
Wake Forest
Washington & Lee
Emory
Tulane (not on either coast)
West
University of Southern California (much bigger than you may want)
Pepperdine
I’d say all of these are high matches or reach schools in your situation
(but I doubt any are out of reach for a full-pay international student with your scores).
