I am interested in studying international trade or business in college. Does anyone have any ideas for related high school jobs or internships?
Unless u have a family/friend connection, it’s almost impossible to get a significant internship as a HS student. Businesses/organizations typically select college students. Accordingly college admissions officers don’t expect HS students to have internships.
HS internships are quite rare I believe, but why don’t you try checking out sites/companies that offer internships and try to ask them whether they offer internship for HS
